Where is bif: URI?

Solution to my problem requires to use bif:st_intersects. I wanted to see the bif ontology i.e. to see what is it, and what is exactly st_intersect, but on dbpedia list of namespaces, bif: does not redirect to any web resource. Why?

Solution

  • bif:st_intersects is a custom Virtuoso predicate. It works only in Virtuoso, just as spatial:intersectBox works only in Jena. Its definition is rather operational than ontological.

    Additional examples of usage: 1, 2; from 2:
