EXIF Tag

• Category: class
• Defined by: gmeow:slices/images
• Box roles: TBox role (What is this?)

A reified EXIF metadata tag of a media object — a tag identifier (gmeow:exifTagId, e.g. 'FNumber'), its value (gmeow:exifTagValue, e.g. 'f/2.0'), and a human-readable label (rdfs:label, e.g. 'Aperture'). The schema:PropertyValue shape: reification keeps each tag's id/value/label paired correctly and lets an OPEN, camera-defined EXIF set round-trip losslessly to schema:exifData.

Structure

Subclass of: gufo:FunctionalComplex

Practical Pattern

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