For the second question, while I agree that ontologies and reasoning stores are ultimately the right answer to this problem, in the short-term and small-scale, equivalent (modulo context) predicates can be handled in SPARQL using UNION or, if one predicate is preferred, using multiple OPTIONALs. I wrote about this second technique just the other day: http://www.thefigtrees.net/lee/blog/2006/04/sparql_calendar_demo_using_spa.html Lee Definitely good questions, and good answers as well.
