international press telecommunications council (IPTC)
International Press Telecommunications Council (IPTC), Exchangeable Image File(EXIF) and the Extensible Metadata Platform(XMP) are metadata standards for archiving digital photos.
The IPTC specifications evolved from the Information Interchange Model( IIM) and were developed by the International Press Telecommunications Council (IPTC) together with the Newspaper Association of America( NAA). They are used to exchange metadata for multimedia objects. The metadata can be used equally for the description of digital photos and graphics, videos and audios. They are stored in a file area defined by the standard and contain relevant information such as copyright, title, date taken, location taken, exposure details, photographer's name, keywords, notes, comments, and much more. A total of over 30 data fields are available for entries. IPTC files are part of the XML-based Extensible Metadata Platform (XMP).
IPTC is used in the professional and semi-professional sector, in press, advertising and picture agencies, in publishing houses, radio and television stations.
The IPTC standard is used in image databases and image archives to tag photos with keywords and other important data. Using this information stored in the image files, operators can directly access the image information.
While IPTC files contain notes and comments about the photos, EXIF is about photo technical information and Extensible Metadata Platform (XMP) stores metadata about photos and their processing steps.
