The XMP specification became an ISO standard and is not proprietary anymore. Initially, Adobe released source code for the XMP SDK under a license called the ADOBE SYSTEMS INCORPORATED — OPEN SOURCE LICENSE. The compatibility of this license with the GNU General Public License has been questioned. The license is not listed on the list maintained by the Open Source Initiative and is different from the licenses for most of their open source software. On May 14, 2007, Adobe released the XMP Toolkit SDK under a standard BSD license. On August 28, 2008, Adobe posted a public patent license for the XMP. Adobe continues to distribute these documents under the XMP Specification Public Patent License. History XMP was first introduced by Adobe in April 2001 as part of the Adobe Acrobat 5.0 software product. On June 21, 2004, Adobe announced its collaboration with the International Press Telecommunications Council. In July 2004, a working group led by Adobe Systems' Gunar Penikis and IPTC's Michael Steidl was set up, and volunteers were recruited from AFP (Agence France-Presse), Associated Press, ControlledVocabulary.com, IDEAlliance, Mainichi Shimbun, Reuters, and others, to develop the new schema. The "IPTC Core Schema for XMP" version 1.0 specification was released publicly on March 21, 2005. A set of custom panels for Adobe Photoshop CS can be downloaded from the IPTC. The package includes a User's Guide, example photos with embedded XMP information, the specification document, and an implementation guide for developers. The "User's Guide to the IPTC Core" goes into detail about how each of the fields should be used and is also available directly as a PDF. The next version of the Adobe Creative Suite (CS2) included these custom panels as part of its default set. The Windows Photo Gallery, released with Windows Vista, offers support for the XMP standard, the first time Microsoft has released
