Schema usage and licensing


Could somebody clarify exactly how the licensing agreement described at is supposed to apply to websites making use of this standard?

The terms of service note that, [the rights are],
"...licensed to third parties under the Creative Commons
Attribution-ShareAlike License (version 3.0)".

I assume that the intent is to allow unrestricted usage of valid schema
markup, but protect the published standard.

However, my understanding is that a strict interpretation of this
licensing requirement would:

1. Require any website making use of the schema vocabulary to include an
attribution to

2. Cause the content of any website making use of the published schema
vocabulary to fall under the same license.

So far, despite much interest in including such semantic markup in all
of my projects, I've completely avoided the standard described at for these reasons.

Is this an open, un-encumbered standard or should I develop my own?
