But perhaps a *friendly* name is not a requirement. Freenet has
considered a scheme where files would be described by metadata.
The metadata for a file would be a short list of attribute-value pairs
for things like title, author, publication date, keywords, etc. You would
search using these fields, and then get back a content hash.
MojoNation works much the same way. You search on metadata and get back
a content hash like the one I showed earlier.
These systems suggest that item (1) in the three service model may be
modified by having metadata in place of a friendly name.
You could also imagine systems which allow direct searches of the text
of documents (similar to what we have on the web with search engines)
and return a content hash key. These would have neither friendly names
nor metadata.
