I found some great resources related to a more universal definition of a Governance domain model. First there’s: MetaGov and this research collective has - among others 2 subprojects, both experimental tools.
The Metagovernance Project is an interdisciplinary research collective. We build standards and infrastructure for digital self-governance.
Interesting is the paper Modular Politics: Toward a Governance Layer for OnlineCommunities (PDF) where e.g. in par. 3.8 Implementation strategies they show a governance model for social media mentioning Sortition…
Policy Kit
Consider the platforms you use for online communities today. These platforms only offer governance options that are top-down, autocratic, and punitive, involving admins and mods. But what if platforms could provide other types of governance, such as more democratic ones? What if communities could build for themselves the governance that suits their needs and values?
PolicyKit empowers online community members to concisely author a wide range of governance procedures and automatically carry out those procedures on their home platforms. Inspired by Nobel economist Elinor Ostrom, we’ve developed a framework that describes governance as a series of actions and policies , written in short programming scripts.
Community Rule
“For everyone to have the opportunity to be involved in a given group and to participate in its activities the structure must be explicit, not implicit. The rules of decision-making must be open and available to everyone, and this can happen only if they are formalized.” (Jo Freeman, “The Tyranny of Structurelessness”)
Too many of our communities adopt default governance practices that rely on the unchecked authority of founders, admins, or moderators, lacking even basic features of small-scale democracy. The purpose of CommunityRule is to help communities establish appropriate norms for decision-making, stewardship, and culture.
