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 specification is split into two different schemas:

(A schema is a set of metadata properties.)

  • The IPTC Core schema was built initially from properties of the IPTC “Information Interchange Model” (IIM) standard [IPTC-IIM] (in use since 1995). A few additional properties related to existing IPTC Core properties have been added. This schema is backward compatible with properties going back to the 1990’s.

  • 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]. It started in 2008.

This document provides the latest specifications for both schemas.

2. Generic Notes

The notes below apply to the specification as a whole.

Be aware that values assigned to rights-related metadata properties - such as properties about licensing – of an image may be affected …

  • … by laws and other regulations of the region in which the image is used.

  • … by contracts applying to the image.

2.2. 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. 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” in 2008 and have been updated or extended in 2009, 2014, 2016, 2017, 2019, 2021, 2022 and 2023.

4. What’s New in This Version

In general: search this document for the term 2023.2, this will show you in the sections of the IPTC Core and the IPTC Extension schemas all added or changed metadata properties. The term can be found in the History Notes row.

4.1. Quick Overview

  • Generic Notes: this section was created and includes new notes about Rights-Related Metadata and the existing notes about Technical Metadata

  • All specification tables: a new row at the bottom shows corresponding ExifTool tags as help for developers

  • IPTC Extension schema

    • New properties Data Mining and Other Constraints

5. Photo Metadata specification notation

This document provides a human readable specification of the IPTC Photo Metadata Standard.

5.1. Specification table template

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

  • A specification of its name, semantics, requirements and text to be used with the user interface of a software implementing this property.

  • A specific technical implementation using Adobe’s XMP technology Adobe XMP, ISO XMP

  • A specific technical implementation using IPTC’s IIM standard. IPTC IIM

The specification of a Photo Metadata property is shown in a generic table form using the following template.
Some rows may be missing if there is no use for this specification, e.g. structures have no help text or label as they are applied to a property with help text and label.

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. (As structures are used by fields with labels no label is defined for a structure.)

Basic Specs

The specific data type of a property in XMP or JSON is based on a more generic Data type :
Text = sequence of characters, can be used for free text or other purposes
Integer = integer number
Decimal = decimal number
URL = Uniform Resource Locator, in most cases the web address of a resource
URI = Uniform Resource Identifier for identifying a resource, this includes URLs
…​ Structure = a structure of sub-properties
Cardinality: how often this property must or may occur in a set of Photo Metadata about an image or in a structure of a metadata property:
1 = one and only one occurrence is mandatory,
0..1 = one occurrence is optional,
0..unbounded = one and multiple occurrences are optional,
1..unbounded = one occurrence is mandatory, multiple occurrences are optional

CV Note(s)

A note on the use of Controlled Vocabularies with this property. The term "Required" specifies the use of a specific CV as mandatory.

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.
Search for the identifier of a version of the standard - like 2022.1, 2021.1, 2019.1 or 2017.1 - to find all properties added or modified by it.

XMP Specs

The specification of the property for XMP: The namespace alias and the property identifier are separated by a colon, see section “XMP Namespaces and Identifiers” of IPTC Core and IPTC Extension.
Further 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, both in []-brackets.

XMP Implementation Note(s)

Note(s) regarding an XMP-specific implementation. It may include a reference to a generic note on XMP Properties.

IIM Specs

The specification of the property by IIM: The numeric values of the IIM Dataset property identifier, separated by a colon, plus the IIM name of the datataset. If the basic data type of the property is text "max bytes for text" is appended with the maximum count of permitted bytes. Read more about it in this generic IIM Implementation Note

JSON Specs

The specification of the property for JSON: The name of the JSON property plus the data type in []-brackets.
Data type parts are sepearated by /. Part 1: basic type string, number, object; part 2: subtype like uri, url, date-time or for the basic type object the name of the object (= structure); part 3: no value = single occurrence, array = multiple occurrence. Suffix -MANDATORY = occurrence required.

