EKB Goals Management, Integration & Analysis of Enterprise

Architectural, Systems, Metadata and Governance Information Authored and managed by multiple authorities Using different tools, models, diagrams, standards,

paradigms and formats Presented in user-friendly views appropriate to the role and

task Provisioned to tools & technologies for execution Federated across the Enterprise, Government and Supply

There is no one enterprise view! What is King?

Information & Data Services (SOA) Process (BPM) Finances Rules Goals Governance Systems Design Organizational Structure

Yes

Every one, and more, arepart of the Enterprise

and Systems Architectures

But none of them can stand alone

A solution must integrate information, while providing the view of that informationappropriate to each stakeholder


The “Meta Muddle” There are hundreds of “meta models”, tools, diagrams and exchange formats, all

associated with our business architectures, solution architectures and systems implementations.

These are “stovepiped”, and not designed to work together. Users struggle to keep different views of the same thing and related things coherent

and consistent The result is an error prone, expensive and ineffective process for managing our

information assets and system implementations. Business and systems goals and requirements are not integrated and thus not fully

realized. Information defined in a “foreign” format, tool or methodology is frequently lost,

inconsistent or manually synchronized. Each new standard or proprietary product is just another stovepipe. Different contractors and technologies introduce more of the same, or proprietary ways

to integrate information that attempt to lock the enterprise into a single vendor’s solution.

EKB Approach


Three layers of solution Dynamic Configuration Management of Artifacts

Understand where all of your information artifacts are, where and who they came from and how they evolved over time (Based on Subversion and Provenance)

Structured Information & Metadata Management Get all of your models, forms, requirements and other structured

information into a common form that can be analyzed and federated (Based on the Shared Web)

Integration of Information through Shared Concepts Understand how information in multiple forms, tools, standards and

methodologies is related and mutually supportive (Based on Ontologies and standards from the OMG, W3C and Oasis)

Managing Change & Provenance

Enterprise knowledge must be trusted and managed.

The source and authority of each fact in the knowledge base is traceable to the “speech act” of some individual at a particular time.

Licensing The EKB is an open source project

https://sourceforge.net/projects/enterpisekb Not announced yet

Licensed as “GPL” Free for open source and internal use Licensed for commercial use

Initially funded as part of a U.S. Government project of the G.S.A (osera.gov)

Planned as commercial open source under ModelDriven.org

https://sourceforge.net/projects/enterpisekb


Status The EKB is a prototype implementation aimed at Government requirements,

but is not government specific The prototype release is planned for the end of August, 2008 All of the functionality mentioned will demonstratable in this release, with the

exception of a dynamic Eclipse-EMF API & Rule support. Model synchronization is not yet bi-directional.

Current model support includes: XSD, BPMN, UML (partial), EDOC & RDFS Our goal is to create a pervasive and open knowledge management

platform Both commercial and open source tools will plug into this platform Next stage is to plan and execute a production version ModelDriven.org plans to develop to a commercial open source product with

partners


Opportunities Enable better integration of architectural and governance

information for our enterprise customers Open and pervasive governance and metadata platform throughout

the government and large organizations Enabling communities and virtual organizations SOA & BPM Governance Better execution of architecture and implementation projects Products and services that leverage and build on the core repository

capabilities Solve our own problems with multiple tools, standards and

methodologies.
