A public-domain authorship vocabulary for content. Three marks. Human-readable and machine-readable.
What is Made Mark?
Made Mark is an open specification for content authorship disclosure. It answers the question no existing standard addresses: how was this content made? A CC license tells you what you can do with content. CC Signals tells you whether it can train AI. Made Mark tells you who — or what — made it.
It is built on the same three-layer architecture as Creative Commons licenses — a visual mark, a plain-language label, and a machine-readable expression. Made Mark is designed to travel inside C2PA manifests as a human-readable semantic layer, giving authorship disclosure both cryptographic provenance and plain-language meaning. Standalone use without C2PA is also supported.
The Made Mark specification is public domain. Use it, implement it, build on it.
The three marks
Three marks of authorship. Not a ranking — a vocabulary. Each describes a different reality about how content came to exist.
Conceived and produced by people.
mademark.org/marks/human-madeHuman creative direction, AI production.
mademark.org/marks/human-designed-ai-madeConceived and produced primarily by AI.
mademark.org/marks/ai-madeThe label has a full form and a short form. Full: MM · Human Designed AI Made · Claude Sonnet 4.6 · Anthropic · CC BY 4.0. Short: MM · Human Designed AI Made. The mark is the irreducible core — all other fields are optional. The full form is designed to travel inside C2PA manifests, so authorship disclosure moves with the content rather than staying behind on a webpage.
Use and licensing
Made Mark is built on a split model — the same approach Creative Commons uses for its own work. The openness is in the specification. The protection is in the signal.
CC0, public domain. The vocabulary, label syntax, URI structure, and documentation are dedicated to the public domain. No rights reserved. Implement Made Mark without asking.
CC BY-ND 4.0. Free to use unmodified to identify Made Mark authorship on content. Do not modify, recolor, or repurpose outside this context. Credit: Made Mark, mademark.org.
