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

  7. 7. TimBL’s 5-star plan for open data<br />★ Make your data available on the Web under an open license<br />★★ Make it available as structured data(e.g., an Excel sheet instead of image scan of a table) <br />★★★ Use a non-proprietary format(e.g., a CSV file instead of an Excel sheet) <br />★★★★ Use linked data format(i.e., URIs to identify things, and RDF to represent data)<br />★★★★★ Link your data to other people’s data to provide context<br />Source: http://inkdroid.org/journal/2010/06/04/the-5-stars-of-open-linked-data/<br />
  8. 8. Government data catalogs<br />http://datos.fundacionctic.org/sandbox/catalog/map<br />
  9. 9. The fourth star<br />★★★★ Use linked data format(i.e., URIs to identify things, and RDF to represent data)<br />From “document/report” thinking to web thinking<br />What are the “things” your organization manages?<br />Assign identifiers (http:// URIs)<br />Make “things” web-addressable<br />
  10. 10. The fifth star<br />★★★★★ Link your data to other people’s data to provide context<br />Standardization/alignment/harmonization between data produced by different organizations<br />Connect to standard identifiers<br />Use standard schemas to describe things (e.g., a person)<br />Linking and mapping can happen up-front or after the fact<br />Basics can be widely standardized and combined with specific local schemas and IDs<br />
