Dear GRDDL WG members,

Reading the GRDDL spec it is not clear to me what will be the alternative mechanism to be used when a XSLT sheet is not used for extracting RDF from a document. It seems to me that the only option is to create a "dummy" XSLT that invokes a URL that actually retrieves or generates the RDF.

I think that it could be very useful to have a new attribute with "retrieval" semantics and not wih "transformation" semantics. As a result, GRDDL will be the standard mechanism in the web used for locating the RDF associated to a web page.

Proposed syntax:

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:grddl='http://www.w3.org/2003/g/data-view#'
      grddl:retrieval="http://www.example.org/jsp/myrdf.jsp"
 >

or using the profile-based syntax
<html xmlns="http://www.w3.org/1999/xhtml">
  <head profile="http://www.w3.org/2003/g/data-view">
    <title>Some Document</title>

    <link rel="retrieval"
       href="http://www.example.org/jsp/myrdf.jsp" />

I look forward to your comments on this

Best wishes
