IPTC Photo Metadata

1. Overview

IPTC Photo Metadata provides data about photographs and the values can be processed by software. Each individual metadata entity is called a property and they are grouped into Administrative, Descriptive and Rights-related properties.

IPTC Photo Metadata properties have photo specific definitions that are widely supported by imaging software.

IPTC Photo Metadata aligns with other IPTC metadata standards made for media items of any media-type. Thus they integrate with media-type agnostic digital asset management systems.

The IPTC Photo Metadata (October 2016) specification is split into two different schemas:
  • The IPTC Core schema which is built from properties of the IPTC “Information Interchange Model” (IIM) standard [IPTC IIM].

  • The IPTC Extension schema extends and complements the IPTC Core schema by an additional set of more granular properties and further specialised rights-related properties from the PLUS metadata schema [PLUS].

This allows users to decide whether …​

  • …​ to use only the IPTC Core schema that has a higher backward compatibility, but less refined metadata

  • …​ or to use the IPTC Core and the IPTC Extension schemas with refined and specialised metadata, but restricted backward compatibility.

This document provides the latest specifications for both schemas.

2. Technical Metadata

Digital cameras capture metadata at the time the image is taken reflecting technical characteristics. Such metadata may include, but is not limited to, generic camera metadata, camera manufacturer-specific metadata, ICC profiles and positioning data. Standards for these metadata are not subject to IPTC Standards, but are under the control of the camera manufacturers, their associations (such as CIPA) and others. Because the IPTC acknowledges these technical metadata standards of other bodies and does not wish to duplicate existing metadata properties, the IPTC Photo Metadata specification does not include any technical metadata.

3. History

In 1990, the IPTC developed its “Information Interchange Model” (IIM) metadata property standard for exchanging news that was, by design, media-type agnostic and thus encouraged users to apply it to photos. A few years later, the software company Adobe Systems, Inc., adopted a subset of IIM properties for its imaging software Photoshop and developed a metadata storage technology named “Image Resource Block” to embed the metadata properties in a header section of the image files. From that moment on, millions of photographs were annotated using IIM metadata.

In September 2001, Adobe introduced its new technical metadata framework “Extensible Metadata Platform (XMP)” [Adobe-XMP] that may make the “Image Resource Blocks” sooner or later obsolete. The XML-based XMP technology is much more flexible and can deal better with globalisation requirements. In 2012 the core definition of the data model and the XML syntax were defined by ISO as standard 16684-1 [ISO-XMP].

In 2004, IPTC and Adobe jointly developed the “IPTC Core Schema for XMP” which is actually a redefinition of the IIM properties in the new XMP environment; only a few properties were added.

In 2007, the IPTC collected requirements from different sectors of the professional photography business – with a focus on news photography and stock photography – and published these requirements in its Photo Metadata White Paper 2007 [PhMdWP2007]. After receiving wide assent to this paper, the IPTC developed specifications for the “IPTC Extension Schema” and slightly revised the IPTC Core specifications. Both specifications were released in a single document named “IPTC Photo Metadata Standard” and have been slightly updated in 2009, 2014 and 2016.

4. Photo Metadata specification notation

4.1. The specification template

This specification document provides for each photo metadata property a full specification including:

The specification of a Photo Metadata property is shown in a generic table form using the following template.

Specification Table Template
Row header What is specified by this row

Name

The reference name of the property used by this specification. This name shall never be translated.

Definition

A photo-specific definition of the semantics of this property, may be translated for localization purposes.

Help Text

A help text for this property which may be displayed by a generic help system of the user interface, and should be translated for localization purposes.

User Note(s)

Any notes that apply to the end user of this property, should be translated for localization purposes.

Implementation Note(s)

Notes targeting parties implementing this property by any specified technology.

Label

Text appearing next to the entry field in the user interface, that should be translated for localization purposes.

Basic Specs

A recommended basic data type. Used values: Text, Number, …​ Structure. Cardinality: how often this property may appear in a set of Photo Metadata about an image. 1 = is mandatory, 0..1 = one occurrence is optional, 1..unbounded = one occurrence is mandatory, multiple occurrences are optional

Required CV

The identifier of a controlled vocabulary that must be used with this property.

History Note(s)

A note in which version of the specification or, if there was an error in the specification document, in which revision of this specification document a property was changed and how.

XMP Specs

The specification of the property by XMP: The namespace alias and the property identifyer separated by a colon, see section “XMP Namespaces and Identifiers” of IPTC Core and IPTC Extension. Pluse the value type as as defined by the XMP specification’s XMP Category and how the value of the property is generated - external, internal - as defined by XMP in []-brackets.

XMP Implementation note(s)

Any note regarding the XMP-specific implementation.

IIM Specs

The specification of the property by IIM: The numeric values of the IIM Dataset and of the property identifier, separated by a colon plus the IIM name of the datataset.

JSON Specs

The specification of the property for JSON:The name of the JSON property plus the data type in []-brackets.

4.2. Generic Specification Notes

4.2.1. The terms Metadata Property and Metadata Structure

The term Metadata Property is used for data about the image content. A metadata property can be made to hold only a single kind of value, or a structure of differrent values, for which the term Metadata Structure is used.

Examples:
  • The metadata property Description is made for only one kind of value, a text string, but may provide this value in different languages. It is important to understand that language translations are NOT a metadata structure.

  • The property Artwork or Object in the Image provides a structure of many sub-fields, and is not designed for only a single value. For a property using a structure, the string “structure” is used in the “Basic data type” cell of its specification table. In this case, check the XMP Value Type cell of the table and refer to the corresponding structure identified in it. For all structures specified by the IPTC this document includes the specification tables for all members of a structure. For all structures specified by another standardisation body, in particular by PLUS, the specifications of the structure can only be found in the specification documents (website, PDF document …​) of this body.

