                  1. Background
• KM.Gov Discussion of Business Function
  Models (Denise Bedford, May 26, 2004):
  – The World Bank‟s is a narrow and deep hierarchy:
     •   Level 1 = General Business Area
     •   Level 2 = Business Activity
     •   Level 3 = Business Process
     •   Level 4 = Task
          – Note: A „service taxonomy‟ is an inherent part of a business
            taxonomy and emerges at Level 3 and below. If you can keep
            business function and organizational unit as separate
            attributes, you can then see which organizational units may be
            offering the same kinds of services and this might help to form
            communities of practice across organizational units!

    • Fourth Quarterly Emerging Technology
      Components Conference: An Emerging Public-
      Private Partnership at MITRE, June 3, 2004:
         – Some recommendations on Strategic Directions:
              • Involve taxonomy (ontology) expertise in improving the FEA
                classification scheme (taxonomy) and its extension into the
                agencies. (This should also help the Line of Business Task
                Forces work.)
              • Involve knowledge management expertise in building a
                comprehensive knowledge-base (repository) of enterprise
                architecture (OMB budget, solutions like Service-Oriented,
                Web Services, etc.)

               1. Background
• NICS CoP Pilot Paradigm:
  – The Document (structured) Is the Interface to the
    Data and Metadata!
• Some NICS CoP Pilot Requirements:
  – “Low-cost Re-purposing” (Cavin Capps, Census
    Bureau‟s Data Web).
  – Author Once-Disseminate Many (Print, Web, and CD-
    DVD).
  – “Live Publishing” (fast and easy to edit and add
    content).
  – Incorporate the taxonomy, ontology, and registry
    (harmonization-standardization) within the document
    (see next slide).

                1. Background
• Some important features of the mapping
  matrices (slides 9-10):
  – The Conceptual Areas (Nodes)/ Knowledge Objects
    (Services) consist of XML information objects which
    can be reused in different contexts, applications,
    Communities of Practice, etc.
  – The reuse is accomplished through:
     • Metadata;
     • Taxonomies (even Ontologies); and
     • Standardization/Harmonization (mappings between and
       across) Across Multiple Taxonomies (even Ontologies).
