2. What are the "objects" of the Pleiades Project?

We're using the architecture of the web for Pleiades. It's designed in terms of resources and representations. There are 2 categories of resources: ancient world resources, and research resources.

Ancient world resources are: Places, Locations, Names. These are descriptions of historical entities. A Place resource, such as Vani, is about an ancient place. Locations and Names always have a Place as context. All ancient world resources are governed by revision control and editorial policies and they will have a listing of supporting references. These resources comprise what people usually agree to call a "dataset".

Research resources are not part of the dataset. There are some site-wide shared resources like time period and feature type vocabularies, and collections (saved queries) of ancient world resources. Users may also create custom collections for their own research.

Underneath all of this are thousands of Python objects in several large B-trees, but that's an implementation detail. The reality of Pleiades is web resources.
