Liaison Partners

The IPTC maintains liaison relationships with other organisations in the industry.

We currently have relationships with:


IPTC and the DPP (formerly known as the Digital Production Partnership) collaborate on issues relating to standards for media exchange, particularly for the broadcasting industry.


International Standards Organisation (ISO)

The IPTC is a liaison member of ISO on two technical committees:

  • ISO/IEC JTC 1/SC 29: Coding of audio, picture, multimedia and hypermedia information
    • Working Group 1 (JPEG)
    • Working Group 11 (MPEG)
  • ISO/TC 171/SC 2: Document file formats, EDMS systems and authenticity of information



CEPIC, the industry association for the picture licensing industry, has had a liaison agreement with the IPTC since 2023. Previous to the liaison agreement, CEPIC was a member of IPTC.

CEPIC and IPTC collaborate in many areas relating to images and photo metadata.

The annual CEPIC Congress was the host conference for the IPTC Photo Metadata Conference from 2004 to 2019.


Project Origin

The IPTC is on the Steering Committee of Project Origin, an initiative from the news and media industry to bring provenance and authenticity to news content using digital certificates.


Coalition for Content Provenance and Authenticity (C2PA)

The IPTC has an official Liaison Agreement with C2PA, and contributes to the technical specification for content authenticity and provenance which is promoted by both Project Origin and the Content Authenticity Initiative.
