Creating a custom ontology

Most of the ontologies are written in the trig syntax.

In order to install an ontology, the follow files are required -

• ontology-name.trig The TriG file containing the ontology
• ontology-name.ontology.in A file describing the ontology

In order to ease the process of creating custom ontologies a template ontology is provided in kdeexamples/nepomuk/ontology