4.2.2. (legacy) appended to a property name

This suffix is used if the IPTC Extension provides a better solution to annotate the information about an image than the IPTC Core does. In this case, the IPTC recommends to phase out the use of the (legacy)-marked property and to move towards using the IPTC Extension. See the notes on this matter in the particular specification table.

4.2.3. (DEPRECATED) appended to a property name

This suffix is used for properties which should not be used any longer. A reason for this is given in the spec table of the property and may include a recommendation to use a different property.

4.2.4. Saving metadata values to files

The values of properties may be saved by both the IIM format and the XMP format in a single image file. A guideline on how to synchronise values existing in parallel is available from the Metadata Working Group [MetadataWG]

IPTC Core schema 1.2 specifications

The IPTC Core schema defines the semantics of a set of metadata properties and their technical expressions by the IIM and the XMP format.

5. XMP Namespaces and Identifiers

The technical XMP format of IPTC Core schema uses different namespaces for different properties.

The namespace URI for some IPTC Core schema properties is: http://iptc.org/std/Iptc4xmpCore/1.0/xmlns/

The preferred namespace-prefix this IPTC Core namespace is: Iptc4xmpCore
The use of this namespace-prefix is not mandatory, but highly recommended for interoperability support.

Other namespaces used for IPTC Core schema properties are:

Name URI Recommended/used Prefix

Dublin Core

http://purl.org/dc/elements/1.1/

dc

Photoshop

http://ns.adobe.com/photoshop/1.0/

photoshop

User interfaces (like the custom panels in Adobe CS products) showing “IPTC Core” properties should refer to this schema as an “IPTC Core” or “IPTC” panel.

8. Non-normative Information

8.1. “Deprecated” IIM metadata elements

Not all of the IIM datasets adopted by Adobe to be used for the Photoshop File Info have been adopted for the IPTC Core schema. In terms of mapping and transferring metadata from the legacy IIM-based headers, these datasets must to be considered as deprecated:

  • Urgency: As this metadata element pertains to distribution management, it was not adopted. However, this data is still synchronised with the XMP property “photoshop:Urgency”, and hence, available for future use, but outside the IPTC Core.

  • Category: As this metadata element was earmarked as deprecated already for IIM 4.1, it was not adopted. However, this data is still synchronised with the XMP property “photoshop:Category”, and hence available for future use – but outside the IPTC Core. For migrating from Category codes to Subject Codes please read the Guideline for mapping Category Codes to Subject NewsCodes section below.

  • Supplemental Categories: As this metadata element was earmarked as deprecated already for IIM 4.1, it was not adopted. However, this data is still synchronised with the XMP property “photoshop:SupplementalCategories”, and hence available for future use – but outside the IPTC Core.

8.2. Synchronising IIM elements with existing XMP properties

This table shows how legacy metadata elements from the “IPTC header” – which were taken from the IPTC Information Interchange Model IIM are synchronised by Adobe Photoshop CS with XMP properties.

8.3. Guideline for mapping Category Codes to Subject NewsCodes

Early versions of IIM included the Datasets 2:15 “Category” and 2:20 “Supplemental Category”. But these two fields were replaced in IIM version 4 (released in 1999) by the Dataset 2:12 “Subject Reference” which must be populated by values from the Subject NewsCodes controlled vocabulary. In version 4 of the IIM specification document the Datasets Category and Supplemental Category were indicated as “deprecated” which meant that after the time of this release these two Datasets should not be populated with values any longer. To support the move from the three letter codes used with the Category Dataset to the Subject NewsCodes this table provides a reference for mapping.

IPTC Extension schema 1.4 specifications

The IPTC Extension schema defines the semantics of a set of metadata properties and their technical expressions by the XMP format.

9. XMP Namespaces and Identifiers

The technical XMP format of the IPTC Extension schema uses different namespaces for different properties.

The namespace URI for some IPTC Extension schema properties is: http://iptc.org/std/Iptc4xmpExt/2008-02-29/

The preferred namespace-prefix this IPTC Extension namespace is: Iptc4xmpExt
The use of this namespace-prefix is not mandatory but highly recommended for interoperability support.

Other namespaces used for IPTC Extension schema properties are:

Name URI Recommended Prefix

PLUS

http://ns.useplus.org/ldf/xmp/1.0/

Row header Specification

Name

Digital Image GUID

Definition

Globally unique identifier for this digital image. It is created and applied by the creator of the digital image at the time of its creation . This value shall not be changed after that time.

Help Text

If an ID already exists, don’t change - otherwise enter a globally unique identifier for this digital image

User Note(s)

The identifier will probably be generated by the technical means of an imaging device or software and should be applied to the digital image file as early as possible in its life cycle. This identifier does not identify any pictured content, particularly in case of a scan of non-digital images, only this digital representation.

Implementation Note(s)

Any algorithm to create this identifier has to comply with the technical requirements to create a globally unique id. Any device creating digital images - e.g. still image cameras, video cameras, scanners - should create such an identifer right at the time of the creation of the digital data and add the id to the set of metadata without compromising performance. It is recommended that this image identifier allows identifying the device by which the image data and the GUID were created. IPTC’s basic requirements for unique ids are: * It must be globally unique. Algorithms for this purpose exist. * It should identify the camera body. * It should identify each individual photo from this camera body. * It should identify the date and time of the creation of the picture. * It should be secured against tampering. This field should be implemented in a way to prove it has not been changed since its value has been applied. If the identifier has been created by the imaging device its type and brand can be found in the Exif/technical metadata.
