Have a talk to your w3c staff contact. It is usually possible to fix obvious things like this. Particularly if the namespace was already allocated, so the URI set is already implied. ________________________________ From: Martynas Jusevičius <martynas@atomgraph.com> Sent: Saturday, 2 December 2017 12:05:24 AM To: Gregory Williams Cc: Andreas Harth; Sean B.

I have a use case for it :) To specify the function to apply in a FILTER. I'd much rather use a function URI than a label literal.

During the SPARQL 1.1 WG, it was always my intention to define IRIs for all the built-in functions. We even set up a namespace for it[1]. Alas, it seems it was never properly populated, as BOUND is the only function with an assigned IRI. Maybe it would still be possible to get those all assigned-I still have local working copies of what I think should be in /ns/sparql. Thanks, Greg [1] https://www.w3.org/ns/sparql
