Home : Industry Scenarios
ViewDS provides a range of customer focused capabilities including
Organization Charting, User Self Service, ePresence Social Networking
front end and White Pages as user friendly authoritative sources
of identity information. It also provides Integration with Lotus
Same Time (with Microsoft OCS integration underway). ViewDS has
a unique configurable User Interface and is the only technology
to incorporate LDAP, X500 and native XML compliance on a single
platform. ViewDS is also the world's first commercial directory
to offer Component Matching and support of XED as well as supporting
search and matching of Chinese language, and other non-Latin characters.
ViewDS builds on these world firsts with the evolution of "directory"
to "discovery." This, with a single point of administration
eliminates unnecessary duplication and when coupled with high speed
search and matching of data elements makes for an extremely powerful
and versatile tool.
As examples ViewDS can be deployed across any of the following
industry scenarios:
Directory Services Providers
ViewDS provides a key technology platform capability for any
Directory Service Providers (and US Based PSAPS - Public Safety
Answering Point) keen on embracing the On-Line
market.
ViewDS provides the Directory Service Provider with a high speed
search capability from the Web, Mobile Phone and PDA with 24x7 reliability.
It’s robust and efficient “telco” heritage and
scalability provides the environment Service Providers require.
ViewDS thus provides an Integrated Directory service platform
from phone books through to white/yellow pages, directory assistance
support to Call Centre operators with internet and mobile phone
access.

Telecommunications Carriers
With its scalability to millions of entries and sub second response
times, ViewDS is an ideal platform for a variety of applications
within a telecommunications carrier. Its highly usable integrated
search facilities coupled with it 24x7 availability, centralized
management of distributed service and adherence to standards provide
applications such as:
• internal and customer directories,
• call centers,
• casual Internet Web users,
• delivery of white and yellow pages,
• SOAP enabled applications,
• enquiries using WAP enabled Mobile phones.

Internet Service Providers (ISPs)
With increasing competition, ISPs need to provide low cost basic
subscriber services for millions of subscribers. At the same time,
they need to differentiate services with added value capabilities.
Directories are becoming established as a central component in the
provision of these subscriber centric services.
ViewDS also provides a key and efficient method for providing storage
of account information with subsequent high speed authentication
services. The deployment of ViewDS:
* Provides a User Self service capability for customers
* Allows the segregation of services using Role and Attribute based
access control
* Provides applications that enables the migration of users from
free to paid services
* Ensures services and service access is totally secure
* Aggressively controls costs while expanding both the number of
users and the number of services
ViewDS is a fast, efficient and scalable way to store, manage, search
and retrieve data on lots of moderately complex objects. Its ability
to store XML schema and retrieve XML data using component matching
as well as its ability to efficiently replicate information across
multiple servers provides the mechanism to hold information on customer
accounts.
In addition, ViewDS Smart Connector provides the capability to synchronize
information between merging ISPs should that be required.

Mobile Network Operators
ViewDS can be deployed by a Mobile Carrier in its core network
to create a single repository for subscriber information and service
profiles. ViewDS is one of the industry's most scalable, reliable
and comprehensive directory servers which provides the operator
with the core infrastructure needed for current and next generation
service requirements.
Mobile carriers are moving to simplify the core network by the
introduction of a single independent directory with the performance
to deliver real-time access to subscriber information. With telecommunications
legacy infrastructure becoming a commodity, providers need to increase
competitive advantage in the market by delivering an open, scalable
environment that places them fully in control of subscriber data.
ViewDS provides real-time access to subscriber data which with
the introduction of multiple access points, advanced devices and
next generation IP environments, is becoming extremely important.
ViewDS supports the very latest in Internet Protocols (IPv6) and
provides for comprehensive support of industry standards such as
XED, LDAPv3 and X.500. Its 24x7 capability fully supports
the service continuity requirements of the Mobile operator.

Identity Trust Service Brokers
An emerging trend in the US has seen the growth of independent
organizations set up to provide Trusted Identity Broker Services
in a world where organizations are spending more time and resources
trying to find, access and share critical information. In addition
to the cost and productivity impact, cross organizational information
and application sharing can introduce a significant level of complexity
and risk to operations. Federated Identity Management offers an
answer to the surrounding cross organizational information sharing,
but it can be costly and complex to deploy.
Industry experts estimate that the annual administrative cost associated
with ID Management can average A$150 per user per ID. Add to this
the cost and complexity associated with :
* Connecting end points (i.e. registration with different hardware
& software configurations)
* Support for different authentication schemes (SAML, XACML, 1
and 2 factor authentication etc)
* Protocol Translation
* Audit & Reporting
* Trust Agreements and rules and policy enforcement
The result has been a growth of ASP Based vendors offering managed
and hosted services for Federated Identity Management. ViewDS provides
a core component for the delivery of fast and cost effective solution
to Federated Identity Management for cross organization linkage
with the capability centralize and automate the process of exposing,
accepting and monitoring digital identities across security domains.

