Trinity Specification Language

The Trinity Specification Language (TSL) is a declarative language that is designed to provide system flexibility. Instead of using a fixed data schema and fixed computation paradigms, GE allows users to freely define data schemata and extend the system capability by performing user-defined server-side computation.

The browser does not support SVG.

TSL glues the following three things together: data modeling, message passing protocol modeling, and data interchange format specification. From the perspective of data modeling, TSL functions like IDL in CORBA; From the perspective of message passing protocol modeling, TSL resembles the Slice specification language of ICE (Internet Communications Engine); From the perspective of the data interchange format specification, TSL works like protocol buffers or MessagePack, allowing users to exchange data without serialization and deserialization via an efficient way of encoding structured data.

GE compiles a TSL script into a .Net assembly. The generated assembly is a GE extension module which contains a set of extension methods to the GE system.
