source tier

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

The bibliographic tier of the source referenced by a citation — primary, secondary, or tertiary. Non-functional: competing tier assessments coexist (Principle 9).

Structure

Property shape: object property; gmeow:CitationAct -> gmeow:SourceTier

Practical Pattern

Use gmeow:sourceTier from gmeow:CitationAct to gmeow:SourceTier when the relationship itself belongs in the native GMEOW graph.

# Worked example: grading citations as evidence. The evidence slice hangs
# quality dimensions on a gmeow:CitationAct (from the citations slice): its
# gmeow:hasEvidenceClass, gmeow:sourceTier (primary/secondary/tertiary),
# gmeow:sourceIndependence and gmeow:coverageDepth together decide whether the
# citation gmeow:supportsNotability. The Wikipedia-notability discrimination falls
# straight out: independent + secondary + significant coverage SUPPORTS it; a
# routine self-originated passing mention does NOT — same predicate, graded.

# --- Strong evidence: an independent trade-press feature with depth → supports.
#     The subject (citingEntity, generic Entity) is supported by the cited work
#     (citedEntity, a CreativeWork): gmeow:intentSupports reads "the cited work
#     supports the citing entity", and the evidence dimensions grade that support.

Usage Advice

Use when

• Use to record the primary/secondary/tertiary bibliographic tier of a cited source as part of a notability assessment (Axis B).

Avoid when

• Avoid using it for the source's independence (gmeow:sourceIndependence) or its coverage depth (gmeow:coverageDepth), and avoid using tier as a proxy for evidential warrant; the tier is orthogonal to how strongly the citation verifies the fact.

How to use

• Point the gmeow:CitationAct at a gmeow:SourceTier individual; combine it with gmeow:sourceIndependence and gmeow:coverageDepth so the solver can weigh notability, and keep competing tier assessments as coexisting claims (Principle 9).
