@jgmac1106 Perhaps we might create and use a corner of the IndieWeb wiki to begin documenting the use of these types of things? We could start on the https://indieweb.org/Indieweb_for_Education page and subsection them out as they grow in size and scope? If there are consuming applications for differing types of metadata, let's list those. The best answer may be to begin documenting pieces of what are out there and then figuring out a way to create more IndieWeb or decentralized and open versions of them. Having an editable, but centralized source of information can certainly be helpful. (Unless you know of another that already exists?)