Public Key Infrastructure (PKI) and Trusted Third Party deployments
Directory Services and Identity Management solutions provide the
foundation of digital certificate identity verification services.
These are offered by Trusted Third Parties (TTPs) for a range of
PKI and Time Stamping services on behalf of industry associations,
corporate organizations, government and citizens.
The deployment of ViewDS provides TTPs with the ability to support
rapidly growing user populations while containing costs in the provision
of secure authentication services.
ViewDS is designed to provide a 24x7 Provide 99.99% availability
of service to conform with Service Level Agreements which are typically
required of TTPs. ViewDS also has a number of unique features designed
to support deployments of PKI. ViewDS’s support for Password
Encryption, Strong Authentication using X.509 PKI certificates.
More importantly its Component Matching capability and the implementation
of the RFC 4523 PKI Matching Rules ensure rapid processing and retrieval
of information such as Certificate Status.
X.509 certificates can be stored by most directories. However,
few directories support any matching rules for the PKI attribute
syntaxes. ViewDS supports the following matching rules from X.509:
• certificateExactMatch
• certificateMatch
• certificatePairExactMatch
• certificatePairMatch
• certificateListExactMatch
• certificateListMatch
• algorithmIdentifierMatch
• attributeCertificateExactMatch
• attributeCertificateMatch
RFC 4523 defines the LDAP representation for most of the PKI matching
rules. As an example, an LDAP filter to search for the entry containing
a user certificate with the serial number 12345 would look like
this:
(userCertificate:certificateMatch:={ serialNumber
12345 })
ViewDS also supports the component matching rules (RFC 3687), which
provide additional matching capabilities beyond those specified
by the matching rules in X.509.
ViewDS has index support for each of these matching rules so that
the entries of interest can be quickly found regardless of the total
number of entries in the directory.
Thus the ViewDS directory deployed as the certificate and CRL repository
provides PKI applications with a fast, reliable and efficient environment.

Defence Messaging
The CCEB standard military messaging standard, ACP (Allied Communications
Protocol) 123 or the European STANAG 4406 standard protocols are
increasingly being used to deliver military messaging between defence
forces.
To support military messaging, there is requirement to provide
Directory Services in accordance with the CCEB ACP 133 standard
and NATO STANAG 4406. In addition with the emergence of joint coalition
task forces to conduct operations, there is a need to deploy common
Messaging and Directories gateways to link nations. This has led
to the establishment of another CCEB protocol, ACP 145. ViewDS is
fully compliant with the CCEB ACP 133 Edition C standard and the
CCEB ACP 145 standard.
There is also the need to provide support for a combination of
signing and encryption on a desktop to desktop basis. This means
that at network gateways between units and networks, there is a
need to deploy a High Assurance Guard such as Clearswift EAL4 Deep
Secure product. ViewDS is fully tested and deployed with the Clearswift
Deep Secure EAL4 High Assurance Messaging Guard which requires 2
x ACP 133 Edition C compliant Directory servers. In this deployment,
as well as directory message addressing information, the Directory
stores information such as Security policies and Anti virus index
files and uses Strong authentication together with component matching
to access digital certificates for authentication and encryption.
ViewDS can also be used for the support of Tactical Military Message
environments.

Defence white and yellow pages and as repository for defence role based access control
A Regional Department of Defence had a challenge. How to keep track
of its people and how to use its central identity management infrastructure
as a basis for online services. Historically, internal divisions
had 'gone their own way', and developed a wide variety of corporate
directories.
These were constantly in need of update, were not integrated, and
offered very poor performance, which discouraged their use. Headquarters
took steps to overcome the problem by acquiring a single, easy to
maintain corporate directory, capable of integrating with a diverse
collection of legacy and new systems, able to be accessed via the
Web as well as from Microsoft desktop platforms and mobile devices
and offering significant performance improvement in a cost-effective
manner.
ViewDS was selected due to its high level of compliance to the
ISO OSI Directory Standard. It offers both DAP and LDAP interfaces
as well as full support for the new IETF XML enabled Directory standard.
It also offers SOAP, LDIF, ELDIF and a variety of other standards.
ViewDS was easily interfaced to the Defence Department's wide variety
of disparate legacy systems, which included email, a proprietary
HR system, other more standard HR systems and a telephone database
as well as a variety of systems on both the Defence Secret and Restricted
networks . Existing legacy systems remain and are dynamically linked
to ViewDS, allowing for either periodic update or live linkage.
Changes made in ViewDS are reflected in the legacy systems, or visa
versa depending upon the specified relationship.
The new Identity Management infrastructure Directory is accessed
through a specially configured ViewDS Web Directory User Agent (DUA),
offering simple but powerful search capabilities, including phonetic
and intelligent sub-string matching. Users can search for a particular
person, or browse through the entire directory. The system administrator,
using either a Web based or Windows DUA, performs administration.
This allows full maintenance of all data records, the ability to
move entire branches by a simple drag and drop operation, system
backup and report generation (including production of a paper based
directory when required). An SNMP interface links ViewDS to the
Department's on-line systems monitor, providing real-time systems
performance monitoring.
The Regional Defence organization with its requirements for mission
critical performance has multiple ViewDS licences and requires 24x7x365
operation with 99.99% availability.

