first class datatypes in DHTs are documents and document identifiers.
Everything addressable is a document/identifier pair that needs to be
stored independently, including metadata key/val pairs.

Can I simply retrieve files by their hash/URI, and how does this work in
The Plex is built upon a hash-to-plaintext system which will allow you to
retrieve files, but this is not the Plex's main usage. Instead, the Plex
will allow you to retrieve all sorts of information about a URI. One type
of information, of course, is a representation of the URI, like what you
might get if you typed that URI into a Web browser.
...meaning that they're focused on the same issue of metadata in
decentralized networks that you are, so there's probably relevant
A question for somebody from Plesh: how does the emphasis on serving and
navigating RDF triples affect the topology of the network? My guess is
that you publish the hash of each element of the triple, so users can
address the elements separately or together. A triple of
:emailAddress <mailto:john@...> .
allows the user to search for the hash of John and/or emailAddress and/or
