First, there's the urn:uuid: namespace (as per RFC 4122), which allows for content-based (MD5, SHA-1) identifiers, similar to those employed in P2P filesharing networks (including BitTorrent, Freenet, and GNUnet.) Second, there're (non-standard, though, as it seems, widely used) urn:btih: (and, similarly, urn:sha1:, etc.) URI's that, I believe, were intended for registration as URN namespaces. However, I was since pointed to the proposed ni: URI scheme [1], which appears to be better suited to the task of P2P content identification. (To clarify: while the present gnunet: URI's are indeed application-specific, the primary payload of such URI's are base32hex-encoded SHA-512 digests over arbitrary content. While the ni: scheme as proposed doesn't allow for such, it provides the relevant extension mechanism, which may allow for gnunet: URI's, as well as urn:btih: and freenet:, to be superseded with ni: ones in the future.)
