datatype-overview

Purpose

This query enumerates the datatype IRIs that are used in the dataset.

Implementation

This query uses the datatype/1 function to retrieve the datatype IRI from RDF terms. Since non-literal terms do not have a datatype IRI, ?datatype will sometimes remain unbound. This is why we need an additional filter containing the bound/1 function to rule out this result.
