[protege-discussion] SPARQL querying in Protege

[Mariana Damova]

HI thank you for this answer.

 

Actually, my question was more specific, not about SPARQL, but about SPARQL
in Protégé.

How do I specify a prefix for an entry that says: 

rdf:ID=”PizaToping”

 

where rdf: refers to the standard namespace for rdf

 

This is an example form Protégé’s exempalry ontologies.

 

I would like to query the countries with SPARQL, using Protégé, but I
cannot.

 

Best,

 

Mariana

I would recommend you to look at one of these tutorials:
http://jena.sourceforge.net/ARQ/Tutorial/
http://www.cambridgesemantics.com/2008/09/sparql-by-example (move forward
with space or right arrow)

Even the Wikipedia page about SPARQL could be a good starting point:

Hi:

 

Can you give me an example of how do I specify Prefixes from rdf:ID=”
xxxx”,

So that I can formulate an executable SPARQL query in Protégé.

 

My question is overall, how do I get ot an executable SPARQL query using
predicates other than rdf:subClassOf and Classes from a given ontology.

 

Thanks.

 

Best regards,
