Hello FOAFers!

Funny you should mention phone numbers.

We recently had to decide how to deal with home, work, mobile (cell) phone 
numbers in FOAF so we've added a foaf:type which I'm not sure able?

   <foaf:name>Jonathan Greensted</foaf:name>
   <foaf:phone foaf:type="mobile">tel:070 9211 9075</foaf:phone>
   <foaf:phone foaf:type="business">tel:014 8368 5555</foaf:phone>

What do you guys think?

Also, there's a standard set of properties to an Outlook contact record which 
we could also add.  Should we extend the FOAF namespace or create a Outlook or 
FreddieOutlook namespace?

If you would like to see the FOAF we generate please download the Outlook2FOAF 
beta via here:


All feedback is greatly appreciated.


PS. Freddie knows that the largest FOAF file today was created by Thomas Power 
using the Outlook2FOAF tool.  12k+ knows/Person things in a single file!
