Trial of SPARQL on GraphDB

I used the OWL ontology files from Allen Brain Atlas (ABA) Adult Mouse Brain Ontology

Then used SPARQL Query on GraphDB

http://localhost:7200/import#user

First you need to Import the file using Import → RDF → Server Files

Then use SPARQL Query & Update - http://localhost:7200/sparql

Sample SPARQL query that I used:

select distinct ?o where {
  ?s ?p ?o .
  filter contains(?o,"Cerebral cortex")         #-- the important line
}
limit 100

Result:

1	Cerebral cortex, layer 5
2	Cerebral cortex
3	Cerebral cortex, layer 2-3
4	Cerebral cortex, layer 6a
5	Cerebral cortex, layers 1-6b
6	Cerebral cortex, layer 1
7	Cerebral cortex, layer 6
8	Cerebral cortex, layer 3
9	Cerebral cortex, layer 2
10	Cerebral cortex, layer 4

Schema.org - has more RDF / triples: https://schema.org/docs/developers.html
