---+ DFS: Federative, disconnected, peer-to-peer filesystem for Grid4All ---++ Overview [[http://www.grid4all.eu][Grid4All]] is an FP6 project funded by the European Union. The main objective of the project is to research and develop a _democratic_ Grid, that enables individual users to draw upon internet resources for their applications without having to invest in IT infrastructure. Read [[AboutGrid4All][about Grid4All]]. Our team is involved in Grid4All data storage, researching and developing DFS, a peer-to-peer distributed filesystem with a modern and _democratic_ character, that is most suitable for the project. Currently, it is in an early prototype status. The most prominent features of DFS are: * [[P2P][Peer-to-peer]], web-like navigation. Other's computers are accessible just by typing their address in the path. * Federation of files. You can create workspaces and populate them by linking in files anywhere on the internet. * Federation of storage. Peers can contribute storage to each other, creating storage pools. Peers create files using this distributed pooled storage. * Disconnected operation. Files are locally cached and remain available when disconnected from the network. Synchronisation is done automatically, if conflicts do not occur. * Notifications for file modifications and [[http://en.wikipedia.org/wiki/Publish/subscribe][publish-subscribe]] messaging * Integration with the OS. DFS can be mounted in [[http://www.linux.org][Linux]] and [[http://www.apple.com/macosx][MacOS]].
