Poscast from Richard Cyganiak

This poscast is a chat with Richard Cyganiak, who’s currently working on the Sindice Semantic Web search engine at DERI (the biggest think tank of the SW), though is probably best known for his leading role in the Linking Open Data project (maintaining the cloud diagram and D2RQ.

In the podcast Richard describes various technical details of these projects, and talks about the nature of data on the Web in the wild, as RDF, microformats and increasingly RDFa. He also discusses some of the practical issues in mapping existing databases to the Semantic Web (the kind of techniques Tim Berners-Lee mentioned in his podcast with Paul a few weeks ago).

Richard naturally mentions the principles of Linked Data :

1. Use URIs as names for things
2. Use HTTP URIs so that people can look up those names.
3. When someone looks up a URI, provide useful information.
4. Include links to other URIs. so that they can discover more things.
