If you are interested in open data, at some point, it leads you to Linked data. And Linked data inevitably leads you to the Semantic web. And in the core of the Semantic web lies the DBpedia which is currently being challenged by Wikidata project.
At the Baltic Open (Geo)Data Hackathon, I hope to find use case examples for spatial data in DBpedia and Wikidata databases, and on the other hand help solving respective issues with RDF and with examples how to use these databases.
