Re: [dotNetRDF-Support] RULEBASE support in Sparql Parser

[Rob V. <rv...@do...>]

Your query appears to use several non-standard SPARQL features that I have
never encountered before.  Setting the syntax to Extended only enables
syntax extensions we have implemented not arbitrary extensions.

RULEBASE is not a standard feature and a quick Google search didn't tell me
where it comes from?

Also what is the following supposed to be?

<ReadTagList>( ?oref1,  ?oref1ts,  ?o1,  ?o1Status)

It looks like some sort of extended syntax (again I don't know where from)
which would also be rejected?

What tools/product do your SPARQL queries originate from?

We implement SPARQL 1.0 and SPARQL 1.1 per the standards (and are 100%
compliant with those), the extras in the extended syntax are primarily
leftovers from the transitional period when the features of SPARQL 1.1 were
still under development and will most likely be removed in the long term.
