[sc34wg3] TMQL: XML content vs. < > delimited IRIs

[Lars Heuer]

Hi Robert,

> For TMQL I have now:

>   "http://whatever/"    # interpreted as IRI literal

How does the parser know that "http://whatever.com/" is not meant as
string?

>   "http://whatever/" ~  # IRI literal used as subject identifier

>   http://whatever/      # stand-alone IRI used as subject identifier

The "" around IRIs is necessary, if someone wants to refer to a topic
by its subject locator / subject identifier and wants to use the axes?

The:
   http://whatever/ ~
and
   http://whatever/ =

would be an error then?


> Is this along your thinking?

<> for rootless IRIs and http://... for subject identifiers is aligned
with CTM. But "http://www.example.org/" is not supported by CTM, it
would be interpreted as string, unless the datatype is made explicit:

      "http://www.example.org/"^^xsd:anyURI

works.

Best regards,
Lars
