jetring is a collection of tools that allow for gpg keyrings to be maintained using changesets. It was developed with the Debian keyring in mind, and aims to solve the problem that a gpg keyring is a binary blob that's hard for multiple people to collaboratively edit.

With jetring, changesets can be submitted, reviewed to see exactly what they will do, applied, and used to build a keyring. The origin of every change made to the keyring is available for auditing, and gpg signatures can be used to further secure things.

jetring is available in git at git://

It's also in Debian.
