I was searching and discovered that if you search for "urn sha-1 hash"
you get a considerable number of references to URI schemes and URN
namespaces that have been proposed that use cryptographic hashes to
identify objects.  Some of them have a history of usage.

A particularly amusing one starts thus:

    Existing standards for hash-based URN schemes

    TL;DR: Before inventing a new URI scheme, see if there's already one
    in use that does what you need.
