Dan, Thanks for your answers - better late than never ;) regarding 1) Source: Textual/non-XML vs. XML vs. Other: I agree: it is out of scope for now, but it could lead to a Liaison between GRDDL and MMSEM-XG on that topic in future regarding 2) Exploiting existing Web Sources: My idea was simply to define a "decoration" for well known HTML-sources (structures) as e.g. the Google result page format and offer a GRDDL-transformation for creating RDF triples. Might be to fancy, indeed :) regarding 3) Sounds good to me. Otherwise it is hard convincing people to go for RDF. Again, thanks for your answers - I'll continue to follow your work, try to contribute by simply using RDFa/GRDDL in my realm and continue to comment on the GRDDL WG drafts ...
