ISO 16684, the extensible metadata platform (XMP) specification, is the ISO version of a technology Adobe Systems developed in 2001 as part of Acrobat.
The technology was originally introduced in order to make it easier to describe the properties of a digital dataset, such as an electronic document or image, and thus to facilitate automated processing. With XMP, digital systems can populate databases, respond to software triggers and provide an interface to other systems so that the same data can be used in many places. At the time of its introduction, XMP was seen as a much more sophisticated alternative to hot folders, which it has now largely replaced. Adobe passed it on to ISO in 2010 and the current standard was last formally reviewed in 2017. However, given the superfast nature of the software industry, the document is under constant review within ISO TC130 (Graphics technology), the ISO committee responsible for it.
