Re: Schema usage and licensing

Hi Tati - 

Concerning #2, in my opinion, one needs to distinguish between the subject matter (i.e., the Schema taxonomy itself) and the material to which it is applied (your website).  The CC license relates to the “the Work,” which is defined as:

"Work" means the copyrightable work of authorship offered under the terms of this License.

So, you don’t bring your website into the orbit of the Work ( simply by virtue of using it.  If you were to publish your own extensions that incorporate or derive from Schema, it might fall under this license.

Your item #1 is potentially more troubling.  The CC site summarizes this requirement:

If supplied, you must provide the name of the creator and attribution 
parties, a copyright notice, a license notice, a disclaimer notice, and a
 link to the material.

Is this “supplied” at  Interesting that “” and its uses are self-referential URIs.
