Overview
IIM attributes are widely used and supported by many image creation and manipulation programs. Almost all the IIM attributes are supported by the Exchangeable image file format (Exif), a specification for the image file format used by digital cameras.
IIM metadata can be embedded into JPEG/Exif, TIFF, JPEG2000 or Portable Network Graphics formatted image files. Other file formats such as GIF or PCX do not support IIM.
IIM's file structure technology has largely been overtaken by the Extensible Metadata Platform (XMP), but the IIM attribute definitions are the basis for the IPTC Core schema for XMP.