Defence Tactical Deployment
Defence CONOPS (Concept of Operations) deployments as part of the
ORBAT (Order of Battle) Defence Task Groups will typically have
one or more Tactical Headquarters (HQs.) Each of these installations
will have sophisticated computing and communications infrastructures.
In most cases a number of tactical directories will be used to
support messaging and other communications infrastructures in each
of these HQs. As Defence organizations rely more on NCW (Network
Centric Warfare) environments, this requirement becomes critical
and normally Tactical HQs will be at least duplicated with one HQ
echelon always on the move in null mission control situations whilst
the other is up and running operationally.
This infrastructure for a tactical HQ will typically be put together
over a few days before an operation. In these cases , setting up
the directory, and tearing it down must be achievable, straightforward
and fast, as well as easily repeatable to support multiple sets
of infrastructure, and partial or total destruction of this infrastructure.
The key for this situation is ViewDS’s support of X.500 DISP
where each Directory can receive just the minimal amount of information
it needs to function. ViewDS is also very easy to use and provides
a variety of functions designed to make it ideal in the Tactical
deployment scenario.
ViewDS also has the ability to manage Directory servers remotely
using secure remote authentication.
In addition, ViewDS supports Organization Charting and Alternate
Hierarchies and Movement of Government changes. These three capabilities
allow operational staff to move military, naval or air units between
operational formations and display them in alternate hierarchies
to normal ORBATS.
ViewDS’s support of acronym and synonym matching provides
the mechanism for Defence Nomenclature such as US, NATO terms such
as BDE=Brigade or ARV – Armored Recovery Vehicle to be fully
supported as part of its searching and matching capability.

Defence JC3IEDM XML Knowledge Repository
The application of military force in the early
21st century is demanding. It covers a wide spectrum of threats
and deployment scenarios that range from conventional general
war through to limited operations, crisis response operations,
asymmetric conflict, and terrorism. Unilateral capability is important
to nations but most planning is made on the assumption of alliance
and coalition operations in scenarios that are difficult to predict
and which often arise at short notice. Thus the nature and composition
of a force structure to meet military requirements will be specific
to requirement and based upon a general and flexible military
capability.
To achieve this, an assured capability for interoperability of
information is essential. The successful execution of fast moving
operations needs an accelerated decision-action cycle, increased
tempo of operations, and the ability to conduct operations within
combined joint formations. Commanders require timely and accurate
information. Also, supporting command and control (C2) systems need
to pass information within and across national and language boundaries.
Moreover, tactical C2 information must be provided to the operational
and strategic levels of command including other governmental departments.
Additionally, forces must interact with non-governmental organizations,
including international aid organizations. The Multilateral Interoperability
Program (MIP) aims to deliver an assured capability for interoperability
of information to support joint / combined operations. The aim of
MIP is to achieve international interoperability of Command and
Control Information Systems (C2IS) at all levels from corps to battalion,
or lowest appropriate level, in order to support multinational (including
NATO), combined and joint operations and the advancement of digitization
in the international arena. The means to achieve this is known as
the MIP solution. The current version incorporates additional development
and the data from the NATO Corporate Reference Model. As a result,
the scope increased and the name was changed to Joint C3 (Command,
Control, and Consultation) Information Exchange Data Model (JC3IEDM).
The extent of requirements agreed by the MIP nations is to define
only the information that is to be exchanged rather than all of
the information that would normally be required by a national
system. Consequently, JC3IEDM is first and foremost an information
exchange data model. The model can also serve as
a coherent basis for other information exchange mechanisms, such
as message formats, currently lacking a unified information structure.
The MIP information exchange data model enables command and control
system interoperability based on shared information exchange standards
and protocols developed through an international process that
has built operational and technical consensus in using XML technology
in applications and services has created an opportunity for MIP
partners to collaboratively produce and share capability to implement
XML- based data exchange solutions. The JC3IEDM and its business
rules define the MIP shared vocabulary, grammar and business rules
for information exchange and define the required baseline semantics
for implementing XML-based data exchange and processing.
Any given version of the MIP IEDM can be transformed to define
XML Namespaces, in turn suitable for building reference XSDs that
can support XML-based consultation, command and control (C3) information
sharing within the MIP community. Hence, ViewDS can completely support
the JC3IEDM model and also leverage its full capability to search
(using component matching) and control access using both Attribute
based and Role Based access control to any of the underlying data.
It can also fully support the Object model and fully integrate it
to a Policy based Access control model (as required in the NATO
C3 Technical Architecture NATO Network Enabled Architecture strategic
recommendations. Nations need to be supported by role-based,
information access, mechanisms that can be dynamically configured
to reflect changing policy governing the sharing of and access to
information

