1. I thought that it was a requirement that the query language would support the full expressivity of RDF graphs. After all, it doesn't do much good to have assertions in a graph that one cannot query. IMO, a query language that does not support arbitrary typed literals is not an RDF query language. 2. Simply adopt the standard N-Triples notation for typed literals including support for qnames (e.g. "10"^^xsd:integer). If a given query engine/service supports the datatype in question, fine, else it issues an error. But I've covered this in detail in earlier postings to the DAWG list. Do a search. I'm sure they are easy enough to find in the archives.
