# Worked example: rights are flat-first, promoted on demand ( P4). The
# common case is a single gmeow:hasLicense + gmeow:hasCopyright edge — no relator
# needed. Only when the deontic RULES matter (who may do what, under which duty,
# what is forbidden) is the flat form PROMOTED to a gmeow:RightsStatement bearing
# the ODRL-superset trio: gmeow:Permission / gmeow:Prohibition / gmeow:Duty, each
# over an open gmeow:RightsAction value. A licence is itself an Agreement, aligned
# to CC/ODRL by reference (spdxLicenseId, licenseFamily) — never owl:sameAs (P5).

Usage Advice

Use when

• Use for an obligation that must be discharged — attribute, share-alike, retain-notice, obtain-consent — typically as a condition of a permission (the odrl:Duty / odrl:obligation rule, CC REL cc:requires).

Avoid when

• Avoid for an allowed or forbidden action (use gmeow:Permission / gmeow:Prohibition); the three rule kinds are pairwise disjoint, so a duty is never also a permission.

How to use

• Mint one Duty per obligation with a single gmeow:ruleAction, link it from the conditioned permission with gmeow:hasDuty, and use it as the gmeow:ruleConsequence of a duty or prohibition for deontic chaining.

Examples

• ex:mustAttribute a gmeow:Duty; gmeow:ruleAction gmeow:actionAttribute.
