Multi-Agent and Semantic Web Systems: Linked Open Data

This slide presentation of lecture material was used as part of a course given at The University of Edinburgh School of Informatics. This lecture looked at a wide variety of topics, focusing in particular on Linked Open Data principles for publishing data, the purpose of using URIs, and content negotiation.

  - Identity in RDF
    - Understands that a "real-world" thing may need to be named with a URI distinct from the URI for information about that thing.
Knows the "five stars" of Open Data: put data on the Web, preferably in a structured and preferably non-proprietary format, using URIs to name things, and link to other data.
