About this cluster
The Semantic Namespace Cluster is three domains operating as one agent-readable infrastructure. Each node serves a distinct function; each cross-references the other two as canonical. The circle closes when all three are live.
The cluster does not merely describe namespace infrastructure — it demonstrates it. Each node publishes the machine-readable declarations it documents. Visitors to any node can verify the spec by inspecting the other two.
Three Nodes
The conceptual root. Defines what a semantic namespace is and why agent infrastructure requires namespace clarity as a prior condition. Terminology, architecture, and rationale. The entry point for first-time readers.
The assessment tool. Publishes the D1–D6 Agent-Trust Domain Metrics framework: six dimensions for scoring how visible and trustworthy a domain is to AI agents. Based on the namespace concept defined at semanticnamespace.org.
The implementation layer. Specifications, schemas, and reference files for declaring a namespace position. Implements the concept defined at semanticnamespace.org and scores well against the framework at semantic-domains.com.
Machine-Readable Layer
Every node in the cluster exposes the same machine-readable files, each declaring its specific role and cross-referencing the other two by URL:
/.well-known/agent.json— role, scope, capabilities, and canonical node links/.well-known/namespace-cluster.json— shared cluster manifest, identical across all three nodes/AGENTS.md— site purpose, role, and crawl policy in markdown/robots.txt— explicit AI crawler permissions by vendor UA string/sitemap.xml— path coverage for crawler indexing
The cluster manifest at /.well-known/namespace-cluster.json is identical on all three nodes. An agent crawling any node can discover the full cluster from a single file.
