1.5.62. How to Use SPARQL to add missing isDefinedBy relations to an Ontology?
¶
Why?
isDefinedBy relations make Ontologies (TBox) more navigable using follow-your-nose pattern. This also makes ABox instance data more discoverable.
¶
How?
Use SPARQL to generate relations that associate Classes and Properties the Ontology that describes them.
¶
Example Using the Ontology for vCards
In this example we will use:
-
Ontology Document URL: http://www.w3.org/2006/vcard/ns ;
-
Ontology URI: http://www.w3.org/2006/vcard/ns# ;
-
A local Named Graph IRI to host SPARQL Update (SPARUL) the new relations.
## Uncomment line below if using Virtuoso and executing SPARQL via iSQL
## or via an ODBC, JDBC, ADO.NET connection
## SPARQL
## Uncomment line (a SPARQL pragma) below if using Virtuoso and there
## isn't a local Named Graph holding triples retrieved from the Ontology URL
## DEFINE get:soft "add"
INSERT INTO <urn:data:qos:vcard>
{ ?s rdfs:isDefinedBy <http://www.w3.org/2006/vcard/ns#> }
FROM <http://www.w3.org/2006/vcard/ns>
WHERE
{
?s a ?o
}

Example Using the Recorded Media Ontology
In this example we will use:
-
Ontology Document URL: http://www.w3.org/ns/ma-ont ;
-
Ontology URI: http://www.w3.org/ns/ma-ont# ;
-
A local Named Graph IRI to host SPARQL Update (SPARUL) the new relations.
SPARQL
INSERT INTO <urn:data:qos:ma-ont>
{ ?s rdfs:isDefinedBy <http://www.w3.org/ns/ma-ont#> }
FROM <http://www.w3.org/ns/ma-ont>
WHERE
{
?s a ?o
}
