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 :)
