A resource may declare a namespace: a URI prefix, such as https://w3id.org/spaces/example/r/vocabulary/, under which the things belonging to it are minted. Anything with a URI under that prefix is a part of the resource, and gets a page of its own, hosted within the resource's page, showing what the network knows about it.

A part's page is put together from the nanopublication that introduced it, which must have been published by a member of the space. Links to a part from anywhere on Nanodash lead to that page, so the namespace is also what makes a resource's terms, entries or paragraphs navigable rather than bare URIs.
