GoodRelations is a standardized vocabulary for product, price, and company data that can (1) be embedded into existing static and dynamic Web pages and that (2) can be processed by other computers. This increases the visibility of your products and services in the latest generation of search engines, recommender systems, and other novel applications.

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. See http://developer.search.yahoo.com/help/objects/local I hope this explains our current recommendation. Best wishes Martin 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: http://www.ebusiness-unibw.org/wiki/GoodRelations_and_Geo_/_Location_Data On 13.06.10 21:42, Vasiliy Faronov wrote: > Hi, > > In the GoodRelations Quickstart Guide, for example in [1], the vcard:tel > property is used incorrectly, like this: > > :x vcard:tel "+1 234 56 78 90" . > > i. e. it points directly to the telephone number string.
