Hi Andy and all,
thank you very much for the clear answer. We did not figure out that
the aggregation functions are arguments to the group operator. As you
pointed out, it was there under our eyes, but we were not seeing it
:-)

It's a pity that ARQ does not have a registry of aggregates. I
understand your proposal to tweak the parser process and to add an
AggregationRegistry. Still, this will require us to brach ARQ, isn't
it?
Yes.
Do you want new keywords for new aggregates or the possibility of
URI-function syntax for aggregates? or both?
We are happy to contribute to the ARQ code new aggregates,
Great!
but we
probably need some help in designing and implementing the
AggregationRegistry, can you help?
(in Fuseki)
org.apache.jena.fuseki.migrate.Registry<T>
which should really roll back to FunctionRegistry ,
PropertyFunctionRegistry but it's hardly a priority as the latter work
albeit predating Registry<T>.
Andy
Cheers,

Which aggregates do you want to add BTW?
