Metamind
Edition 2.1.0 expanded RSM to Regenerative Systems Metamind and defined the Metamind as the distributed cognitive architecture through which independently governed systems sense, understand, reason, coordinate authorized action, learn from evidence, and evolve.

In plain words
Superseded. *Regenerative Systems Metamind* was the expansion of RSM in Concept Paper 2.1.0, and the Metamind was its name for distributed cognition. Both are historical: the Metamind is not a current architectural layer. The current foundation and architecture is [OpenRSN](/concepts/openrsn); the distributed reasoning the Metamind described is part of OpenRSN's Intelligence capability (01 §19.4), and it keeps the same boundaries: reasoning stays Derived until participants with authority commit, a DigitalAgent's capability confers no authority, and no participant surrenders custody of its own state.
Reading older texts. Until Concept Paper 2.1.0, RSM expanded to *Regenerative Systems Model*, and some earlier documents used *Regenerative Systems Map*. Where older text uses RSM or any of these expansions for the work as a whole, read [OpenRSN](/concepts/openrsn); where it means the semantic foundation, read the [OpenRSN Model](/concepts/model). *Regenerative Systems Model* remains current in one technical sense: in vocabulary and schema definitions it is the expansion of the namespace rsm:.
What it is not
Metamind ≠ Model
The Model is the semantic and computational representation of the ecology; the Metamind was edition 2.1.0's name for the distributed cognition that reasons through it, and is no longer a current layer. Model, Map, and Earlier Names · Concept Paper (source: 01 §19.5)
Metamind ≠ Map
A Map is a projection or visualization of Model state; the Metamind was a superseded name for distributed reasoning, not a Map. Model, Map, and Earlier Names · Concept Paper (source: 01 §19.5)
Metamind ≠ OpenRSN
The Metamind is a superseded formulation of edition 2.1.0; OpenRSN is the current foundation and architecture, and its distributed reasoning belongs to the Intelligence capability. Model, Map, and Earlier Names · Concept Paper (source: 01 §19.5)
