The TDM opt-out protocol matters only if your publishing workflow separates discoverability from permission
As of Friday, September 4, 2026, FEP is urging publishers to use the machine-readable TDM opt-out protocol developed with AIE and EDRLab. For authors, translators, and rights teams, the practical question is not whether content is visible online. It is whether your web pages, EPUBs, and PDFs clearly reserve mining rights and point counterparties toward a licensing path.
