  • 3. Linked Data Principles
    Use URIs to identify the “things” in your data
    Use http:// URIs so people (and machines) can look them up on the web
    When a URI is looked up, return a description of the thing (in RDF format)
    Include links to related things
  • 4. Linked Data example

  • 5. The Growth by Domain 2009-2010
  • 6. Doubles every 10 months
  • 7. TimBL’s 5-star plan for open data
    ★ Make your data available on the Web under an open license
    ★★ Make it available as structured data(e.g., an Excel sheet instead of image scan of a table)
    ★★★ Use a non-proprietary format(e.g., a CSV file instead of an Excel sheet)
    ★★★★ Use linked data format(i.e., URIs to identify things, and RDF to represent data)
    ★★★★★ Link your data to other people’s data to provide context

  • 9. The fourth star
    ★★★★ Use linked data format(i.e., URIs to identify things, and RDF to represent data)
    From “document/report” thinking to web thinking
    What are the “things” your organization manages?
    Assign identifiers (http:// URIs)
    Make “things” web-addressable
  • 10. The fifth star
    ★★★★★ Link your data to other people’s data to provide context
    Standardization/alignment/harmonization between data produced by different organizations
    Connect to standard identifiers
    Use standard schemas to describe things (e.g., a person)
    Linking and mapping can happen up-front or after the fact
    Basics can be widely standardized and combined with specific local schemas and IDs
