It's git. You can trivially keep an entire copy the databases trivially. It
can be hosted in many places. We'd have to redo the issue tracking, but
bugtracking systems are not exactly hard anymore.

Correct, that is intentional. The database is just the ID and
assignee/requester/etc. THe Database schema would never be close to
correct/complete so I decided not to have one. The Artifacts Database
contains all that data, there will be a JSON file(s) with some semi
structured data (e.g. OSVDB, X-Force IDs, original researcher/etc.) and
then any artifacts (e.g. a copy of a security report, patch file,
whatever).

See above. That's the whole point of the artifacts database. Please reread
my original email maybe?

I am of course open to feedback, but please actually go to
https://github.com/distributedweaknessfiling/ and see what we're doing
first before assuming we aren't doing certain things (like making sure the
artifacts associated with a security vuln don't disappear).
