Time to raise a red flag

Too many applications are being built with proprietary structures that are non-interoperable

Too many duplications Everyone is busy mapping across islands using

at best databases, and XML, but at worst documents and spreadsheets

The potential of the FEA is not being realized Semantic Web Technology is here and is

designed to solve these problems Why are people in US Government Agencies

not using Semantic Web Technology?


TopQuadrant

Progress on FEA Ontology-Based Solutions

TopQuadrant proposed an FEA Capabilities Manager in early 2003 with an FEA Ontology Model – as a Pilot

We have now developed, with some GSA funding, a validated FEA Reference Model Ontology, called FEA-RMO

Using FEA-RMO, with other ontologies, we have built a 2nd generation FEA Capabilities Manager

An example of how Semantic Technology is enabling new kinds of collaborative environments

Opportunities for More Collaboration*?

* Urgent Business for America: Revitalizing the Federal Government for the 21st Century. The Report of the National Commission on the Public Service, January 2003.

50 agencies implement Federal drug control strategies

29 agencies administer 541 clean air, water, and waste programs

23 agencies administer 200 programs to assist countries formerly part of the Soviet Union

13 agencies administer 342 Federal economic development-related programs

12 agencies administer more than 35 food safety laws

11 agencies administer 90 early childhood programs

9 agencies administer 86 teacher training programs

9 agencies administer 27 teen pregnancy programs

8 agencies administer 50 different programs to aid the homeless

TopQuadrantOntology Lifecycle Management Environments - COVE and TopBraid respond to the need:

“How can I deploy simple web forms to my team” “How can I manage and version control multiple

ontologies” “How can I administer who can contribute data to

our ontologies” “How can I move concepts between name spaces

and propagate the change to all dependent ontologies”

“How can I manage the provenance of who contributed what”

TopQuadrantOntology Focus at NASA for the next manned missions:

Key Issues: The Next Space Exploration Programs will have

heterogeneous information sources and the need for integrated processes

Decision support for these programs involves trade-off analysis across multiple disciplines with rationale capture and impact analysis

Complicating Factors Geographically dispersed workgroups Different organizations: contracts determine information

sharing behaviorConsequence

Complicates supporting effective organizational learning and systematic infusion of safety system knowledge into design and operations planning and processes

Ontology Approach to Enterprise Architecture

Bridges the gaps between business, technology and IT

Makes Value Nets “Navigate-able”

Makes Capabilities “Knowledge-able”

Makes Components “Knowledge-able”

Uses Semantic-Enabled Collaborative Tools

Component knows:where it is used, how it is realized, what it depends on,its measures of effectiveness

Knowledge Model using Semantic TechnologyBehavior Model for inferencingFederated ArchitectureAnalytical ToolsDecision Support

Capability knows:why it exists,what enterprise activities need it used, what it depends on, its measures of effectiveness

“Line of Sight” across:extended enterprise business unitswithin business unitsto measures of effectiveness

“Connects the dots” across:Business, technology and IT models

The “Call to Action”

The Promise of Semantic Interoperability is here

$Millions is spent on inadequate systems Semantic Technology works today Promise of “Integrated Collaborative

Government” is not being realized A proof of concept has been built – the first

operational system will be inexpensive - and will offer substantial ROI

How can we pave the way to the fulfillment of interoperable Government?
