<AndyS> from this discussion https://github.com/w3c/data-shapes/discussions/637#discussioncomment-14893773

AndyS: priority on 840

AndyS: Creating new terms is mandatory; we need to solve it and it will not be marked at risk

ajnelson-nist: discussion on imports; cannot import a shacl shapes graph multiple times, because of blank nodes
… was this addressed previously and, if not, where should we address it?

AndyS: load via URL only once
… but edge cases might still load multiple times

ajnelson-nist: each graph has 2 names/URIs to get them because of versionIRI

AndyS: no perfect answer; you just have to be careful

mgberg: draft pull request -> owl imports checks versionIRI
