The shared block library behind NWIOI's course tooling. A document is an ordered list of blocks; every block kind is a plugin, so discussions, assignments and labs sit alongside slides and quizzes as first-class content.
Grace is a component, not a product you log into. Documents are provisioned by NWIOI Instruct when an instructor is invited to build a class, and delivered to students through the NWIOI LMS, where enrollment decides who can see what. If you're an instructor, your editing link arrives by email.
Faculty with an NWIOI account sign in for the editor and the class view (rosters, discussions and submissions, read-only). Creating a document still happens only through Instruct's provisioning, deliberately.
What every consuming app reads instead of keeping its own copy — /api/registry.
