DownScale2014 and OpenDevelopmentCamp

Dear everyone,

This is a short post to invite you to come to two open development related events on the 8th, 9th and 10th of October 2014 in Amsterdam:

  • October 8th: “Downscale2014“, the third edition of the workshop on downscaling the semantic web. This is a free event organised by the team at WorldWideSemanticWeb. The program will be built during the coming weeks from input proposed by the participants. The outcome of this day will be presented during ODC.
  • October 9th and 10th: “OpenDevelopmentCamp (ODC)”, is the 4th edition of a forum for discussion organised by the people from Open For Change. The program is already packed with great keynote speakers and the event has the support of major development related organisations.

We hope you’ll be able to attend these events and look forward too seeing many of you in Amsterdam soon! :-)

Here is result, with a cleaner and simpler interface and a brand new logo:

The DLD community is listed on the contact page:

and some of the data output is listed on the data page:

We hope you’ll enjoy it and we’re looking forward to your feedback. As for any website, the hardest part is to get more content in so don’t hesitate to ping me if you want to get edits rights to help filling up the pages.

SPARQL Reasoning Using An Aligned Ontology In Jena

If I have an aligned ontology in my hand that corresponds to a RDF graph in Jena, how can I issue SPARQL query to the RDF store through Jena such that inferences will be made with respect to the supplied ontology?(i.e my ontology file and RDF files are seperate, but I would like to use the knowledge in ontology for any SPARQL queries issued through Jena)
