1.       Get concept (all triples with concept as subject or object - DESCRIBE) with prefLabel = "foo"

2.       Get concept with prefLabel in Fonglish = "foo"

3.       Get concept http://example.org/bar and all narrower concepts

4.       Get concept http://example.org/bar and all broader concepts

5.       Get concept with prefLabel in Fonglish = "foo" and all narrower concepts

6.       Etc ...
i.e. pre-rolled queries which use the SKOS properties.

Reusable SPARQL queries might be part of a solution.

What aspects of SPARQL would such a standard layer include? We and our customers are heavily using SPARQL in the context of SKOS, and we have published a SPARQL-based constraint checking library [1] using the W3C Member Submission SPIN [2]. This will validate the various SKOS-specific integrity constraints and has been integrated with TopQuadrant's Enterprise Vocabulary Net (EVN) solution [3].

SPIN also makes it easy to encapsulate reusable SPARQL queries into so-called templates. These templates are basically parameterized queries that have a URI and arguments. Compare to stored procedures in SQL. It would be straight-forward to build and publish such a template library for SKOS, if someone here has a list of queries that they like to ask repeatedly.

Subject: Results of survey "Do controlled vocabularies matter?"

Hello all,

we are happy to announce that the results of the survey titled
"Do controlled vocabularies matter?" are available now.

A short write-up and also the link to the report can be found here:

The report itself was published on issuu:

We would be happy to receive comments from the community on this.

As an interesting outcome it can be stated, that people working on controlled vocabularies
seem to have put aside scepticism about the semantic web finally.

On the other side the whole semantic web cake has not been digested yet:
E.g. only a few people from the vocab-community deal with Sparql, which brings me to the conclusion
that a "standard" layer encapsulating Sparql especially designed for SKOS based systems
might help in this situation.

Any activities going on in this area?

Best wishes,
