At its heart, GitRules is a platform for augmenting the collaborative software development workflow with governance and economic mechanisms — called protocols.
GitRules supports multiple policies which can be activated on individual issues and pull requests by applying a protocol-specific GitHub label to the issue or pull request.
In our latest release, v2.1.1, we introduced the Plural Management Protocol — described in our research paper — whose protocol label is gov4git:pmp-v1.
