The OSLC Query 2.0 specification does not explicitly describe whether an "=" operator on a string literal should be case-sensitive or case-insensitive. In most cases, a case-insenstive query is more accommodating to finding resources, especially since the spec does not support string pattern matching - see https://issues.oasis-open.org/browse/OSLCCORE-157.

However, the spec references https://www.w3.org/TR/rdf-sparql-query and in that, string equals is case sensitive. This is perhaps one case where strict adherence to SPARQL for our abstract OSLC query makes it less usable to users.
