On a related note, I've experienced and observed some confusion about the scope of property definitions as defined in the English spec. It's clear from looking at the OWL source [1] that all of the existing schema.org types that include, e.g., "duration", are really all talking about a common property "http://schema.org/duration". But that's not as clear from the web site text. I think there's an implied promise that all schema.org properties are in a single global schema.org namespace now and in the future, and that any schema.org extensions will honor that [2]. Being able to rely on this would help me simplify certain schema.org specific code a bit. Based on this thread and other discussions I'm going to go ahead and assume this property. It would be good to document it officially too. John Panzer [1] http://schema.org/docs/schemaorg.owl [2] Of course non-schema.org microdata entities can exist and won't follow these rules; I'm just trying to document what comprises a well defined schema.org extension.
