Kermeta is workbench and an action language dedicated to metamodel engineering.
The action language is a Domain Specific Language (DLS) that fills the gap let by MOF which defines only the structure of meta-models, by adding a way to specify static semantic (similar to OCL) and dynamic semantic (using operational semantic in the operation of the metamodel). Kermeta uses the object-oriented paradigm like Java or Eiffel.
The workbench allows to mashup various languages that, like Kermeta, works at the MOF level. (For example, OCL, QVT, UML profiles, ...). This means that, at design time, a user may decide to use a language adapted for a given task. The workbench will help to combine the various inputs in an efficient runtime.
This document gives beginners an introduction to the Kermeta action language and to the workbench, then it offers a reference of all the aspects of the language, including the textual syntax, the metamodeling features and some more advanced features. Two other chapters present the Kermeta Metamodel and the Kermeta framework .

Kermeta has undergone a major refactorings between its version 1.x and 2.x. They apply both to the internal tooling and also on the language itself. In order to help identify the major changes between these versions, you can look for notes like the following :
