we are currently looking at adding REST support to the RemoteAdmin plugin (other stuff to follow) — the idea being that we can get information about (as well as change state of) a running OpenSim instance not only via XmlRpc but also via REST.

looking at the way we currently deal with serialization we either

• use LLSD where mandated by secondlife (e.g., CAPS)
• use .NET’s System.Xml.XmlSerializer
• use XmlRpc serialization (which goes back to System.Xml)

LLSD is being used by linden lab’s and is proposed by LL/SLAWG as the serialization protocol of choice (IIUC). in my opinion it suffers from being a bit verbose and not really easy to parse.

XmlSerializer is “built in”. on the other hand it’s wordy and more complex to parse; also, it doesn’t distinguish between the number 4711 and the string “4711” — you have to know that a certain tag contains a string (or a number).

another alternative that has been suggested is JSON. JSON is lean, and easy to use from AJAX apps as well as python scripts (and the likes). it requires an additional DLL. it does however distinguish between strings and numbers. using a library like jsonexserializer — BSD license — makes it easy to use from C#.

personally, i’ve started to like JSON because it’s lean and easy to use — but i’d like to hear from you guys what you think about this. so, give it a vote!
