libiptcdata is a library, written in C, for manipulating the
International Press Telecommunications Council (IPTC) metadata stored
within multimedia files such as images. This metadata can include
captions and keywords, often used by popular photo management
applications. The library provides routines for parsing, viewing,
modifying, and saving this metadata. The library is licensed under the
GNU Library General Public License (GNU LGPL). The libiptcdata package
also includes a command-line utility, iptc, for editing IPTC data in
JPEG files, as well as Python bindings.