Proxy Directory Guard
ViewDS can be used as a Proxy X.525 Directory server when deployed
in the Directory Guard scenario. In this scenario two ViewDS licences
are deployed with the Clearswift EAL 4 evaluated Directory Bastion
Guard solution. The Clearswift Directory Bastion role is to provide
assured network separation supporting only the DISP ITU-T Rec. X.525
protocol between explicitly identified Directory servers deployed
in a Red Black network configuration where data is required to be
synchronized between directory servers on two otherwise disjointed
networks.. That is two networks operating at different classification
levels or similar levels, but where classified network separation
is required. ViewDS is deployed on both sides of the Directory Bastion
and supports strong authentication for all server to server operations.
Because DISP is the standard protocol to synchronize directory data
between ViewDS servers, a Directory Bastion can be inserted between
two ViewDS servers without requiring anything other than normal
shadowing agreement configuration on the ViewDS servers. Apart from
network level addressing, the Directory Bastion is entirely transparent
to the ViewDS servers.

Hub Coalition Border Directory
One of the requirements of Defence Forces worldwide is the support
of coalition operations and inter-coalition communications. A fundamental
requirement of Network Centric Warfare (NCW) between Coalition Partner
for Peace nations is the deployment of an ACP 145 Coalition Gateway
and a Coalition Border Directory.
This Directory needs to hold key addressing information and security
policies to allow communications between Allied Forces. ViewDs has
been fully tested and deployed in this scenario as Australia’s
Border directory and in communication with Border Directories used
by a number of other countries including the United Kingdom. With
its support for X.525 Directory synchronization protocol, ViewDS
has also been deployed in the Allied Border Directory scenario and
has been used by a CCEB country in a number of JWID and CWID programs.
ViewDS has undergone extensive testing with the Nexor Military Messaging
system and the ISODE Directory Servers in this Border role.

Government White Pages eBusiness Yellow Pages
There is increasing pressure on governments and their agencies
to provide online services, usually referred to as eGovernment services,
which allow citizens to interact more easily and efficiently with
the Government.
By deploying Identity Management solutions, governments will:
• Provide for the introduction of secure eGovernment services
• Provide authentication services for all citizens
• Aggressively push eGovernment services for rapid adoption
• Ensure that citizens can interact securely online with the
Government departments
An on line discovery service solution such as ViewDS provides a
guide to key people, organizations, functions undertaken and services
delivered by the Government. Both Federal and State Governments
deploy such solutions and they provide the fundamental basis for
eGovernment service access.
For an example of ViewDS in action, see the ACT Government Directory
online. It can be found at: http://www.directory.act.gov.au.
eB2Bcom also currently provides the full 24x7x365 Australian Government
On Line discovery infrastructure solution. This encompasses an On-Line
Web based access service to the public at (www.directory.gov.au)
and an internal Identity Management infrastructure available to
all Federal Government employees.
ViewDS also handles changes to government organization (known as
CHOPLOC or Movement of Government Changes) with the ability to move
groups of staff, organizations or units easily between divisions
and departments.
Web based Identity Infrastructure update facilities are provided
to some 90 Departments and organizations allowing them to control
and update and provision new users, departments and organizations.
ViewDS also provides for full phonetic approximate matching which
is considerably superior to soundex. It can also perform various
other types of approximate matching such as synonym matching, the
recognition of spelling mistakes, The recognition of abbreviations
(e.g. IBM would match International Business Machines,) and perform
prefix matching (e.g. Fred would match Frederick.)
Governments require a solution that is fully X.500 and LDAPv3
compliant in order to ensure compatibility with other International
Government organizations, with compliance to the new XML enabled
Directory standard(www.xmled.info)
becoming more prevalent. They also require sub second response times
under extreme load.
Applications deployed within Government include service database/directories,
community services, XML applications for electronic business marketplaces,
telephone applications, supporting enterprise wide authentication
services and any customer facing application such as Provisioning
or User Self Service.

Meta Search Engine for AGLS and Green Pages
Green Pages are typically used within an Agency or Organization
to provide querying, browsing and viewing of standardized information
about document-like items. The availability of items is controlled
with some being made publicly available while others will have limited
distribution. The metadata information available identifies the
substance and summarized content of the document and provides details
on the location of the document with directions as to how to obtain
it. In general this capability is offered across an Intranet or
more practically through a publicly accessible Internet service
such as an e-Government service portal. In Australia this Metadata
on Government publications, so called Green Pages, is generally
structured so to conform to the Australian Government Locator Service
standards.
A Green Pages directory replaces assorted lists and databases in
agencies and incomplete information held centrally. This coupled
with a high speed search engine, user friendly access to Document
content using Component matching with the full support for XML Document
content as available in ViewDS provides an extremely versatile environment.
ViewDS can be deployed to draw together all the Government’s
metadata records providing access to the information from a central
government website. It can be linked to metadata published on individual
department websites. Users can then access a list of datasets by
attributes such as the location of an area of interest, geographic
extent and data theme. They can then preview the dataset selected,
examine the metadata for relevance and view the contact details
for the provider of the data. Access to the information is controlled
by access rights which will determine whether the user can have
direct access to the document itself by using a URI (Universal Resource
Indicator)
Whilst one of the key drivers behind the development of the “Green
Pages” directory is to facilitate the commercial and public
use of Public Service Information for economic and social purposes,
it is important to note that a whole-of-government PSI directory
can also be a very powerful tool for internal use within the public
sector.

