How about: Addressable via a URI?

All fine in the "Addressable" context. But, we are talking about Linked 
Data so you need to add:

1. Entity -- anything that could be Named using a URI and serve as the 
Subject of a description
2. Descriptor Resource -- a type of resource that bears/carries the 
description of a Subject.

Then you have:

An addressable resource address (a kind of URI i.e., a URL) that 
resolves to the representation of the description of a Named Subject.

Basically, you are explaining indirection of the form:

SubjectName (a generic URI) -->SubjectDescriptorResourceAddress (a URL) 
-->SubjectDescriptionRepresention (an eav/spo graph) .
