REPLIX is a project studying and implementing the next level in grid based safe data replication and syn- chronization. This is important for preserving our peta- bytes of language resources for the future. REPLIX will focus on issues such as data authenticity, data integrity, maintaining access rights and data organization since they are so crucial for proper data management in a distributed environment. Replication in this context means copying data in one direction thus realizing a master-slave relationship, while synchronization is much more challenging in a world where copies of collections are extended and new versions are created at various places. To handle replication and synchronization in a proper model for digital object (DO) identity, REPLIX will make use of information associated with persistent identifiers (PID).
