This project is an unofficial effort to document the protocol used by OpenSimulator/SecondLife virtual world.
Please be aware that these findings reflect my personal understanding of the protocol and there are likely going to be multiple mistakes.
Also consider this a steady work in progress. If you are interested in contributing let me know through email or the issue tracker and I can help you get started.
Originally I started this project to inject some documentation into generated code in my Rust implementation of the full networking stack opensim-networking.
The biggest previous effort on providing an open source implementation (in C#) and some documentation of the protocol, has been made by the libOpenMetaverse project. Their implementation is currently used by OpenSimulator, and can be used as a de-facto reference for new implementations.
Even though the protocol has been developed at Linden Research we refer to it as the opensim-protocol because this project's goals is to track the opensim flavor of the project should there be incompatible changes in the future.
Please be aware that any documents provided in the scope of this project reflect a personal understanding of the protocol, it is possible and likely that the real protocol used by software in the wild diverges from these findings.