eHealth Service Provider Directories
A directory of health services and providers referred to as a Health
Service Providers Directory (HSPD) has been identified as critical
core infrastructure by Health Departments. The need for a comprehensive,
trusted HSPD is driven firstly by the requirement of Departments
(and potentially the general population) to identify and contact
relevant service providers quickly and efficiently, particularly
in times of emergency. It is also an underpinning requirement for
any eHealth initiative such as electronic referrals and discharges
and when coupled with a national Patient Directory provides the
total identity infrastructure required for the “holy grail”
of the health industry, the Electronic Health Record.
A HSPD provides, or is the framework for, many Health initiatives.
These capabilities include:
• a web access point for consumers that will list all health
services and providers with authenticated access by authorized staff
to restricted data
• controlled interface to, or synchronization with, data of
other Departments, States, and National projects, such as Health
Connect and the National NEHTA initiatives.
• a core enabler for Electronic Referrals/Discharges
• storage of digital certificate keys for PKI based systems
such as secure email or two factor authentication
• Storage of trusted data of health professionals and other
parties for broadcast systems such as epidemics
• the basis for Electronic Health Record systems where the
interests and concerns of local health stakeholders can be reconciled
with national standards and requirements
• the location for a common provider list being used across
solutions to ensure consistent provider identification in referrals.
The benefits of a successful HSPD are:
• improved efficiencies in the search and selection of health
service provider information
• improvement in the quality of health service provider data
• improvement in the public’s perception of efficiency
in health service organizations
• improvement in access to health service provider information
• rationalization of the sources of health service provider
information
• reduction in the requirement for health service provider
information searches
• elimination of the need to perform multiple searches for
health service provider information
The technology used must meet the specific service needs of the
proposed users. This includes:
• high speed access
• integration with web services and the ability to store XML
data and more importantly to be able to search on its content
• high quality approximate matching, phonetic searching
• component matching (for more complex searches)
• hierarchical schemas to match departmental and hospital
structures
• facility for “machinery-of-government” changes
• strong authentication and support for protection of data
content to support State Privacy requirements
Inadequate “vanilla” database or LDAP technology in
general does not provide for these fundamental requirements (for
example the ability for simple “machinery-of-government changes”
to cope with the frequent re-organizations of departments, regions
and hospitals whereas ViewDS has all of these capabilities as standard
features.

eHealth - Hospital & Health Centre Directory Service
Within many hospitals and Health centres there is generally a major
frustration involved in finding accurate and up to date information
about staff, contractors, suppliers, and hospital appointments.
Like many similar organisations, hospitals are frustrated by their
multiplicity of data repositories for employees and contractors,
and the consequent lack of a single trusted authoritative source
of staff information. This lack of co-ordinated directory services
is seen as a major impediment to implementing other Identity Management
Systems, particularly for security and provisioning.
ViewDS for Hospitals known as HEARTS (Hospital Employee And Resource
Tracking & Searching) provides a hospital with a centralised
publishing point for staff, contractor, and visiting identity information
and single point of update for all Allied Health contact information.
It is the product of, and focal point for the integration, consolidation
and automation of Identity Management systems, processes and procedures.
HEARTS meets the requirements of multiple stakeholder groups supporting
them in the functions they perform.
It can also contain and publish other locally managed data for
which there is no other source. This could include:
• Non payroll staff - consultants, contractors, volunteers,
research students, etc.
• Functions and Roles - Duty Nurse, emergency reception, on-call
reception, etc.
• Resources (e.g. Meeting rooms) locations, booking details
and contact
• Committee groups - linkages of resources into
groups
• External contacts – information relating to external
stakeholders such as GPs, Health clinics and other Hospitals.
• Customised reporting such as Cost centre reporting and Employee
reporting
• Organisation charts
• Delegation Management
& Appointments Management
• Skills database including
User self service and competencies
• Emergency and first aid
• Location management (Floors, Buildings, cubicles, network
nodes linked to building plan layouts)
• PKI certificates
• External facing Health Portal, including self-service
Users are not always precise in searching a directory: names can
be mis-heard, transcribed incorrectly or shortened. Furthermore
there is a wide range of names from different languages. HEARTS
supports a range of approximate matching strategies to better support
searches by human users with an eHealth setting. These include:
• phonetic matching - e.g. "pane" will match "payne",
“wong” will also find “wang”
• typing correction - compensates for missing and transposed
characters e.g. “fisotheraphy” will match “physiotherapy”
• stem matching - e.g. "optics" will match "optical"
• synonym matching - e.g. "Bob" will match "Robert",
"road" will match "street", “Cancer”
will match “oncology”
• Abbreviation matching - e.g. "NSW" will match
"New South Wales"
• word matching, including word synonyms, word phonetic matching
and typing correction
• fuzzy logic used to rank and return
the best results and specialized indexes for rapid evaluation of
approximate matches on large databases
Access controls protect privacy and sensitive information from
inappropriate disclosure and provide a delegated administration
model allowing differing levels of update to be made by a number
of identified ‘Stakeholder’ groups. So Both Role Based
and Attribute Based Access controls are supported with fine grained
Access control based upon a combination of factors such as Time
of Day also possible. For instance the cost centre managers are
responsible for the accuracy and maintenance of information specific
to their staff within their cost centre.
HEARTS can leverage existing corporate systems and processes to
produce an up to date view of contact information. The regular automated
synchronisation of staff and organisational information provides
provisioning and de-provisioning of staff and automated maintenance
of the core Directory information. Corporate applications receive
a ‘copy’ of HEARTS information through automated synchronisation.
Examples are Windows Active Directory, Switchboard Interface, Finance,
Payroll and Contract Management, Call Accounting System, Administration
Systems and HMO systems.
Departmental phone listings and report are generated from the Staff
Directory providing real time information which can be presented
on the screen and printed on demand.
Entries in a directory are arranged in a hierarchy called the directory
information tree (DIT). The directory is most useful when the DIT
mirrors a real-world hierarchy e.g. the organizational structure
of a company or government which can be easily produced by just
selecting the Campus, department or Unit required. These reports
are generated automatically from the current information stored
in HEARTS.

