has license

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

Relates an entity (a work, dataset, software project, …) to a licence granting rights in it (dcterms:license; schema:license). Named gmeow:hasLicense — gmeow:license is reserved for the mapping-DSL set-license datatype property.

Structure

Property shape: object property; gmeow:Entity -> gmeow:License

Practical Pattern

Use gmeow:hasLicense from gmeow:Entity to gmeow:License when the relationship itself belongs in the native GMEOW graph.

# 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 as the flat-first link from any licensable asset to the gmeow:License granting rights in it (dcterms:license, schema:license) — the common case, the flat half paired with gmeow:License.

Avoid when

• Avoid the reserved gmeow:license datatype property (that is the mapping-DSL set-license, not this rights link) and avoid promoting to a gmeow:RightsStatement unless explicit permissions, prohibitions, or duties are needed.

How to use

• Assert one gmeow:hasLicense per granting licence pointing at a gmeow:License relator; the License carries the SPDX id, family, parties, and validity. The pairsWith link makes the promotion path to a RightsStatement machine-visible.
