Some of those lists (e.g. of religious groups, movements; present day and historical) might be useful components that could theoretically be shared by intellectual subject classification systems. For answering a 'what kind of building is this?' question, it seems natural to aspire to 'plugging in' Wikipedia/Wikidata and other sources, so http://en.wikipedia.org/wiki/Temple_(Latter_Day_Saints) used as a type could provide a more detailed sub-type of PlaceOfWorship. And it seems more appropriate for those giant (often subtle, sometimes controversial) lists to be maintained at Wikipedia and elsewhere, hence blog.schema.org/2012/05/schemaorg-markup-for-external-lists.html Meanwhile someone might be cataloguing a phd thesis, youtube video or ScholarlyArticle on - say - traditions of Feminist thought in the Mormon community. It seems that we would want some commonality, ... that the relevant identifiers for the religion should be linked somehow. But that it is also useful to have the 'about' property reserved for the intellectual-content-oriented uses associated with CreativeWork. Dan
