Fuseki comes with a few example config files that you can try out. One of them demonstrates how to set up the endpoint to work with a reasoner and specific RDF vocabuleries. Look for a file like this when you download it:

 

https://github.com/apache/jena/blob/master/jena-fuseki/config-inf-tdb.ttl

 

The documentation is here:

There are a lot of bells and whistles, but by taking it a step at a time it should be possible to hack the config to work with other vocabularies and instance data.

Thanks, Jeff. I'll get that running. Does the service run simply over test data, or does it make use of the vocabularies in the PREFIXs for defined domains and ranges? As I recall, SPARQL doesn't do any inferencing, but will it pay attention to domains and ranges inherent in the ontology? (I've mainly used SPARQL with data that has been acted on with a reasoner.)

If my question doesn't make sense, I'll just test it out when I get some data created, and have gone back over the SPARQL documentation.

Karen,

 

If you put your Turtle data onto the Web at a URL (e.g. using DropBox), you could use this general-purpose SPARQL service to experiment on it and create sharable links to live queries.

 

http://sparql.org/sparql.html

 

Put the URL for your dropbox data file into the “Target graph URI” field and enter your query in the text area at the top.

 

If you’re doing CONSTRUCT queries, you can get back Turtle by selecting Output: Text from the dropdown. For example:

 

http://sparql.org/sparql?query=DESCRIBE+%3Chttp%3A%2F%2Fwww.wikidata.org%2Fentity%2FQ8016%3E&default-graph-uri=http%3A%2F%2Fwww.wikidata.org%2Fentity%2FQ8016&output=text&stylesheet=%2Fxml-to-html.xsl

 

The service isn’t always available, like now L, but it’s handy when it is.

 

I keep one of these running on my Workstation so it’s always available. The installation instructions are pretty easy:

If the graph union includes the ontology, and the sparql query includes  "?S ?P :Work" , you will get bf:workTitle rdfs:domain :Work  .


I was speaking of the case in which bf:workTitle rdfs:domain bf:Title.


I always need to work these things out looking at actual triples, and thanks to insomnia, this is what I came up with last night:

<X> rdf:type bf:Work .
<X> bf:workTitle _:aa .
_:aa rdf:type bf:Title .
_:aa bf:titleValue "Here's my title" .

So SPARQL query something like:

SELECT ?s ?p ?o
Where {
   ?s a bf:Work }

Would you not get:

<X> rdf:type bf:Work .
<X> bf:workTitle _:aa .

If the bf:workTitle were of type bf:Work instead of bf:Title, you would get:

<X> rdf:type bf:Work .
<X> bf:workTitle _:aa .
_:aa rdf:type bf:Work .
_:aa bf:titleValue "Here's my title" .
  
Does that clear it up?

And I wish to gawd that there was some easier to use software that you could throw these kinds of tests to. I might be able to create a file to test it out in Protege but it's a big pain. However, having such a test environment would make it easy to try things out and see the consequences.
