Text and Data Mining (TDM) is used by both private and public entities to analyze large volumes of data, including copyrighted content like ebooks. Because these techniques are subject to legal conditions, mass processing requires a way to quickly identify works where TDM is restricted or prohibited by rights holders.

Objectives

• Inform indexing systems whether Text and Data Mining (TDM) is authorized or prohibited for the ebook’s content.

Implementation

• For EPUB 3 files where TDM rights are reserved, add the tdm:reservation metadata to the OPF file. If a license is available online, provide its URL using the tdm:policy metadata.
• Follow the TDM Reservation Protocol (TDMRep) recommendation for implementation examples involving EPUB 2 and PDF files.
• Include a written statement regarding the publisher’s TDM policy on the copyright page to ensure the policy is clear to both human readers and automated systems.

Control

• Check for the tdm:reservation and tdm:policy metadata and ensure they match the statements provided on the copyright page.
