My opinion on your volunteering is that it's great! About events in drupal... my first instinct was to suggest hCalendar+GRDDL assuming that (a) the drupal folks had good hCalendar support, and (b) the linked-data/RDF experts could handle the other details with GRDDL. But did some searching to confirm (a) and was surprised to find only scraps... 2007 forum postings and such. And I'm not sure to what extent linked data consumers support GRDDL... though I think many of them support hCalendar directly. I hear there's recent work on RDFa in drupal, but I don't know much about it. Maybe that would be the way to go. About the style of the vCard submission, it looks pretty good, but I'd be happier if it had a test suite showing conversions to/from vCard syntax. There *is* a test suite for iCal/rdf-calendar: http://www.w3.org/2002/12/cal/report1173.html#testdr And I developed a converter for hCalendar->rdf-calendar; I can't remember how far I got in checking it against the hCalendar test suite. See section 15.1. hCalendar and microformats for some details. http://www.w3.org/2002/12/cal/report1173.html#L1879 The conjecture to check would be: fromIcal(x2v(foo.html)) rdf-graph-equivalent glean-hcal(foo.html) for each foo.html in the hCalendar test suite. > > Cheers, > Michael > > [1] http://twitter.com/cardcc/status/9149850904 > [2] http://twitter.com/cardcc/status/9148914765 > [3] http://lists.w3.org/Archives/Public/www-rdf-calendar/2008Dec/0000.html > [4] http://lists.w3.org/Archives/Public/www-rdf-calendar/2008Dec/0013.html > [5] http://www.w3.org/Submission/2010/SUBM-vcard-rdf-20100120/ > -- Dan Connolly, W3C http://www.w3.org/People/Connolly/ gpg D3C2 887B 0F92 6005 C541 0875 0F91 96DE 6E52 C29E
