[goodrelations] vcard:tel used incorrectly in the Quickstart Guide

Hi Vasiliy:

You are right, the use of tel as a plain datatype property is in partial 
violation of the latest 2010 vcard ontology spec. However, we currently 
recommend to stick with the Yahoo vcard representation pattern, since 
that is necessary for augmented rendering of phone numbers in Yahoo.



I hope this explains our current recommendation.
Best wishes


PS: IMO, SPARQL queries must tolerate a bit of deviation from standards. 
For example, there are at least three ways of using geo position data in 
Web pages:
