The IPTC NewsML-G2 Working Group and the News Architecture Working Group are happy to announce the release of the latest version of our flagship XML-based news syndication standard: NewsML-G2 v2.33.
Changes in the latest version are small but significant. We have added support for the Digital Source Type property which is already being used in IPTC’s sister standards IPTC Photo Metadata Standard and IPTC Video Metadata Hub and ninjs. This property can be used to declare when content has been created or modified by software, including by Generative AI engines.
Examples of other possible values for the digital source type property using the recommended IPTC Digital Source Type NewsCodes vocabulary are:
| ID (in QCode format) | Name | Example |
| digsrctype:digitalCapture | Original digital capture sampled from real life:
The digital media is captured from a real-life source using a digital camera or digital recording device |
Digital video taken using a digital film, video or smartphone camera |
| digsrctype:negativeFilm | Digitised from a negative on film:
The digital image was digitised from a negative on film on any other transparent medium |
Digital photo scanned from a photographic negative |
| digsrctype:minorHumanEdits | Original media with minor human edits:
Minor augmentation or correction by a human, such as a digitally-retouched photo used in a magazine |
Original audio with minor edits (e.g. to eliminate breaks) |
| digsrctype:algorithmicallyEnhanced | Algorithmic enhancement: Minor augmentation or correction by algorithm |
A photo that has been digitally enhanced using a mechanism such as Google Photos’ “denoise” feature |
| digsrctype:dataDrivenMedia | Data-driven media: Digital media representation of data via human programming or creativity |
Textual weather report generated by code using readings from weather detection instruments |
| digsrctype:trainedAlgorithmicMedia | Trained algorithmic media: Digital media created algorithmically using a model derived from sampled content |
A “deepfake” video using a combination of a real actor and a trained model
|
The above list is a subset of the full list of recommended values. See the full IPTC Digital Source Type NewsCodes vocabulary for the complete list.
Guidance on using Digital Source Type
The IPTC Photo Metadata User Guide contains a section on Guidance for using Digital Source Type including examples for various types of media, including images, video, audio and text. The examples referenced in this guide can also apply to NewsML-G2 content.
Where Digital Source Type can be used in NewsML-G2 documents
The new <digitalSourceType> property can be added to the contentMeta section of any G2 NewsItem, PackageItem, KnowledgeItem, ConceptItem or PlanningItem to describe the digital source type of an item in its entirety.
It can also be used in the partMeta section of any G2 NewsItem, PackageItem or KnowledgeItem to describe the digital source type of a part of the item. In this way, content such as a video that includes some captured shots and AI-generated shots can be fully described using NewsML-G2.
