Hi Andy, Shane McCarron spotted this bug in the SPARQL.org implementation while running his RDFa processor against the RDFa test suite[1]. When we have a triple like this: <http://example.org/library#book> <http://purl.org/dc/elements/1.1/identifier> <urn:isbn:0752820907> . ... running a SPARQL query on the graph above, like this: ASK WHERE { <http://example.org/library#book> <http://purl.org/dc/elements/1.1/identifier> <urn:ISBN:0752820907> . } ... will return a negative result. Note that the triple has the "isbn" value in lower-case, and the SPARQL query has the "ISBN" value in upper-case. Per RFC2141, section 6[2], the following URNs should be lexically equivalent: urn:isbn:0752820907 urn:ISBN:0752820907 urn:iSbN:0752820907 This seems to be a bug in the SPARQL engine - can you please verify that it is, or let us know why it isn't? Thanks in advance :) -- manu http://rdfa.digitalbazaar.com/rdfa-test-harness/ http://tools.ietf.org/html/rfc2141#section-6 -- Manu Sporny President/CEO - Digital Bazaar, Inc. blog: Bitmunk 3.0 Website Launches http://blog.digitalbazaar.com/2008/07/03/bitmunk-3-website-launches
