Specification catalogue

Find the structure your AI needs.

A live registry of versioned meta-model specifications. Search by family, category, industry, domain, name or tags; storage formats and interfaces remain independent.

The catalogue holds the whole Thing Registry: every registered thing an agent might meet, marked TODO until its governed specification is written. AISMM, PLMM and prior World Model assemblies remain here as examples.
