  5. 5. LOD Definition URI (Uniform Resource Identifier) URL (locator) URN (name)
  6. 6. LOD Definition Tim Berners Lee’s 4 Rules 1. Use URIs to denote things. 2. Use HTTP URIs so that these things can be referred to and looked up ("dereferenced") by people and user agents. 3. Provide useful information about the thing when its URI is dereferenced, leveraging standards such as RDF, SPARQL. 4. Include links to other related things (using their URIs) when publishing data on the Web.

  8. 8. LOD Star ☆ Publish data on the Web in any format (e.g., PDF, JPEG) accompanied by an explicit Open License (expression of rights). ☆☆ Publish structured data on the Web in a machine-readable format (e.g., XML EXCEL). ☆☆☆ Publish structured data on the Web in a documented, non-proprietary data format (e.g., CSV, KML). ☆☆☆☆ Publish structured data on the Web as RDF (eg Turtle, RDFa, JSON-LD, SPARQL) ☆☆☆☆☆ In your RDF, have the identifiers be links (URLs) to useful data sources.

  21. 21. Semantic Web - Purpose Find, Share, and Combine information more easily. The semantic web is a vision of information that can be readily interpreted by machines Machines can perform more of the tedious work involved in finding, combining, and acting upon information on the web
  22. 22. Semantic Web - Difference
  23. 23. 3. Conclusion Machine readable Links to your data and search engine indices can increase the visibility of your data Structured data can be interlinked and become more useful
