> Support dynamic function invocation in ARQ
> ------------------------------------------
>
> Key: JENA-270
> URL: https://issues.apache.org/jira/browse/JENA-270
> Project: Apache Jena
> Issue Type: New Feature
> Components: ARQ
> Affects Versions: ARQ 2.9.2
> Reporter: Rob Vesse
> Assignee: Rob Vesse
> Labels: call, dynamic, functions, sparql
>
> Per my suggestion to the SPARQL Working Group I am proposing a new built in
> CALL() which can be used in SPARQL queries for dynamic function invocation.
> CALL with no argument returns null
> CALL with some arguments evaluates the first argument, sees if the result is
> a URI (if not errors) and if so tries to generate a function from it and
> invoke it with the arguments to that invocation being the remaining arguments
> to CALL
> I have implemented a prototype implementation of this in the ARQ language
> which I have committed to Trunk, others with more knowledge of expression and
> function evaluation in ARQ may have suggestions on how to improve the
> implementation