Help: ExifTool tags

ExifTool (see https://exiftool.org) is a widely used software for reading and embedding IPTC photo metadata. To help users this row shows the ExifTool tag of this property for the XMP format and for the IIM format, if one is defined. This row is NOT NORMATIVE. To support all properties of this version of the IPTC standard using ExifTool version 12.67 or higher is required.

5.2. Machine Readable TechReference

This web document is intended for human eyes reading the specification of the standard. But as reading metadata from image files and embedding metadata into image files is done by software IPTC provides a machine-readable version of the specification that can be consumed directly by software tools. It is called the IPTC Photo Metadata TechReference.

The TechReference is a data object containing all the details of the IPTC Photo Metadata technical specifications in the easy-to-use JSON and YAML formats.

The TechReference can be downloaded:

IPTC has published rich documentation about using the TechReference data object on this page.

5.3. Generic Specification Notes

5.3.1. 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 different 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.

5.3.2. (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.

5.3.3. (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.

5.3.4. Saving metadata values to files

The values of properties should be saved to an image file using both the IIM format and the XMP format as defined in the specification tables.
(A guideline on how to synchronise values existing in parallel was available from the Metadata Working Group [MetadataWG] until October 2018 and was widely used.)

IPTC Core schema 1.4 specifications

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

6. XMP Namespaces and Identifiers

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

The namespace IPTC Core covers only a subset of the properties of the IPTC Core schema.

Help Text

User Note(s)

This property should not be confused with the IPTC property Description/Caption, which is the who, what, when, where, why, how of an image. This property can be combined with Alt Text (Accessibility) if and when a brief description is not sufficient to convey the purpose and meaning of an image. It should not repeat the information in the Alt Text (Accessibility) property. It is required for conformance with the W3C Web Content Accessibility Guidelines (WCAG).

Implementation Note(s)

Extended Description (Accessibility) is designed to be used in conjunction with Alt Text (Accessibility) therefore both properties should be available on the editing interface.

9. Non-normative Information

9.1. “Deprecated” IIM metadata properties

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 metadata, these datasets must 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.

9.2. 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.

11.7. Data Mining

Row header Specification

Name

Data Mining

Definition

Data mining prohibition or permission, optionally with constraints.

User Note(s)

Regional laws applying to an asset may prohibit, constrain, or allow data mining for certain purposes (such as search indexing or research), and may overrule the value selected for this property. Similarly, the absence of a prohibition does not indicate that the asset owner grants permission for data mining or any other use of an asset.
The prohibition “Prohibited except for search engine indexing” only permits data mining by search engines available to the public to identify the URL for an asset and its associated data (for the purpose of assisting the public in navigating to the URL for the asset), and prohibits all other uses, such as AI/ML training.
The PLUS Other Constraints property is human readable. The IPTC properties Embedded Encoded Rights Expression and Linked Encoded Rights Expression are machine readable.

Implementation Note(s)

This is a PLUS version 2.0.1 property included in the IPTC Extension schema. The value must be one of the URIs listed in the Controlled Vocabulary section of the PLUS specification.

11.9. Digital Image GUID

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.
IPTC’s basic requirements for unique ids are:
* It must be globally unique. Algorithms for this purpose exist.
* It should be secured against tampering.
These features may be considered:
* It may identify the camera body.
* It may identify each individual photo from this camera body.
* It may identify the date and time of the creation of the picture.

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.

12.7. Region Boundary structure

Row header Specification

Name

Region Boundary structure

Definition

The properties of the Image Region Boundary structure set the boundary of a region inside an image. As option only a single point may be defined to express special characteristics of this point, or a line may be defined to express a divide inside the image.

User Note(s)

Three options for the shape of the boundary are available: the boundary is a rectangle or a circle or a polygon. For each shape a set of properties is required, properties not listed in this set must not be used.

  • Rectangle: the x- and y-axis coordinates of the upper left corner of the rectangle and the width and height of the rectangle relative to this upper left corner.

  • Circle: the x- and y-axis coordinates of the centre of the circle and its radius measured along the x-axis.

  • Polygon: the x- and y-axis coordinates of the vertex/the vertices of the polygon.

