Script protocols and known chat channels

Some times, scripts in Second Life send messages to one another to exchange information or coordinate behavior. The rules for that conversation are a protocol. Being able to say "/1show" or "/1hug lee" are examples.

Such protocols use a common chat channel. The examples above use channel 1. They could just as easily have used any other number, but a user (and other objects) have to have some way to find the correct number.

Some protocols, such as combat systems, are quite complicated and could be better documented. This page can be used to help prevent conflicts and allow multiple programmers to coordinate the protocol definitions.

Protocols can also be note card systems and systems that use object names.

Protocol list

Add a protocol here if it is widely used, or might be sometime in the future.

A protocol in this list should also have its own pages where the protocol is defined in some detail.

OpenMAIP Ganymede Ceriaptrix Note: Specification is presently incomplete. Ganymedia OpenMAIP (Metaverse Application Internetworking Protocol) provides a TCP/IP-like routing and service-oriented message exchange protocol across multiple transport methods (including cross-simulator and cross-grid); allowing scripts to advertise their available functions, and relevant commands, to external and/or third-party scripts and viewers. Controlled access to closed functions is provided via RC4 challenge-response authentication. OpenMAIP also provides an optional RC4 cryptography layer, further extensible to public-private key DHSS.

Teacup (LSL HTTP Server) Void Singer An LSL Web Page Server for serving HTML content solely from within SL using shared media (Spec, protocols, linked examples)
Open Radio Communication Kyrah Abattoir A barebone "binary like" radio protocol with interferences and crosstalk.

Known chat channels

This list is intended to reduce the number of scripts using the same chat channel number. Please try and keep them in sequence. Note that the absence of a channel reservation in this list does not mean that channel will never be used - some scripts choose channels randomly from a very, very large range, sometimes a range of all possible channels. Always design your communication protocols such that invalid/interfering messages are disposed of.
