Dimitri van Hees, Technical Architect/Data Specialist, Freshheads BV Learn how one organization put Linked Data to work for it by adding a sixth star --- using APIs --- to Sir Tim Berners-Lee’s 5-Star Scale for implementing Linked Open Data. This session includes an introduction to Linked Open Data, Linked Closed Data, and Berners-Lee's 5 star scale and do a step-by-step walk-through of a successful implementation. It will include a frank discussion regarding the technical and organizational challenges encountered with a real-world Linked Data project and how those challenges were overcome. In this session, you will not only learn how to think about Linked Data APIs in real world terms, but also how to "sell" it to the organization." If you are attending this presentation, you may also want to attend Markus Lanthaler's presentation on Why and How to Optimize Your Data Architecture for an Integrated Future.
