Hi Jensen and all,

Actually, I would suggest the following structure:

- Basic Concepts
  - Information Resource
  - Entity
  - Entity Property
  - Entity Domain
- Property Map  <====  Explain how property map works and the motivations
for exporting and aggregating entity domains
  - Resource-Specific Entity Domain
  - Aggregated Entity Domain
  - Resource-Specify Entity Property

The two top-level sections (basic concepts and property map) are similar to
Sec 2 (Terminology) and Sec 5 (Network Map) in RFC 7285.

In the basic concepts section, we are describing what already exists even
without the property map service.

In the property map section, we are "inventing" concepts that serve certain
practical purposes (e.g., provide indications of what entities/properties
can be queried, aggregate entities/properties).

Having said that, it is OK with me that we keep the current structure or
only make some small changes if it requires too much work.

Best,
Kai
