What is the IPTC standard?

The IPTC-NAA standard describes a method for storing information, image and graphic files.

This method is widely used among others in the TIFF and JPEG are used, which are now used by all digital cameras. The IPTC-NAA standard has been defined already in 1990, well before the mass-market boom of said graphic formats. The basic idea is quite simple: photos, here today, especially with a digital camera captured images should be provided with additional text information. This information can be in the next step, for example through special programs or even read now through online services and processes.

Originally the method was designed for the professional press, which would make her countless material by the insertion of so-called "metadata" (additional information) easier to find. Very important information to the respective author (keyword image rights) were the captions and keywords (tags). Similarly, the IPTC-NAA standard location (today about GPS modules of modern digital cameras easy to determine) and the date and time of each recording is stored.

Since 2003, an expanded version of the IPTC-NAA standards is used, which stores the information in XMP format. Since 2004, remains the core defined IPTC Photo Metadata Standard. From the daily use of digital cameras and related photo services, the concept is here to stay: Popular photo archives as "Flickr" or "Picasa" show after upload a photo important information such as location, name of the photographer or the capture time automatically by reading IPTC metadata to. Were it not for this technique, the author would have to enter all the information by hand.
