The XMP specification describes techniques for how to embed the metadata in JPEG, TIFF, JPEG2000, GIF, PNG, HTML, PostScript, PDF, SVG, Adobe Illustrator, and DNG files. These are known as "IPTC headers." In 2001, Adobe introduced something called "Extensible Metadata Platform" (XMP), which is an XML schema for the same types of metadata as IPTC. In 1979, the IPTC defined a set of metadata attributes to be applied to images, and in 1994 Adobe defined a specification for actually embedding the metadata into digital image files. It develops and maintains technical standards for improved news exchange that are used by virtually every major news organization in the world. IPTC metadata was developed by the International Press Telecommunications Council, which is a consortium of the world's major news agencies and news industry vendors. This information was taken from the Exif entry at Wikipedia entry, which see for more information.

Digital cameras will record the current date and time and save this in the metadata. Tags defined in the Exif standard include: There is a large overlap between the tags defined in the TIFF, Exif, TIFF/EP and DCF standards. ![]() The Exif tag structure is taken from that of TIFF files. The specification is not maintained by any industry or standards organisation, but it remains in almost universal use by camera manufacturers. Version 2.1 of the specification is dated June 12, 1998, and version 2.2 is dated April 2002 and is also known as Exif Print. It is not supported in JPEG 2000, PNG, or GIF.Įxif was created by the Japan Electronic Industries Development Association (JEIDA).

It is displayed in Xnview's preview area in its own tab according to the kind of metadata used. It also can include commentary and embedded thumbnails. Metadata is information about the image and/or file which cameras and image-generating programs attach to images to inform the user of a diverse number items such as: Date and time of composition, camera settings. In general, metadata is "data about data." In the case of XnView, metadata refers to information about images and image files.
