1. In data management context: The generation of a copy of a data object that is referenced by the same name, but with a different replica number. When changes are made to the data object, the replica can be updated to track the changes. AKA, duplication. As part of replication data may be given a PID for a repository. Enhanced metadata may be stored in a repository as part of replication. A PID should allow replicated from different communities to be identified as such. Related term replica number, PID, repository. 2. In the context of research: The evaluation of scientific claims by independent investigators using independent methods, data, equipment, and protocols (Peng, 2011). 3.
