[okfn-help] Fwd: New LOD group + CKAN in RDF

[David Read]

It's great to have all this interest in the CKAN RDF! I'll try and
answer the latest questions here.

>Will you provide some sparql examples in the future.

Here's a sample SPARQL query for the CKAN store, showing packages with
the 'health' tag:

PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX dc: <http://purl.org/dc/terms/>
SELECT ?name ?subject
WHERE
 { ?x foaf:isPrimaryTopicOf ?name .
   ?x dc:subject "health" }

My previous post gives a de-referencable URI for the records in the
store -  is this what you're after? Do let us know what you are trying
to achieve with it and maybe we can help more?

> Also, do you plan to embed RDFa in your HTML pages?
Yes, it's an existing ticket - we will aim to get it done soon.

All the best,
David Read
