# Worked example: tagging is flat-first, reified on demand ( P4). A bare
# gmeow:hasTag covers "this is tagged X". Tags themselves form a SKOS-style poly-
# hierarchy (gmeow:broaderTag / gmeow:narrowerTag / gmeow:relatedTag) inside a
# gmeow:TagScheme. When the PROVENANCE of a tagging matters — who applied it, in
# which scheme — it is promoted to a reified gmeow:Tagging relator binding tagger
# × tagged × tag × scheme, so a contested or machine-applied tag is auditable.

Usage Advice

Use when

• Use in whole-rooted traversals where stating the narrowing direction is the natural one — a broader tag pointing down to its more specific children.

Avoid when

• Avoid asserting it directly when gmeow:broaderTag (its inverse) is the more natural statement; prefer asserting broader and reading narrower by inversion, and avoid it for associative links (gmeow:relatedTag).

How to use

• Read it as the inverse of gmeow:broaderTag; assert explicitly only when the broader-to-narrower direction is the one being authored, and let the reasoner mirror the other direction.

Examples

• ex:tagAnimal gmeow:narrowerTag ex:tagMammal.
