If you use dc:title / dc:description or rdfs:label / rdfs:comment, your data may not be included in Google Rich Snippets. I really don't understand such a design decision by Google.

Also, for E-Commerce applications, it may make sense to have a specific GoodRelations property for textual elements. Yes, I guess, it will still take some time that traditional search engine developers will hopefully grasp the advantages of multiple namespaces. This is one reason that makes the difference between database schemata (or similar approaches where everything is redefined everytime) and a kind of "shared understanding" which can be created by the usage of common (terms of) ontologies, such as DCTerms. We should force the application for multiple namespaces (vocabularies), instead of avoiding it. Cheers, Bob
