Your speculation about a consortia sharing one Work resource gets to the heart of whether BIBFRAME is Linked Data or whether it's just records being represented in RDF. Have you considered if and how BIBFRAME should use owl:sameAs to bind resources together? If it's allowed, should the URIs be interpreted as the same Work (regardless of how or where it is described), or the same BIBFRAME data published in various places?

Naturally, it's too early to answer that question in regard to your spelling example, but I entertain thoughts wherein a lot more automation is employed to keep things up-to-date.  Could there not be a reference to the source of *your* Work's description that could be used to look upstream for changes?  Does BIBFRAME enable such a feature (if not, could it)?  What's needed to enable such as use case?

In a consortium setting, for example, might there only be one Work resource?   In such a scenario, individual libraries will generate Instance resources, as needed and to be shared throughout the consortium.  Then individual libraries would attach Holding resources to the Instances.
