This query requires data and vocabulary, together stored within the same dataset (but possibly in different graphs).

Created 5 months ago, 2 versions

Purpose

When a dataset uses Data Cube, it contains one or more Data Structure Definitions. This query visualizes such statistical schemas.

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.
