By request, I updated the links for VoID (on the vocabulary page and elswhere on the wiki to

I'm thus envisioning two library audiences: as novices who want an overview and experts who want a quick lookup/refresher.

>> 
>> I see that the overall grouping is currently based on "metadata element sets" versus "value vocabularies and datasets". I know we had extensive discussion on that distinction but must admit that I'm still less-than-clear on it! Good news is it looks like our definition [7] is planned to be included [8] someplace in the prelude to this section!

Beyond places and persons (which are well-covered in your draft) there are events (maybe in CIDOC CRM? If so, more details on that could help!), measurements,  colors,  etc.
