Will linked data on data.gov.uk survive an election?

Last week I attended a cross-political party dinner given by the Technology Strategy Board(TSB) to promote their Digital Britain programme to policy-makers. There were about 20 of us there – mostly politicians, a number of people from the TSB and a few people from industry. Epimorphics is currently working on two TSB (part-)funded feasibility studies…

An RDF to JSON converter on Google App Engine

As part of our work on the SDX project we felt one requirement was to enable typical web developers to exploit the RDF linked data in a simpler, more developer friendly form. In particular it would be nice to be able to access an RDF model of a resource as JSON to simply using it…

RDF Result sets

In some recent semantic web applications, where we’ve been creating user interfaces over REST style interfaces over RDF data sets, we found a common pattern emerging – ResultSets. The approach we took has been documented but it’s buried in other details so I’d like to pull out the essential pattern in this post. Situation The…

Investigating VoID and CKAN

For some experiments we’re doing at the moment, I need some datasets from CKAN that also include VoID markup. Fortunately, the metadata from CKAN has been translated to RDF: there’s no official reference that I can find, but this thread describes the main points. Sadly, the CKAN RDF does not include any elements from VoID….
