Settings > Namespaces and Prefixes

This feature from the Settings Tab can be used to view and edit the namespace prefixes for the current asset collection.

Note

Namespace prefixes are used to abbreviate the full IDs/URIs of assets. For example if the full URI of an asset is http://schema.org/Person and the namespace prefix for http://schema.org/ is schema then the full URI can be abbreviated as schema:Person. These shortened names are often called qnames.

In TopBraid, namespace prefixes are used in the Turtle export format (which is also used by the Source Code Panel), in SPARQL (for example the SPARQL Query Panel) and on all panels where the user has activated the setting to prefer qnames over display labels.

Namespace prefixes are also used in some code generation algorithms such as GraphQL schemas and the generated ADS APIs.

Caution

There should only be one prefix for each namespace. Unfortunately even some well-known namespaces are used inconsistently across the RDF world, for example dct and dcterms. Avoid this at all costs, and establish concise namespace practices for your projects.
