Tagging

• CURIE: gmeow:Tagging
• IRI: https://blackcatinformatics.ca/gmeow/Tagging
• Category: class
• Defined by: gmeow:slices/tags

A reified tagging act — a gufo:Relator mediating a tagged resource, a tag, a tagger, and optionally a scheme and time interval. Bears provenance (gmeow:wasAttributedTo), confidence (gmeow:confidence), and suppression (gmeow:displayable false for retraction without deletion — Principle 10). Structurally the NameUsage/IdentityFacet idiom wearing a different hat, inheriting time-scoping, confidence-weighting, and retract-without-delete for free. The canonical form when the act of tagging must itself be a node; the flat shortcut is gmeow:hasTag.

Structure

Subclass of: gufo:Relator

Practical Pattern

Use gmeow:Tagging as a specialized kind of gufo:Relator. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.

# 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 when the act of tagging must itself be a node — to record who tagged, when, under which scheme, with what confidence, or to retract a tag without deleting it (gmeow:displayable false).

Avoid when

• Avoid for the ordinary 80% case where a bare label suffices (use the flat gmeow:hasTag, optionally with RDF-star annotations); reify only when provenance, period, or suppression must be first-class.

How to use

• Mint the relator and fill its roles — gmeow:taggingTagged, gmeow:taggingTag, gmeow:taggingTagger, optionally gmeow:taggingScheme and gmeow:taggingInterval — then carry provenance, confidence, and displayable on the relator node; gmeow:hasTag pairsWith Tagging as the promotion target.
