Is there a database filsystem for linux?
I call "database filesystem" a filsystem that can associate a set of "classes"
to every file:
file cantaperme.mp3 -> [music, ]anime, noir, ost, italian
file wallpaper1.png -> [image, ]anime, noir, wallpaper
file review.html -> [hypertext, ]anime, noir, review[, english]
and so on.
Once done, I doesn't matter where the file is: I [should be able to] make
a directory called, for example, "%%anime, wallpaper%%" ("%" is an example,
just to let the os know that the name contains a command and is not the
real directory name, specified in some other way) and I find inside the
newly created directory every file with "anime" and "wallpaper" inside the
"classes" field (in other words: every wallpaper about anime).
I could also make a directory called "%%anime, noir%%&&canta&&" (again,
"&" is an example: it tells the os to look only for files containing the
string between && and && in the name) to find every file containing noir
and anime in the classes field and containing "canta" inside the name.
Of course the name of the resulting directory could be specified after the
last "%%" or "&&" ("%%anime, music, ost%%&&ogg&&Music files from anime OSTs
compressed with ogg vorbis").
Similar things can be done with symlinks, but once the FS is a DB many more
possiilities are opened.
I know Reiser is good to index files (in a future release, I read something
in the site www.namesys.com), while XFS can have multiple stream for every
file.
Moreover, I'd like to see it under linux than under win! (I think they will
have it before 2005).
Maybe you people know a DB FS ready to use or an experimental one.
Thanks a lot!
