MSP-1 Namespace Term
msp:canonical
Identifies the preferred authoritative URL representation of a resource when multiple URLs, copies, mirrors, variants, or representations may exist.
Definition
msp:canonical declares the preferred authoritative URL representation for a resource. It helps agents, validators, and implementation tools resolve ambiguity, consolidate references, and identify the primary representation of a resource.
The canonical term is related to url, but it is not interchangeable with it. url identifies a resource location; canonical identifies the preferred authoritative URL representation when more than one representation may exist.
Usage
{
"msp:canonical": {
"url": "https://msp-1.org/spec/canonical/"
}
}
Canonical declaration with reason:
{
"msp:canonical": {
"url": "https://photographyselect.com/lighting-guide/",
"reason": "This is the officially maintained and updated version."
}
}
The canonical term identifies the preferred authoritative URL representation. It does not declare trust level, verification status, or compliance.
