What is XMP metadata?

A practical guide to XMP packets, image metadata inspection, safe merging, and export verification.

Definition

Extensible Metadata Platform (XMP) is an XML-based model for structured metadata that can be embedded in supported media containers.

Example

A JPEG commonly stores XMP in an APP1 segment. A PNG can store it in an iTXt chunk using the Adobe XMP keyword.

How to inspect

Use Media Inspector to view a friendly summary and the escaped raw packet. Structural warnings identify malformed or duplicate packets.

How this product uses it

The Prepare workflow merges selected compliance values into supported JPEG and PNG XMP rather than replacing unrelated subjects.

Limitations

Applications and export pipelines may remove or rewrite metadata. Always inspect the final artwork that will be uploaded.
