Dr. Axel Polleres
Using/Extending RIF and SPARQL to navigate Linked Open Data?
In this talk we will instroduce two standards - SPARQL and RIF - to formulate rules and queries for creating simple mashups to access and extract Linked Open Data on the Semantic Web. The presenter was/is involved in the shaping of these two standards within the W3C and works on implementations and several extensions of both. Base concepts of the languages and what you can do with them will be introduces by practical examples and - time allowed - accompanied by some demos.
