This document summarizes key points about intellectual property rights (IPR) considerations for a digitalization partnership between three Belgian institutions - NBGB, RBINS, and RMCA - called Be-TAF. It discusses IPR best practices for openly licensing content, managing copyright risks for different date ranges of publications, and models for rights agreements. It also examines some controversial edge cases and considers scientists' views that publicly funded research results should be widely disseminated with proper citation. The conclusion is that while efforts will be made to avoid infringing content, some risk cannot be eliminated and a notice-and-takedown policy should be implemented to manage any issues.
