Perhaps I've missed some of what has already been published.  Is there stuff beyond these two pages?

The only request for input that I saw was for help with property mapping:

   https://lists.wikimedia.org/pipermail/wikidata/2015-June/006503.html

which I and several others commented on, but questions like "Has this been reviewed by anyone at Google familiar with the Freebase schema?" were ignored and comments like "Don't select properties based solely on frequency" and "Ignore deprecated properties" were rejected.

My closing comment was that there was a bunch of really basic groundwork to be done before it made sense to ask for wider review, but, as far as I know, that was the last thread addressing the project.  When I look at the mapping page is still see a ton of duplicate entries, deprecated properties, user & base properties which don't make sense to import and other cruft that people shouldn't have to wade through.

If there have been frequent requests for input, they've been in fora that I don't follow.
