Compatibility

TAP coexists with Schema.org, C2PA, IPTC DST, Dublin Core, SPDX, and W3C PROV-O. The Web profile's JSON-LD IS Schema.org. TAP adds the model/human/role/confidence layer these standards lack. C2PA proves file integrity; TAP declares who did what.

EU AI Act (Article 50, applicable from August 2, 2026) mandates disclosure of AI-generated content but does not prescribe a metadata format. TAP provides a voluntary, machine-readable format that satisfies the Act's disclosure requirements. TAP's Display profile values (human, ai-involved, ai-generated, ai-modified) map directly to the categories the regulation distinguishes. TAP alone does not constitute legal compliance - implementors must verify jurisdiction-specific obligations.

TAP is voluntary self-declaration, not cryptographic proof. It requires no keys, no hardware, no registry. A valid TAP declaration is a line of text.
