Thanks for asking this question! This is a topic I’m really interested in, too. We’re constantly looking for ways to facilitate listing/sharing resources among our partners, but we haven’t yet found a tool that everyone is comfortable weaving into their workflow.
A few of your bulleted needs made me think of Kumu. I haven’t yet used it myself, but was just at a conference where they used it as a way of presenting the connections and shared principles between a bunch of different assessment frameworks. https://kumu.io/
If you find a solution, I hope you’ll update this thread, I’d love to hear more and learn what I can!
