Two of them. The first is the current state of the work by the W3C in 
creating a sequel to Renato's original W3C RDF vCard note:


The second is the attached document, which I wrote as an independent 
procedure for creating a comprehensive RDF vCard specification that also 
encompassed iCalendar and general text/directory information. It was my 
aim to start from scratch and see where it went, and then try to resolve 
the result with the W3C work.

The discussion has been largely contained to this group, with 
notification to www-rdf-calendar. The current major issues include:

* For many properties vCard (and text/directory in general) can take a 
single value or multiple ordered values; how do we represent this in RDF 
in a simple way without losing semantics?

* vCard can provide attributes, such as *home* phone and *preferred* 
email, which are not properties of the value but of the relationship; 
how best to represent this in RDF?

* How can we synchronize with the RDF iCalendar work for properties in
