SPARQL Engine

The SPARQL engine included in TopBraid is essentially the ARQ engine from the Apache Jena API. It covers all SPARQL standard features plus a few non-standard extensions.

Note

Apache Jena is tracking the work on RDF-star and SPARQL-star, which means that some of the features that may be available go beyond the SPARQL 1.1 standard. Note however that these features are not supported by TopBraid and the SPARQL Query Panel or the SPARQL Endpoint Page may not allow entering such queries.

One of the most significant extensions to the standard SPARQL engine that is specific to TopBraid is the rich SPARQL Functions Library and the ability to declare new functions using the DASH vocabulary.
