---------- Forwarded message ---------- From: Axel Polleres <axel.polleres@deri.org> Date: Fri, Oct 24, 2008 at 10:42 AM Subject: comments on rdf:text solicited To: "Public-Rif-Wg (E-mail)" <public-rif-wg@w3.org>, public-rdf-text@w3.org 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.
