It denotes a value in a specific value space. And the value is denoted by the pairing of lexical form to data type identity. E.g. _Robby weight <unit:kg:14> . The relation between the data type denoted by unit:kg and its interpretation as e.g. an integer or number in general is beyond the scope of RDF. > Yes, I do.
