The documents are relevant to Race to the Top, and the Statewide Longitudinal Data Systems, supporting components of the standards. There was no attempt to present them as standards content.

I would agree with Dude that the core standards web site itself (i.e., the links he provided) is a good place to start if you want to learn about the standards.
Yes, that is a great starting point for learning about the standards. Interested parties may wish to read further and explore the websites which common core links to, and also learn about the supporting components, as described by the US Department of Education (linked upthread).

Web pages are easily updateable; dated documents possibly less so. Each may serve a purpose toward "gaining the maximum insight or knowledge possible from each source".
