ISO 16684-1:2019, Graphic technology – Extensible metadata platform (XMP) – Part 1: Data model, serialization and core properties

ISO 16684-1 defines two essential components of XMP metadata:

• Data model: The data model is the most fundamental aspect. This is an abstract model that defines the forms of XMP metadata items, essentially the structure of statements that XMP can make about resources.
• Serialization: The serialization of XMP defines how any instance of the XMP data model can be recorded as XML.

In addition, this document defines a collection of core properties, which are XMP metadata items that can be applied across a broad range of file formats and domains of usage.

The embedding of XMP packets in specific file formats and domain-specific XMP properties are beyond the scope of this document.
