Manipulating CTS URNs

In addition to extracting component parts of a URN, you can manipulate those components to create valid new URNs. New URNs necessarily have a different meaning, but because cite facilitates building URNs from the components of another URN, semantically related URNs can be a automatically assembled.

Supported manipulations

1. To refer to the cited text as a whole, we can remove the passage component of a URN.
2. To generalize a URN referring to a version or exemplar, we can reduce the work component to the notional work level, while keeping the passage reference unchanged.
3. To generalize a URN referring to a specific exemplar, we can reduce the work component to the version level (edition or translation), while keeping the passage reference unchanged.
4. To generalize a URN with a subreference, we can reduce the passage reference to refer to the citable node, while keeping the work reference unchanged.
