TDMRep Protection
About TDMRep Protection
TDMRep (Text and Data Mining Reservation Protocol) protects your PDFs from unauthorized AI scraping:
- Adds W3C-compliant metadata to reserve TDM rights
- Signals to AI crawlers that permission is required
- Links to your licensing policy for legitimate users
- Complies with EU DSM Directive Article 4
How It Works
When you protect a PDF with TDMRep, metadata is embedded that tells AI systems and web crawlers that text and data mining rights are reserved. Legitimate users can follow your policy URL to request permission.
