The EGL compiler is closed in the same sense as any compiler as it is dealing with a predefined set of concepts.

The EGL generator reads this model and transforms it into runtime source code. If validation is successful, the intermediate representation of the source code will be serialized. The EGL compiler is responsible for validating and binding the basic core language as well as enforcing the constraints defined by various stereotypes. Therefore, in EGL these two steps have been explicitly separated into a compile step (which converts EGL source code to a serializable intermediate model) and a generation step (which takes the intermediate model and generates some other type of source code). However, in EGL the set of concepts to be compiled and transformed is extensible. Typically the set of constructs and concepts a compiler must deal with is a closed set so both steps can be handled by a single processor called the compiler. Generation from that intermediate model to the appropriate byte code (object code) or platform-specific instructions.Conversion of the source code into some intermediate model representation.The compilation process usually has at least two major phases:

With most programming languages, source code is either compiled into a standard set of byte codes readable by a VM (Virtual Machine) or the code is compiled into the actual machine instructions for a specific platform. Stereotypes in EGL are essentially the same idea and are used to extend the basic EGL core language concepts. Stereotypes in UML are used as a lightweight mechanism to extend the standard modeling concepts. Constraints can be defined by stereotype definitions such that elements stereotyped by the given stereotype must adhere to the defined constraints of that stereotype. In UML, stereotypes are used to tag UML elements with metadata (in this case, metadata refers to information about the UML element, for example, information about a UML element called a 'class'). However, it borrows a concept from UML (Universal Modeling Language) that is not typically found in statically typed programming language – the concept of Stereotype. The language borrows concepts familiar to anyone using statically typed languages like Java, COBOL, C, etc.
