ITPC started out as both a file structure and set of metadata attributes that can be applied to text, images and other media types. It was developed in the early 1990s by the International Press Telecommunications Council (IPTC) to expedite the international exchange of news among newspapers and news agencies.
A subset of ITPC found broad worldwide acceptance as the standard embedded metadata used by news and commercial photographers for information such as the name of the photographer, copyright information and the caption or other description.
Adobe’s XMP has largely subsumed the Interchange image attributes in the IPTC Core schema for XMP, so sometimes the image attributes are doubled up between the original IPTC file elements, and the XMP iteration. Most image manipulation programs keep the XMP and non-XMP IPTC attributes synchronized, so they appear in Premiere Pro without additional effort.

Media Composer does not read or display ITPC metadata directly but you an add ITPC metadata to Media Composer bins via a piece of software like MetaCheater to extract the ITPC metadata from the stills. Once extracted, add the metadata to a tab delimited Avid ALE file. Import the ALE and batch import the stills. This will merge the metadata in the bin with the still image. For more information on ALE, try this tutorial.
