1. Background

• KM.Gov Discussion of Business Function Models
  (Denise Bedford, May 26, 2004)
• The World Banks 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!

1. Background

• 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.)

See GCN, May 20, 2004, Forman calls for new
approach to the Federal Enterprise Architecture.

1. Background

• Nationwide Infrastructure for Community
  Statistics Community of Practice (NICS CoP), May
  27, and July 1, 2004, The Brookings Institution
• Nationwide Systems
• E.g., Marshall DeBerry, Bureau of Justice
  Statistics and Interagency Council on Statistical
  Policy, FedStats
• Statistical System Tools and Technologies
• E.g., Joe Ferreira, Department of Urban Studies
  and Planning, Massachusetts Institute of
  Technology, Intelligent Middleware and Virtual
  Data Repositories
• Data Providers, Users, and Local Intermediaries
• E.g., Tom Kingsley, Urban Institute, National
  Neighborhood Indicators Partnership

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
  Bureaus 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
Content gives us the semantics
(taxonomy/ontology) the interoperability, Adam
Pease, SICoP Meeting at MITRE, May 19,
2004. Structure comes from the content
itself, The Large Document Problem, Lucian

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).
