endorses

• CURIE: gmeow:endorses
• IRI: https://blackcatinformatics.ca/gmeow/endorses
• Category: property
• Defined by: gmeow:slices/trust
• Box roles: RBox role (What is this?)

A convenience shortcut recording that one agent vouches for another. Deliberately NOT symmetric (endorsement is directional) and NOT transitive (trust must not propagate inside the reasoner — that is the metric the perspectival TrustAssertion bounds). Use gmeow:TrustAssertion for leveled, dated, perspectival trust.

Structure

Property shape: object property; gmeow:Agent -> gmeow:Agent

Practical Pattern

Use gmeow:endorses from gmeow:Agent to gmeow:Agent when the relationship itself belongs in the native GMEOW graph.

# Worked example: the PGP web of trust. Trust is decentralized and
# relational: agents gmeow:holdsKey cryptographic keys; one agent's
# gmeow:Certification signs another's key (a key-signing, binding key↔identity);
# and a gmeow:TrustAssertion records how much a trustor trusts a trustee AS AN
# INTRODUCER (gmeow:trustLevel + gmeow:introducerDepth — how far transitive trust
# may flow). gmeow:endorses is the lightweight, keyless vouch. No central
# authority: trust is asserted pairwise and composed.

Usage Advice

Use when

• Use as the flat shortcut for a directional vouch between two agents when level, date, and introducer parameters do not matter — the reify-on-demand companion of gmeow:TrustAssertion.

Avoid when

• Avoid when the trust is leveled, dated, or holds an introducer depth (promote to gmeow:TrustAssertion) and avoid expecting symmetry or transitivity — endorsement is directional and never propagates A→B→C inside the reasoner.

How to use

• Assert gmeow:endorses from endorser to endorsee for the lightweight case; promote to a gmeow:TrustAssertion the moment you need a trust level, validity window, or introducer parameters, and compute any transitive validity in the projection layer.
