== PetriPad == PetriPad is a real-time collaboration extension for Renew. It enables simultaneous editing of the same documents from different editor instances over a network. PetriPad uses a lightweight plugin for Renew that connects with a collaboration server that handles communication and session management. The server is implemented as a multi-agent system built upon the Mulan framework and the PAOSE approach. Communication between Renew clients and the server is handled by the WebSocket protocol.
