This document describes the Linden Lab Structured Data (LLSD) abstract type system, interface description and serialization formats. LLSD is a language-neutral facility for maintaining and transporting structured data. It provides dynamic data features for loosely-coupled collections of software components, even in statically-typed languages. LLSD includes an abstract type system, an interface description language (LLIDL) and three canonical serialization schemes (XML, JSON and Binary).
