We have overall four alternatives, it seems:

1.  (ab)using the rif: namespace, i.e. rif:imports: might be acceptable, we need to check with rif group. 
    
    concern: may be confusing, since recursive imports are not considered as RIF-RF combination semantics doesn't know about rif:imports 

2.  (ab)using the rdf: namespace, i.e. rdf:rif-imports. 

    potentially similar issues as 1?

3.  use the sparql: namespace, which we need for functions etc. anyways... i.e.  sparql:rifImports or sparql:rif-imports
     pro: straightforward
     con: it was raised earlier that this import mechanism may be useful/needed by others, so we shouldn't tie it to sparql.

4. use a new namespace *and* a new prefix, eg. rif2rdf:imports where 
     @prefix rif2rdf = <http://www.w3.org/ns/rif2rdf#imports>



<chair-hat off> My personal opinion:

  While I am still worried a lot about the objection for 1. and fear objections against 2., I am starting to think about the objection against 3. with a bit more distance... why should we speculate about later reuse that is not yet there? In case, others are free to reuse sparql:rifImports. 

 - sceptical about 1.
 - neutral about 2.
 - in favor of 3.
 - neutral about 4. (admittedly, I have no idea for a "sexy" prefix name, not entirely happy with rif2rdf: )

</chair-hat off>

Other expressions of preference?
