List of Prefixes for SPARQL Queries - DDMAL/linkedmusic-datalake GitHub Wiki
The following is a list of prefixes that can be used in SPARQL queries without needing to be explicitly defined. Virtuoso also has a list of standard RDF prefixes that aren't included in this list but that also don't need to be explicitly defined.
One thing to keep in mind is that slashes (/
) cannot be used with prefixes, so things like diamm:archives/12
or diamm/archives:12
are invalid.
For TheSession, URIs for tunebooks are of the form https://thesession.org/members/{user_id}/sets/{set_id}
, thus making prefixes unusable for this entity type.
For instructions on how to add prefixes, see this section of the Virtuoso setup guide.
