Since the vCard ontology is really a derivative of the vCard  
standard, then it would seem eccentric to start unilaterally  
deprecating bits of it.  It might also probably be counterproductive,  
as Kjetil said.

It would also thwart a simple-minded (ie, immediately  
intelligible) .vcf -> .rdf translation.  If all the tags in the vCard  
spec are present, undeprecated, in the target ontology (including  
declared relations to other ontologies), then such a translator might  
not be that much more elaborate than a sed script.  Which would be  
nice.  If someone writing such a utility has to grok the  
documentation for a bevy of other ontologies, it's suddenly a more  
elaborate, and errorprone, project.

It's not as if either the vCard or other ontologies is likely to  
change _so_ rapidly that this becomes a maintainance burden, is it?

Also, re

>   http://www.w3.org/2006/vcard/ns#longitude

these are not "the same as" the geo: ontology, but are instead more  
generic (correctly: c.f. the other thread).

See you,