eHealth - Master Patient Index
Within the Healthcare sector, one of the critical elements in delivering
quality healthcare is the eHealth Master Patient Index or eHMPI.
The eHealth Master Patient Index (eHMPI) cross references patient
identifiers across multiple information systems to uniquely identify
each patient, perform global patient searches and matching, and
consolidate duplicate patient records, allowing applications to
create complete views of patient information There are several advantages
to implementing an eHMPI system.
Some of the key advantages are:
• Consolidation of patient demographic information will enable
more informed clinical decision making.
• Seamless integration with existing departmental systems
to integrate files and IT systems that will provide a comprehensive
outlook of your information.
• Flexible data models and real-time capabilities will facilitate
improved record keeping and minimize overall costs.
eHMPI solutions can help by providing the following benefits:
• Improve patient care and safety.
• Increase provider satisfaction.
• Improve compliance capabilities with eHealth regulations
such as the US HIPAA and other regulations to protect patient privacy.
ViewDS Uses Advanced Matching Logic to help accurately identify
patients and avoid duplicate records.
The aim of the ViewDS as an eHMPI is to provide ability to link
acute and ambulatory data to provide an electronic medical record
with both demographic and encounter data from across the care continuum.
The aim is that no matter where an individual receives care, the
eHMPI can save registration and admissions personnel time at check-in
by giving them access to that person’s most current patient
index data. As patients move between care sites without having to
repeat their admissions data, they perceive the enterprise as a
single organization that recognizes them as individuals and understands
their healthcare needs.
When a new record is added to an eHMPI, unique, system-wide identification
number—called the Person Number—is generated for that
individual. A key component and important first step in creating
longitudinal patient records, the Person Number links external identifiers
demographic data, and encounter data records into a single data
set.
Today, a Person Number is frequently used to link a patient’s
records from interfaced clinical systems, such as radiology, pharmacy,
and laboratory.
When the Australian National Patient Identifier (ANPI) comes into
play, ViewDS implemented as an eHMPI can be adapted to link to that
identifier as well.
The Person Number benefits both users and information systems managers,
because current registration methods don’t have to be replaced
or a single medical record number format enforced across diverse
information systems.
Users can still locate patient information with the medical record
numbers or other permanent identifiers used on the organization’s
legacy systems.
Most important of all, ViewDS as an eHMPI makes it possible for
clinicians to identify and view in a single glance an entire medical
record from multiple encounters across the care continuum when linked
to a CCOW (Clinical Context Object work group) context management
solution such as Sentillion Vergence. Besides saving clinicians
both time and effort in locating records, ViewDS allows for easy
access to available data and the ability to share it with other
colleagues and facilities, which can help improve patient care and
delivery.
One of the key capabilities delivered by ViewDS is its advanced
matching capabilities. This advanced matching capability is designed
to provide an intelligently method of comparing a multitude of identity
attributes using a combination of heuristic matching and component
matching to:-
• Anticipate possible mistakes and variations
in data entry
• Match records even when their individual attributes
are not exactly the same
• Help overcome the inconsistencies
created by variations in registration practices across multiple
systems.
When a unique identifier, such as an enterprise identification
number or a facility ID/medical record combination, is not available
for a record search, ViewDS uses a set of heuristic matching algorithms
and indexes to examine and compare many different attribute fields
within the identity record in order to identify the correct match.
As part of ViewDS Administration a reporting module capability
is also available to help manage the user review of possible matches
and determine whether records should be merged.
Whenever the summary of an encounter (any inpatient or outpatient
visit with an admit date and billing number) is added to ViewDS
as an eMPI, it becomes part of the individual’s long-term
history. Each encounter is uniquely identified, so users always
have access to the data, regardless of the facility or department
in which the care was given. Additionally, this capability can be
used as a record locator service to facilitate queries of disparate
clinical systems to assemble a complete view of the clinical data
captured for a patient.
The ViewDS as an eHMPI can either operate on its own or as part
of a complete electronic medical record solution.
ViewDS fully supports either HL7v3 XML or openEHR XML.

