Camlistore is a set of open source formats, protocols, and software for modeling, storing, searching, sharing and synchronizing data in the post-PC era. Data may be files or objects, tweets or 5TB videos, and you can access it via a phone, browser or FUSE filesystem.
Implementation of IPFS, a global, versioned, peer-to-peer filesystem that seeks to connect all computing devices with the same system of files. It combines good ideas from Git, BitTorrent, Kademlia, SFS, and the Web. It is like a single bittorrent swarm, exchanging git objects.
Note: It is possible that some search terms could be used in multiple areas and that could skew some graphs.
