Three systems, overlapping jobs

EXIF is closely associated with camera capture. IPTC fields are widely used for captions, credits and publishing workflows. Adobe’s XMP framework can serialize many namespaces and preserve editing history or rights data.

Key points
  • EXIF: capture and device facts
  • IPTC: newsroom, caption and rights fields
  • XMP: extensible workflow and application metadata

Why a viewer groups fields

Users usually want an answer—location, device, author or software—not a standards lesson. Grouping normalized values by meaning makes the result useful while still offering the underlying namespace and tag.

What this does not prove

A metadata result describes the fields and structures that the supported parser could read. It does not, by itself, prove authenticity, intent, authorship or the truth of the visible scene.
