"but it would be very helpful if people reading this could link to any
sites they know which have shareable competency frameworks from any
educational or training sectors"
The problem I currently see with letting someone have access to a Moodle site to see or share via upload or download of competency frameworks is that the viewer needs to have manager, or admin level access to the site. The view that a teacher has of competencies in a course is vastly different than the framework view and at that level, they have no way to upload or download.
I do have about ten samples I'm willing to share, if anyone wants to contact me via email at, drachels at drachels dot com. I have five that cover Alabama Technology Education from K thru 12, Alabama and Minnesota 3rd Grade Science, Minnesota 6th Grade Science, Common European Framework of Reference for Language, and a couple of other works in progress.