The Shape property defines which of the three shapes is defined and an the Measuring Unit property defines the units used for measuring all distances.

The coordinates of points used as reference of a shape of the region boundary and values defining the size of the shape are expressed by scalar values along the x-axis or the y-axis of a rectangular coordinates system. The rules for this system are:

  • Point Zero of the coordinates follows the Image Data Arrangement of the pixels of a digital image as defined by Exif (CIPA DC-008-2019):

    • The top row of the pixels is the first row, the leftmost pixel of a row is the first pixel.

    • The counting of “top row” and “leftmost” applies to pixel data as set when the pixels were (re-)organized by the camera or by software. The orientation (rotation, flipping) of the image defined by a metadata value MUST NOT be applied.

    • Point Zero of the coordinates is the first, leftmost pixel in the top row.

    • The x-axis is from Point Zero along the top row of the image. The range of coordinate values is from 0 to any positive value not exceeding the size of the image.

    • The y-axis is from Point Zero along the first pixels of the rows in the image. The range of coordinate values is from 0 to any positive value not exceeding the size of the image.

  • Coordinates of a point in the image MUST have an x-axis and a y-axis value.

  • Values defining the size of the shape are measured along the x-axis and the y-axis.

  • The unit of a value is defined by the Region Boundary Measuring Unit property, its value MUST be from the enumeration defined for the Boundary Measuring Unit property.

Row header Specification

Name

Boundary Shape

Definition

The shape of the boundary of a region inside an image. The value MUST be taken from the enumeration rectangle, circle, polygon.

User Note(s)

The applicable shapes are:

  • rectangle = a rectangle as shape of the boundary, the shape of a square is included

  • circle = a circle as the shape of the boundary

  • polygon = any shape with edges, except a rectangle, including a single point (using 1 vertex) and a line (using 2 vertices). The edges between a vertex and the next one in the sequence set the shape, the last edge is the one from the last vertex in the sequence to the first vertex in the sequence.

Boundary Measuring Unit

Definition

Unit used for measuring dimensions of the boundary of a region. The value MUST be taken from the enumeration pixel, relative

User Note(s)

The applicable units are:

  • pixel = A pixel of a digital image setting an absolute value

  • relative = Relative part of the size of an image along the x- or the y-axis. The range of the value is from 0 to 1 representing the proportion of the full size of an image along the x-axis or the y-axis.

Implementation Note(s)

If the unit "pixel" is used: in case of rescaling the image the coordinate values and the radius of a circle must be rescaled too.

Generic Implementation Notes

This chapter covers notes regarding the implementation of the IPTC Photo Metadata Standard properties in software.

The notes apply across properties but they are grouped by XMP and IIM. IPTC Standard property specific notes can be found in the specification table of the property.

14. XMP Properties

14.1. Lang Alt value type

Applies to an XMP property if its value type is Lang Alt: This type enables an XMP property to hold the same text in different languages with an identifier of the used language. Any software dealing with this property must abide to the processing rules for the Lang Alt value type as specified by the XMP specifications.

14.2. Date value type

Applies to an XMP property if its value type is date: The XMP specification defines a quite flexible format for this value type, all these sets of year, month, day and time values are supported:

  • YYYY

  • YYYY-MM

  • YYYY-MM-DD

  • YYYY-MM-DDThh:mmTZD

  • YYYY-MM-DDThh:mm:ssTZD

  • YYYY-MM-DDThh:mm:ss.sTZD

IPTC encourages makers of software to adopt a user interface widget for the Date value type properties which allows a user to enter all these variants of date and time.

Note the format of dates and times shown above is based on the ISO 8601 standard for date and time formats [ISO-8601]

15. IIM Properties

15.1. Max bytes for text

The specification tables of the IPTC Photo Metadata properties may include "max bytes for text". Be aware that this number expresses the limited count of bytes which can be used for this IIM property and not the count of characters. If UTF-8 encoding of text is used and if non-ASCII characters appear in the text the UTF-8 encoding uses more than one byte for a single character. If this is the case, fewer characters than the "max bytes of text" can be embedded. Please read the full IPTC IIM specifications.
