Opt-out Declaration

Example of a machine-readable declaration by the rightsholder prohibiting use of content for training models and applications of generative AI.

Text and Data Mining (TDM) is permitted for general purpose AI systems that do not generate synthetic audio, image, video, or text content and for scientific research purposes or for temporary acts of reproduction as provided for in Article 5(1) of Directive 2001/29/EC."

Expression of an opt-out declaration

When we speak of a "machine-readable opt-out", we mean an explicit reservation by the rightsholder that reproductions and extractions of lawfully accessible works and other protected subject matter are not permitted for the purposes of TDM for the purpose of training models and applications of generative AI. An opt-out is not possible for use for scientific research purposes.

Opt-out Revocation

Example of a machine-readable statement indicating that the rightsholder has revoked a previously issued opt-out declaration for TDM for AI, thus changed its position on the previous restriction.

Opt-out Revocation

  "iscc": "ISCC:KEC7VSV5QH7FTV7N5YVD5UMF4TUKFFGDGCOI4UDFKE4FNPW6C3L7J2Y",
  "TDMAI": true,
  "TDMAI_summary": "Content may be used for training generative AI.",
  "TDMAI_policy": "A reservation against the automated analysis of the work in order to extract information from it, in particular about patterns, trends and correlations for the purpose of training models and applications of generative AI, is not declared."

Expression of an opt-out revocation

An “opt-out Revocation” indicates that the rightsholder has made a declaration that should be interpreted in a way that no opt-out applies (anymore). While one might argue that such a declaration is redundant because permission is the default assumption, there are scenarios where the rightsholder may have initially expressed a machine-readable reservation but subsequently changed their stance.
