Suggest creating a category structure
As I said in an email response this morning, having OER authors complete the OER_Metadata template will go a long way to providing data about developing resources. And as you suggest, we can work in the background to figure out how best to use that data to maximize finding (and thereby reusing) resources. Categories seem to be the current solution to this, but Jim has some good suggestions in his email response below and we need to consider how the subpage structure will play out (agreed, there could potentially be an enormous number of resources for beginning fractions, grade 3 and otherwise, even within one country -- organization of it all will be challenging and ongoing).
As for how to achieve an alphabetical listing of many subpages on a category page, I don't have any ideas, although I have noticed that Wikipedia does something to create an alphabetical listing that ignores the namespace (but I'm guessing you all know about that already:)
To get us started thinking and give us a place for discussion about whether and how to implement categories, Jesse has started Workgroup:Categories. I'll sign on, so with one more volunteer we can initiate a community workgroup and get to work.
