RDS/WIP sample queries in SPARQL

Contents

   2. 2. Get me all subclasses of PUMP, in a typical OWL format

Using the OWL/RDF native endpoint

The triplestores that hold the OWL/RDF content of the RDS/WIP have protocol endpoints conforming to the SPARQL Protocol Recommendation from the W3C. To query it using SPARQL clients, just enter the service URI of the endpoint you're interested in, for example: http://rdl.rdlfacade.org/data is the URI of the endpoint containing classifications outside of the base part 2 data model.

(@todo consider use of word base here versus core)

Using the PCA RDL endpoint

To execute the following scripts, go to the PCA RDL SPARQL query page.

These scripts are currently demonstrated against the PCA RDL endpoint, which represents ISO 15926 definitions in a form closely related to the evolving RDS/WIP form - they give some idea of the possibilities when using SPARQL with ISO 15926.

1. Get me all the subclasses of PUMP, in a table

If you wish to see what this returns right away, just click here to submit the query to the RDS/WIP.

2. Get me all subclasses of PUMP, in a typical OWL format

The following query serves to extract a (tiny) subset of the Reference Data Library, returning RDF data with rdfs:label applied for the names of the reference entitites. To see the output right away, click here. If you save the resulting page from your browser to a file, say pumps.owl, you can load it in an OWL application, such as the on-line OwlSight or the Protégé editor.
