#Operational Transformation Engine API
##About
This project contains the JavaScript source for the operational transformation (OT) engine.
The OT engine is exposed as a library for application programmers who wish to build collaborative groupware applications.
##Usage
Application programmers wishing to use the OT API can checkout this project as a git repository (or submodule into an already existing git repository), or download the code as a tarball and extract into their project.
Each participating peer has its own instance of an operation engine. Each peer maintains its own local copy of the collaborative data.
The engine is exposed through the use of two primary mechanisms: applying local/remote operations and sending/retrieving engine internal data structures. Each API call returns a data structure (eg. JSON) that should be forwarded to other remote peers exactly as is. Remote peers then send this data structure through another API call, which returns an operation that should be applied to a local copy of the data.
##Requirements
This OT API library does not provide a mechanism to communicate directly with remote peers. Thus, the application programmer is responsible for the communication mechanism (eg. hosting a central server to ferry data between clients).
##OpenCoweb This library was initially started as a part of the OpenCoweb project. OpenCoweb provides a Java-based server and uses cometd techniques to allow remote peer communication and exchange of remote events. OpenCoweb incorporates the OT API to allow developers to write collaborative groupware web-based applications.