Corporate Identity Server
A Directory is becoming an increasingly critical resource for the
provision of electronic services. The ability to easily locate the
information held within information systems greatly enhances the
efficiency of enterprises and individuals within that organization
particularly administrators who are faced with a myriad of different
proprietary information bases such as email address lists, EDI trading
information and human resources data.
Directory services that unify the mass of disparate directory information
within an enterprise enable users to simply and quickly locate information
they require. There is a particular challenge to integrate traditional
e-mail systems with the latest group-ware products so that companies
can communicate efficiently, regardless of the mechanisms used by
individual groups. This requires a corporate directory which publishes
e-mail addresses, functional information, and other attributes of
the employees. Access to the directory must then be enabled by a
variety of different means such as the Web, LDAP Client, Email address
book, LDAP Active-X, Java applications, WAP and SMS enabled GSM
and GPRS mobile data services.
The effective management of information is increasingly extending
outside the enterprise to include customers, suppliers and other
stakeholders. This requires an increased emphasis on security. The
proliferation of independent access and security administration
systems for networks, platforms and applications has impeded the
implementation of unified enterprise wide security policies. It
has created a massive security administration workload. It has also
created a considerable threat to the integrity of enterprise IT
infrastructure, and to the sensitive business information that IT
is chartered to protect. This need is driving rapid growth in the
use of directory services (such as ViewDS) as a repository for all
identity information to provide a robust and scalable infrastructure
to underpin access to the enterprises information. This allows the
enterprise to derive competitive advantage through better access
to global customer information and corporate personnel information.

Corporate Telecommunications Directory
ViewDS has been deployed into a number of organizations as a basis
for their White Pages telecommunications directory service. ViewDS
also provides a range of searching tools which vastly simplifies
and streamlines end user access to Directory content. These include
approximate matching on a search request, including phonetic matching
and spelling correction, truncation matching, abbreviations, keyword
matching, synonyms, and combinations of these.
ViewDS has also been integrated into existing PABX phone environments
with a number of existing customers using the PABX Address book
server to either do a real time LDAP search on the directory and
display its results to the phone user, or via a nightly update process,
synchronize its internal records with the directory content.
The directory can be fully integrated with the PABX workstation.
As an example a large NSW Government Agency has deployed ViewDS
integrated with MSAC consoles from T-Metrics.
These consoles integrate with the phone system and allow automatic
call establishment. Phone numbers from the directory are made available
to the device via the ViewDS WebDUA. Its templating capability is
used to add XML-like tags around the phone numbers. This results
in active links in the browser which, when clicked, is picked up
by the toolbar and used by the console device to dial the selected
number.

XML Document and Information Store
ViewDS provides support for XED, allowing it to offer a variety
of XML services that other LDAP Directories cannot provide. With
ViewDS, you have the ability to store, query and retrieve XML documents
using standard LDAP operations. Since the XML content is intelligently
understood, advanced searching capabilities are supported by ViewDS.
The example below indicates how ViewDS can be used in conjunction
with the third party technologies, BMC Identity Management Suite
and the IBM Lotus XDFL Forms. In this case the BMC Identity Management
suite is providing a web interface into the ViewDS directory. IBM
Lotusforms are being stored within the directory in their native
XDFL format. ViewDS is being used to intelligently process the data
within the IBM form to respond to search operations.
Searches based on text fields within XML documents can be completed
via a web interface. The web interface (BMC) will simply send ViewDS
an LDAP search operation. ViewDS will target the appropriate section
of the IBM form and apply search there.
Search operations are not only limited to text fields. In this
example, the web interface is asking if a specific ‘checkbox’
within the form has been ticked. Using normal LDAP operations,
ViewDS is able to identify the checkbox in question and respond
authoritatively.

Postal Authorities
Many Postal Authorities can no longer depend
on their traditional business services and are seeking to diversify
their business to encompass new services. By deploying ViewDS
Identity Management server, Postal Authorities will be able to:
• Develop new profitable e-Postal services by diversifying
from traditional services
- Add value to existing services Electronic bill payment
services
- National email registry
- Digital Certificate Authority services
• Offer Secure messaging services

Airlines
Airlines have a requirement to provide fast and secure access to
their information and services via the web, for staff, domestic
and international customers and alliance partner members. Such an
environment can result in a directory containing millions of entries.
ViewDS’s scalability and reliability, compliance with the
ITU X.500 standard and support for both DAP and LDAP protocols makes
it an ideal platform for airlines.

