What is the adequate terminology for describing a page/view representing a business concept?

In the context of information systems, and in particular during information design, what is the adequate terminology for referring to the views of the business concepts?

E.g., considering the StackExchange system, what is the correct name for the pages about a question, topic, user, etc. Basically, the most important 'information concepts' of the domain. I view these as the core elements of the information architecture project.

Possible names: 'information unit', 'information object', 'view', 'main page', 'anchor page', simply 'page'.

What is the adequate term in the field?
