Context: when we did the Q/A design a few years ago (/cc @scor) we included a "QAPage" construct, to capture the idea that there are pages which carry collections of questions and answers. In retrospect I wasn't sure that it was a great idea, but the type is there.

Talking with colleagues at Google, we are interested to have schema that distinguishes "Frequently asked questions" content on the Web. Often these are several Q/A pairs to a page, sometimes organized into categories. Other times they are published one page per question.

We think "about" or "keywords" properties could handle the categorization aspect, and that perhaps the itemref construct might be useful to avoid duplication/verbosity when using Microdata and when all the items in one category have the same keywords. As an aside, perhaps in future "categories", "keywords" could be considered as subproperty of "about" and their structure/definition converged.

Proposal:

Add a new type FAQPage as a subtype [edit: or sibling] of QAPage, definition:

A [[FAQPage]] is a [[QAPage]] presenting one or more "Frequently asked questions".

We would add examples for a single page with a single question, and for a larger page with several questions, including categories handled via "about" and/or "keywords" properties on the QAPage and/or the Question (assuming that Answers rarely get dedicated metadata for such things).
