GRDDL
This page is new - please help to populate it!
Introduction
GRDDL (pronounced "griddle") is a mechanism for Gleaning Resource Descriptions from Dialects of Languages. It is a technique for obtaining RDF data from XML documents and in particular XHTML pages. GRDDL transformations can be made for almost any dialect, including microformats.
Implementations
- W3C GRDDL Service
- Triplr - construct URL as http://triplr.org/rdf/example.com/page.htm
Profiles
Transformations
- hCalendar
- http://www.w3.org/2002/12/cal/glean-hcal.xsl
- hCard
- http://www.w3.org/2006/vcard/hcard2rdf.xsl
- http://norman.walsh.name/2005/12/12/examples/hcard2rdf.xsl
- vote-links
- http://rdf.opiumfield.com/vote/votelinks.xsl
Issues
- Is GRDDL in HTML 4.01 OK, or is it just for XHTML?
- Surely parsers can convert valid HTML4.01 to XHTML, perhaps using HTML-Tidy, before parsing it?
- The specification states that it is intended for XML and XHTML, but 'profile' is in the HTML4 specification. Parsers can implement Tidy or other conversion routines, but do not have to. --TomMorris 03:49, 13 Oct 2007 (PDT)
- Restricting GRDDL to XHTML would seem to be unnecessarily limiting. Andy Mabbett 04:00, 13 Oct 2007 (PDT)
- The specification states that it is intended for XML and XHTML, but 'profile' is in the HTML4 specification. Parsers can implement Tidy or other conversion routines, but do not have to. --TomMorris 03:49, 13 Oct 2007 (PDT)
