Graphic technology — Extensible metadata platform (XMP) — Part 1: Data model, serialization and core properties
This document 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.

ISO (the International Organization for Standardization) is a worldwide federation of national standards

through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

Introduction
This document specifies a standard for the definition, creation, and processing of metadata that can be
applied to a broad range of resource types. The Extensible Metadata Platform (XMP) was introduced
by Adobe Systems Incorporated in 2001 and has since established itself as a critical technology for
improving business efficiency in many industries. The Adobe Systems XMP Specification Part 1
version of July 2010 is the basis for this document. Establishing this document ensures the stability
and longevity of its definitions and encourages broader integration and interoperability of XMP with
existing standards.
Metadata is data that describes the characteristics or properties of a resource. It can be distinguished
from the main content of a resource. For example, for a word processing document, the content includes
the actual text data and formatting information, while the metadata might include properties such as
author, modification date, or copyright status.
Some information could be treated as either content or metadata, depending on context. In general,
metadata is useful without regard for a resource’s
