- Category: property

Relates a media object to one of its reified EXIF tags. Non-functional: an image carries many tags. Projects to schema:exifData.

Property shape: object property; gmeow:MediaObject -> gmeow:ExifTag
Practical Pattern

# 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.
