Re: [dotNetRDF-Support] Unexpected query result

[Rob V. <rv...@do...>]

The query only matches a single triple which is why you only get one result

"two" is not the same term as "two"^^xsd:string

The recent RDF 1.1 specification says that "two" is implicitly typed  such
as to be equivalent to "two"^^xsd:string but this is not a specification
that we yet support