Education
An Australian State Education Department required a web-based electronic
directory, accessible state-wide by all staff over the Department's Intranet.
ViewDS Directory was selected as the core product.
A web-based blue page and white pages search capability has been interfaced to
the directory. The directory is maintained and updated automatically directly from
the various departmental payroll and personnel systems. The hierarchical database
structure provides for work-flow routing and sub-tree based access control groups.
This has allowed the directory to be leveraged for a range of other cooperative business
processing application developments.
One application is a web based electronic leave system, which allows staff members to
remotely logon to the Department's web portal and lodge a leave application.
The leave system uses the logon authentication details to locate the person within the
directory unit structure and each unit has a link to the Manager/Senior Officer of the unit.
The person assigned as Manager/Senior Officer has leave approval rights for that unit or any
subsidiary units. The unit may contain an organisational role entry with one or more occupants with
leave approval rights for that unit only.
For units identified as schools the automatic staff maintenance procedures from HR/Payroll
automatically maintain the Senior Officer/Manager attribute for movements of Principals into
or out of the school.
The leave system checks the staff member's unit for links to Managers or Leave approvers;
if a link exists the system reads the approver's entry for their email address and sends an
email advice that a leave application form needs approval.
If there is no Manager/Senior Officer or leave approver nominated for that unit then the
leave system will work up the hierarchical unit tree structure to find the next superior unit
with a nominated Manager/Senior Officer to receive the email advice.
A web based on-line transfer system also uses the directory to identify the Principal/Senior
Officer of a school in order to receive electronic transfer applications for teachers based at
that school.
The definition of workgroups within organisational units and the linkage of staff as members
of those workgroups is an important structure used by a number of cooperative systems in determining
the level of systems access a user may be provided.
For instance there is an internet based facility for members of the public who have appropriate
recognised qualifications to search for jobs within the Department. The job seekers can prepare and
submit a job application electronically. Staff within the department who process applications have
access levels determined by their membership of an appropriate directory workgroup.
For instance membership of one group would give a user access to teacher applications whereas
membership of subset would allow the review school administration staff applications. Another
nominated group would be required before a user could post job advertisements onto the repository.
Distinguished Name links to managers, organisational roles, group memberships etc are automatically
updated if units are moved or renamed. Similarly, the system provides for these links to be automatically
removed if the staff member is moved to another unit.
The directory has also been directly interfaced with telephony systems which provide switchboard
functionality across the department's state office locations. This interface allows person/unit search
and auto-dial capability to the switchboard operators.
The reliance on the directory solution by staff and developed applications, has made the central
directory an essential enabling technology and integrated business solution.
The Department has implemented an infrastructure upgrade to redundant Directory servicing. This has
been accomplished by using the Master-Shadow replication implemented within ViewDS. In the event of a
system failure, the shadow directory can be enabled as a master directory providing fail-over
functionality.

Banking and Finance
Customer high speed access is paramount when delivering eBanking
services.
Banks today are developing an enviable but challenging e-business
problem. Their new online banking systems are becoming tremendously
successful resulting in a skyrocketing number of Internet banking
customers.
The Banking and Finance sector use directories to support global
communications and e-commerce. They form the basis of a cost-effective
infrastructure for compiling, distributing, managing and securing
information in a cost-effective way which is crucial to their market
competitiveness.
ViewDS is a high-performance directory server. It can handle hundreds
of millions of entries while maintaining performance, reliability,
security and ease of use. Furthermore, by using Express Sync conversion
tools, data can be imported from various external repositories into
the Banking Directory server. This scalability and flexibility is
essential in a deployment where the number of entries can climb
into the millions.

Support of Aviation Messaging
AMHS (Air Traffic Services Message Handling Services), as specified
in the ICAO ATN (Aeronautical Telecommunications Network), is the
new standard for ground to ground messaging communications in the
Aviation sector. The new AMHS specification requires an ATN Directory
Service that is essential for the deployment of many of the services
defined in AMHS. The ATN directory is based on the ITU X.500 specification,
which is extended for various ATN capabilities. X.500 was originally
designed by the ITU-T to support the global telecommunications systems,
and so is ideal for the ATN application. Key elements of X.500 are:
• Hierarchical Naming. This allows authority to be naturally
delegated to ATN participants, and to allow distributed deployment
that follows the same hierarchy.
• Distributed and replicated directory provision, using
multiple DSAs (Directory System Agents); this makes ViewDS the
perfect platform for supporting a widely distributed system such
as ATN.
• Extensible schema. This extensibility has been used effectively
in the ATN directory to extend the core X.500 schema to provide
ATN specific functionality. This extensibility can also be used
by ATN Directory vendors and customers to add further specific
functionality.
• Standardized access protocols, enabling client/server
management, and easy integration into ATN applications.
ViewDS supports the new ATN Directory requirements of AMHS.
