RDF vCard effort related to RDF iCalendar

Everyone,

There's been a discussion on the semantic-web list regarding RDF vCard, 
and I've been asked to share some of the discussion with this group 
because my current RDF vCard proposals relate to RDF iCalendar.

As a bit of a background, I'm attaching two documents. The first is an 
article I was writing, before I became aware of the semantic-web RDF 
vCard effort, addressing why an RDF vCard format is needed and 
advocating an approach to combining directory, vCard, and iCalendar.

The second document is a process document we've been discussing on the 
list. It systematically takes [RFC 2425] (Directory), [RFC 2426] 
(vCard), and [RFC 2445] (iCalendar) in an effort to create a consistent 
set of RDF ontologies from them.

I realize that there has been substantial work on RDF iCalendar. It's 
important at least to me personally that there is no duplication or 
inconsistencies in RDF vCard/iCalendar work. I welcome your comments, 
and feel free to join future semantic-web and/or online meetings 
regarding our effort.
