A Conflict-free Replicated Data Type (CRDT) is a data structure that simplifies distributed data storage systems and multi-user applications. site 
In many systems, copies of some data need to be stored on multiple computers (known as Replicas).

P2P Semantic Web Replication. Except C-Set [1] that is a CRDT (Commutative Replicated Data Types) designed to be integrated within a semantic store in order to provide P2P synchronisation of autonomous semantic store, all previous work on replication in semantic P2P systems such Delta [17], RDFGrowth [18] and RDFPeers [4] are focused on sharing RDF resources. However, C-Set is not suitable for mobile devices since it incurs some overhead and does not consider directly a set as a list (or a sequence).
