1. DRM Working Group Status

• 1.1 August 22nd Meeting
• DRM Pilot Presentation by Digital Harbor
• What the DRM can/should be (Michael Daconta)!
• Business Ontology supports the DRM Abstract
  Model.
• DRM Version 1.5 Overview Chapter (see next
  slide)
• Working Group suggestions for clarity.
• SICoP Needs better organization, even a model
  (ontology) for the document, the reference model
  itself, and for applications (see slides 5 and
  6).
• DRM Examples Recreation.gov
• Provided Guided Tour of the Recreation.gov DRM
  XML Instance.
• Abstract Model
• UNISYS says they have a utility based on a MOF
  repository that automatically generates DRM XML
  Schema Instances from UML Class Models created in
  commercial tools (e.g. Rationale Rose, Popkin
  System Architect, ProVision, etc.) and can also
  publish as an XTM Topic Map or OWL Ontology (for
  Structured Data Only). See slides 7 and 8.

1. DRM Working Group Status

• 1.2 SICoP Objectives
• SICoP needs to provide the Semantic Technology
  Profile for the Data Reference Model (DRM).
• SICoP needs to provide the parts of the Module 3
  White Paper Implementing the Semantic Web that
  relate to the DRM.
• 1.2 SICoP Phases (recall slide 6)
• Phase 1 Taxonomy Information Sharing Tool Kit
  Part 1 SVG (June 28 and September 14).
• Phase 2 Metadata Interoperability Information
  Sharing Tool Kit Part 2 RDF (August 16).
• Phase 3 Executable Data Interoperability
  Information Sharing Tool Kit Part 3 Ontology
  (June 13 and September 14).

Note Phase 1 was based on the EPA Region 4 Pilot
Work!

2. EPA DRM Status

• 2.1 DRM Water Resources Use Case in Composite
  Application Platform
• Use Case 3 Demonstrating the maturity of FEA for
  multi-agency and community-of-interest
  information sharing and issue analysis.
• This use case demonstrates how semantic models
  (ontology) can provide a framework for data
  interoperability where similar datasets need to
  be combined to support an aggregated business
  context for tactical decision making, analysis,
  and policy making across multiple communities of
  interest.

2. EPA DRM Status

• 2.1 DRM Water Resources Use Case in Composite
  Application Platform (continued)
• The FEA Business Reference Model provides a
  framework that facilitates a functional (rather
  than organizational) view of the federal
  governments lines of business (LoBs),
  independent of the agencies, bureaus and offices
  that perform them.
• This pilot focuses on the specific business
  function Environmental Monitoring and Forecasting
  (1-108-023). The end Use Case is to provide an
  interactive Composite Report on the Environment
  (EPA ROE 2006) that combines data about water
  indicators from a number of agencies into a
  coherent picture reflecting the status of
  nations waters in the social, economic and
  environmental context.

2. EPA DRM Status

• 2.1 DRM Water Resources Use Case in Composite
  Application Platform (continued)
• Recently started, the pilot will illustrate how
  indicator ontology can be created for water that
  uses ontological relationships to relate
  different indicators based on their properties,
  use and the type and quality of impact. The
  ontology can then be used to drive an interactive
  report that supports seamless navigation across
  the indicators and their cumulative impact on a
  particular area of concern.

  Word and PNG and added semantic structure linking
  (see next slide).
• Extract the water data sources URL and documents
  for data mining by the Digital Harbor PiiE

  were analyzed and assigned to three basic
  categories and 14 sub-categories (see next slide).

  EPA content and interoperability with non-EPA
  content.
