 Aperture will move to the Nepomuk NIE [2] ontology soon, where we have
further formalized vCard [3], vCalendar, and many other things. We have made
some suggestions[4] on the calendar-dev mailinglist for needed bugfixes of
[1], but the list is hibernated, and then we decided to roll our own.
    

Leo -- what does this mean for the ongoing work here on an updated vcard-in-rdf?
  
I cannot say what implications this has for you, because I don't know your organization nor standardization body nor the work you are doing in detail.

perhaps you could give me more detail?
(note: I cannot follow the discussion on semantic-web@w3.org, too much traffic for me :-/

We created NIE as a standard for the Semantic Desktop, within the Nepomuk.semanticdesktop.org project, and we plan to implement it with a reference implementation (aperture.sf.net). Standardization is first by best practice and community, later we aim for official standardization bodies (ISO, W3C, OASIS, still an open question).

What may help us both is when you look at NIE [2] and especially the ontology [5] and if you find bugs, send them to us, if not, just use NIE as it is.
By this way, we can also both work on Aperture to get good data->rdf converters.

If you think that NIE is not what you had in mind, you can use anything else. Ontologies are an open market :-)
And what to do about the calendar work? It's unfortunate you got no
response from the W3C hosted list.
  
yes, but we have a 15mio€ EU project running and need to deliver something every few months, we couldn't wait for the calender group to fix it. I am pragmatic in this regard. We are happy that we have NIE working now.

Antoni Mylka was the main author of NIE, he used input and discussed with developers from Aperture, Beagle, freedesktop, strigi, etc.
