IPTC Core & Extension = the IPTC Photo Metadata standard

IPTC Core and IPTC Extension are two metadata schemas developed by the IPTC for professional use with a focus on news and stock photos.
The technical implementation of the metadata is employing Adobe's XMP technology.

  The IPTC-PLUS Photo Metadata Toolkit for Adobe CS products.
It includes:
* for the IPTC Core and IPTC Extension file-info panels built into CS5 to CS6: a comprehensive User Guides for both schemas (Download as single PDF document)
* a plug-in IPTC-PLUS Metadata Panel for Bridge CS3/CS4 for the IPTC Core, IPTC Extension and the PLUS metadata - with a comprehensive User Guide for all fields
* example images
Find more about it and download it from the Toolkit page.

IPTC Core and Extension are published together as IPTC Photo Metadata Standards. Its latest version of July 2010 includes the IPTC Core 1.1 and the IPTC Extension 1.1 specifications.

IPTC Core

The IPTC Core provides a set of basic metadata to describe and manage images:
  • The IPTC Core schema is made for a smooth and straightforward transfer of metadata values from the IIM-based IPTC fields to the XMP framework
  • It includes a specification on how to synchronise IPTC-IIM field values with the new IPTC Core - back and forth.
  • "Custom panels" for Adobe CS2 and CS3 to provide a simple user interface to all IPTC Core fields - with a comprehensive User Guide.

The IPTC-PLUS Photo Metadata Toolkit for Adobe CS includes a user guide for all IPTC Core fields in Adobe products from CS3 to CS6.

 

 

Version 1.1 specifications

IPTC Core 1.1 was approved in July 2008 and its specification is published as part of the IPTC Photo Metadata Standards spec document.

An Errata Page provides a list of errata found in the spec document after its release.

Version 1.0 specifications

The "IPTC Core" version 1.0 specification was approved by the IPTC in 2004 and the specification document and additional supporting material is available:

This material can be downloaded as either a full package or a "Photoshop CS panels only"

A severe problem was found with Photoshop 7.1 and CS 1 (aka V 8): Data input to one of the IPTC Core fields in the built-in Description or Origin panel are not saved to the XMP Packet. Please DOWNLOAD this package to fix the problem. - be aware it does not apply to Photoshop CS 2 or CS 3.

 

IPTC Extension

The IPTC Extension schema is a supplemental schema to the IPTC Core. It provides:

  • Fields to provide additional information about the content of the image, e.g. name or locatation shown in the image, an organisation or event featured by the image, ... and more
  • Fields to improve administration, like e.g. for registering the image with a registry
  • Fields for cultural heritage photos, including a title, a creator, a creation date and information about the source of an artwork or object shown in the image
  • Fields to precisely define the licensing terms and the copyrights of a photograph.

The IPTC-PLUS Photo Metadata Toolkit for Adobe CS includes a user guide for all IPTC Extension fields for Adobe products from CS3 to CS6 and adds IPTC Extension fields to CS3 and CS4 by a plug-in panel.

 

Version 1.1 specifications

IPTC Extension 1.1 was approved in June 2009 and its specification is published as part of the IPTC Photo Metadata Standards specification document.

An Errata Page provides a list of errata found in the spec document after its release.

For both standards

XMP technology

Adobe's Extensible Metadata Platform (XMP) is a technology that allows you to embed metadata into the file itself. With XMP, desktop applications and back-end publishing systems gain a common method for capturing, sharing, and leveraging this valuable metadata.

Software created by Adobe but also many more software vendors is enabled to process XMP metadata as XMP is built on a set of public specifications. You may download them from Adobe's XMP pages: www.adobe.com/products/xmp/

Note: XMP is Adobe's sole intellectual property and not IPTC's.
