What is this link I clicked that starts with "http://ns.nuke24.net/"?

ns.nuke24.net isn't an actual website. URLs starting with "http://ns.nuke24.net/" are 'long names' for concepts that can't necessarily be represented by a sequence of bytes. This is mainly useful for naming types and predicates for use in RDF documents.

Ideally, requests to ns.nuke24.net/XYZ would redirect to a page giving information about XYZ. I'm not quite there, yet. In the meantime, you may be able to find something relevant in this directory or in this TEF file.
