Image Region

A region within an image — a structural part of a gmeow:MediaObject, described by a gmeow:RegionSelector that encodes its boundaries. The counterpart of ContentSegment for visual media: a face, an object bounding box, a polygon, or a pixel mask. Carries a human-readable gmeow:regionLabel.

Structure

Subclass of: gmeow:InformationObject

Practical Pattern

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

# Worked example: image metadata at three layers. EXIF technical tags
# (gmeow:hasExifTag) record how the bytes were captured. A gmeow:ImageRegion with
# a typed gmeow:RegionSelector pins WHERE something is in the frame (a fractional
# bounding box). And a gmeow:DepictionUsage makes "this image depicts X" a
# PERSPECTIVAL act, not a bare fact: it records the subject, the context (candid /
# portrait / childhood …), and WHOSE authority asserts the depiction — so the same
# photo can be a "family" depiction to one audience and a "work" depiction to
# another, without either being privileged.
