@bonfire A bit, yeah. I'm sure each one has pros and cons for the purpose, but I'm in favor of picking something that's ready for use with linked data. We might be able to avoid defining a new JSON-LD context that way.
schema.org's CreativeWork is a supertype of ScholarlyArticle. Curious why ORCID doesn't use the subtypes even though they have the type information in their own data. (Their JSON schema is altogether different from their JSON-LD I think.)
