MSP-1 Namespace Term
msp:id
Declares the canonical identifier for a resource, ensuring consistent reference across AI agents, crawlers, and internal MSP-1 semantics.
Definition
msp:id represents the authoritative, stable identifier for a resource. This IRI-based identifier ensures that AI systems and semantic processors can reliably reference the same entity, even as content evolves or relocates within the site structure.
The term parallels the concept of @id in JSON-LD but is formalized within MSP-1 for clarity,
interpretability, and cross-domain consistency.
Usage
{
"msp:id": "https://example.com/article/example-identifier"
}
