Hi Linda,
Thank you getting in touch with the group.
One area that may be relevant here is how SPARQL addresses extensions
and has the ability to call out to non-RDF indexes, algorithms, and
services. While engines have ways to do this today, mostly by creative
use of the SPARQL syntax and sometimes syntax extensions, there is
interest in a common facility with defined execution semantics. Staying
within the syntax of the SPARQL spec has always been popular with many
users.
Issues in this area include:
#6 Function call - algorithms and indexes.
#64 Named arguments for SPARQL functions
#20 Dynamic function invocation
#46 SPARQL-friendly lists
Questions to the Spatial Data on the Web Interest Group:
1. Does the approach of a common way to access specialized facilities
work? Are there missing items of functionality?
2. What would the ideal way and syntax be to access geospatial
functionality?
