Multi-function

A multi-function is a function that can return zero or more result objects consisting of one or more result variables. While normal (SPARQL/SHACL) functions can only return a single result node, multi-functions may not only return multiple nodes but even multiple individual variables per solution. A common way of defining multi-functions is by wrapping a SPARQL SELECT query, using dash:SPARQLMultiFunction. However, some MultiFunctions (in TopBraid) may also be implemented natively.
