In order to guard against database corruption, I suggest that any important file attributes be stored as xattrs on the file (in addition to within the index). Whether the file is a landmark version and maybe MIME type is important. Preview is not important. Tags might be important. The most trustworthy database is the kind you can 'rm -rf' and regenerate.

If you haven't already, consider taking a look at the Linux version of Venti as well, it is available in the plan 9 from user space suite: http://swtch.com/plan9 Also consider using 9P instead of FUSE as it can give you implicit distributed file system capabilities -Ericvh 15:34, 21 March 2008 (EDT)
- I will probably consider 9P for a 2nd implementation, mostly due to API issues. I'm not interested in building a distributed file system, however. CScott 13:15, 9 May 2008 (EDT)

Reiser4 comparison
