Dear all,

find at
 http://www.w3.org/2007/OWL/wiki/InternationalizedStringSpec

the prefinal version of the rdf:text datatype, now with
Xquery/Xpath-style built-in functions added.

I have added a rudimentary set of built-ins.
The most essential ones are those from seciton 4.1. to assemble and
disassemble rdf:text.

The others (sections 4.2, 4.3) are mostly syntactic sugar, which is
shown by for most of them also a declared XQuery function being given
to emulate them. Still, I think these are important enough to be kept
in the spec.

An exception is  fn:matches-language-range which exposes language
range matching as defined in RFC 4647 (part of BCP-47) as a built-in
function.

I think thee cover the most essential functions needed for rdf:text.

The RIF versions of these will be defined in an update of DTB, along
with examples how to emulate (min-/max-length, etc.) facets using
these functions in RIF rules.

Please comment until mid next week latest, since the OWL group really
needs this document to be finished.

Axel
