LaputaFS (Userland Pure Tag File System) aims to be a full tag-based file system: a file is characterised not by a name and a path, but by a group of tags (or labels) such as "Work", "Project X", "Music", "Documentation"…

The files of a physical file system (e.g. an ext3 partition) are indexed and presented them under a tag-oriented FUSE-based structure. They can then be accessed through this virtual file system, using standard system commands (cd, ls, cp, mv…).

LaputaFS is (not so much) implemented in C^WPerl. Currently, it uses a SQLite database to store tags and file information, but it is planed to support other DBMS someday (at least PostgreSQL and probably MySQL).

Please read the FAQ if you are a romanic language-speaker shocked by the name of this project.
