Extensible Metadata Platform

from Wikipedia, the free encyclopedia

The Extensible Metadata Platform ( XMP ) is a standard for metadata , thus with a photo, for example, data on the photographer, the equipment used and the recording location, embedded in digital media or as a sidecar file to define. It was published by Adobe in 2001 and was first integrated into Acrobat Reader 5. In February 2012 the core part of the XMP specification appeared as ISO standard ISO 16684-1.

XMP is based on open standards and embeds the formal language RDF ( Resource Description Framework ) published by the World Wide Web Consortium in binary data. The aim is to integrate the metadata in different applications according to a uniform scheme so that the files can still be read by other programs. The format is supported by all Adobe products, by software from other manufacturers and also by providers of content management systems.

The original specification and an SDK are available under an open source license . This was initially rated as not free enough, whereupon the SDK from version 4.1.1 is available under a BSD license . The XMP core part in the form of the ISO standard ISO 16684-1 is available for a fee from the ISO.

XMP Toolkit

Adobe provides the XMP Toolkit SDK , which consists of two program libraries:

  • XMPCore (used to create and modify the metadata based on the XMP standard)
  • XMPFiles (used to integrate the XMP information into various file formats)
