EKBIntro Presentation Transcript

  • 1. Enterprise Knowledge Base Integrated knowledge for and about the enterprise EKB Cory Casanave, President Model Driven Solutions Cory-c (at) ModelDriven.com July 2008
  • 2. 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 Chain
  • 3. Business Focused Architected Solutions Business Concerns Goals Policy Customers Costs Agility Technology Specification JMS, JEE, Web Services WSDL, BPEL, XML Schema Logical Systems Architecture Technology Services (t-SOA), Components, Process Execution Interfaces, Messages & Data Business Architecture Enterprise Services (e-SOA) Roles, Collaborations & Interactions Business Process & Information Refinement & Automation Line-Of-Sight Computation Independent Model Platform Independent Model Platform Specific Model MDA Terms
  • 4. Value derived from the architecture Component Acquisition Specification Technology Interfaces Test & Simulation OMB 300 FEA/FTF BRM SRM DRM TRM Business Driven Technology Facilitating Business Processes Adapters Components Data Deployment
  • 5. 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, are part of the Enterprise and Systems Architectures But none of them can stand alone A solution must integrate information, while providing the view of that information appropriate to each stakeholder
  • 6. 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.
  • 7. EKB Approach
  • 8. 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)

    • Library of Concepts
    • Growing based on need
    • Modular, not monolithic
    • A construction set for languages
    • A lattice of interoperable concepts
  • 13. “ Views” of Integrated Information EKB Shared Concepts UML DoDAF BPMN Ontologies FEA Requirements EDOC XML SQL OWL E/R Models Security Projection Projection * Conceptual - Not all of these models are implemented! Provision Web Services Java/J2EE Workflow Documentation Legacy BPEL
  • 14. 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.
    Knowledge Base Data Asset Version Version Version Version Version Speech Act Speech Act Speech Act Speech Act Speech Act What is stated by a particular authority at a particular time with respect to a particular data resource A view of the data resource at a particular point in time informed by a authorized set of speech acts A managed set of information, I.E. “A process kodel” “ Head” version – is up to date
  • 15. Base Technologies & Standards
    • Eclipse with EMF (Eclipse Modeling Framework) and UML-2
    • RDF & OWL Using Sesame ( www.openrdf.org )
    • Subversion configuration management ( http://subversion.tigris.org/ )
    • Orbeon xForms ( http://www.orbeon.com/ )
    • Intalio BPMN ( http:// www.intalio.com / )
      • BPDM / BPMN-2 Support planned
    • Magicdraw UML
    • OMG - UML, MOF, XMI, EDOC, BPMN (BPDM & IMM Planned)
    • W3C “Semantic Web: - RDF, RDFS, OWL
    • Tomcat using REST
    • XML Stack (XSD, XSLT…)
  • 16. 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
  • 17. 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
  • 18. 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.
