-[[IPTC]] is a metadata format used in some types of image files, named after the International Press Telecommunications Council, which developed this standard, intended to be used in the news media industry for pictures transmitted in conjunction with news stories with accompanying captions and other information.

-== Format details ==
+IIM stands for ''Information Interchange Model'', and IPTC for ''International Press Telecommunications Council'', the organization which developed this standard. The format is sometimes referred to as '''IPTC-NAA IIM''', because the Newspaper Association of America is also involved in developing these standards. The terms '''IPTC''' and '''IPTC metadata''' are sometimes used to refer to IPTC-IIM, though they have other meanings as well.
-Structurally, IPTC is a sequence of data blocks, which the specification calls "DataSets". Each DataSet contains a 1-byte "record number" and a 1-byte "DataSet number", which together indicate the type of data stored in that DataSet.
+The format has been incorporated into the broader [[IPTC Photo Metadata]] standard, and is now essentially a legacy serialization format for that standard.
-Take note of DataSet {1, 90} (Coded Character Set), which indicates the [[Character Encodings|character encoding]] used in other DataSets.
+== Format details ==
-Multi-byte integers use [[Endianness|big-endian]] byte order.
