DRM 3.0 Architecture Suggestions Highlights

• Data Description:– Uniform Resource Identifiers (URI)

• Data Context:– Taxonomy/Ontology:

• Information: Topic and Subtopic• Data: Data Table and Data Elements• Information and Data Modeling: Build on David Hay’s Work

• Data Sharing:– Data and Metadata “Travel Together”

Note: These have been implemented in a Web 2.0 Wiki at http://federaldata.wik.is

Suggestions for the Federal Enterprise Architecture Program

Item Suggestion Action

FEA Segment Architecture Methodology (FSAM)

Decompose Segments into Patterns

SOA for E-Gov Conference

(see next slide)

Recovery.gov Public wants raw data and tools

Web 2.0/3.0 pilots initiated

Data.gov Use Statistical Abstract Staff

Suggestions for the FEA Data.gov Program

Data.gov epadata.wik.is* CommentsCIO proposes Open to all Supports

transparency, openness, & collaboration.

Raw Value-Added Should do both.

FGDC Metadata Standard

Statistical Abstract Table Metadata

Much simpler-only 7 elements versus many more.

GSA Cloud Computing

Mindtouch/Amazon Web 2.0/3.0 Cloud Computing

Free or very low cost.

Interagency Working Group on Digital Data

• The National Science and Technology Council (NSTC) released a report describing a strategy to promote preservation and access to digital scientific data. The report, Harnessing the Power of Digital Data for Science and Society, was produced by the NSTC's Committee on Science under the auspices of the Office of Science and Technology Policy (OSTP) in the Executive Office of the President by the IWGDD.– See
