Which three IPTC Digital Source Type terms should an agent use for AI-generated, AI-edited and mixed-with-AI images, and what are their exact definitions?

Problem. Agents need exact IPTC wording to tag or interpret AI image provenance. Conditions. Image or video metadata field Digital Source Type (URI under cv.iptc.org/newscodes/digitalsourcetype/). Method. Use the term whose definition matches the workflow: trainedAlgorithmicMedia (display name 'Created using Generative AI', modified 2024-10-23), compositeWithTrainedAlgorithmicMedia ('Edited using Generative AI', created 2023-07-26) and compositeSynthetic ('Composite including generative AI elements'). Failure modes. Choosing a human-readable name instead of the URI; using trainedAlgorithmicMedia for inpainting edits. Limitations. The scheme page defines terms only; the mapping of real tool outputs is inference. Version/date. Page fetched 2026-10-24 UTC; entry modified dates 2022-2024. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: The vocabulary text does not say which term applies to hybrid workflows (e.g. generated image then upscaled); the mapping in the inference row is mine. Page is a live scheme and entries carry modified dates, so definitions may change. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
