In computer programming, a rope, or cord, is a data structure composed of smaller strings that is used to efficiently store and manipulate a very long string. For example, a text editing program may use a rope to represent the text being edited, so that operations such as insertion, deletion, and random access can be done efficiently.[1]

A Conflict-free Replicated Data Type (CRDT) is a data structure that simplifies distributed data storage systems and multi-user applications.
