1 Based on material developed in ATHENA (IST-507849), INTEROP (IST-508011) and MODELWARE (IST-511731) 6-1b. Atlas Transformation Language (ATL) with RSM Tutorial,

2 2 Based on material developed in ATHENA (IST-507849), INTEROP (IST-508011) and MODELWARE (IST-511731) Outline Atlas Transformation Language (ATL) tutorial with RSM example –Installation –Book2Publish example –RSM References

3 3 Based on material developed in ATHENA (IST-507849), INTEROP (IST-508011) and MODELWARE (IST-511731) ATL (1/2) ATL: Atlas Transformation Language Developed by: –LINA (Laboratoire D’Informatique De Nantes Atlantique) –Université de Nantes Faculté des Sciences et Techniques –Building IRIN –2, rue de la Houssinière, BP 92208 –44322 Nantes cedex 3, France Proposal to the OMG MOF/QVT RFP. Model transformation language –Hybrid Declarative => transformations based on simple mappings Imperative => for complex mappings –Based on OCL Documentation –http://www.eclipse.org/gmt/atl/doc/http://www.eclipse.org/gmt/atl/doc/

4 4 Based on material developed in ATHENA (IST-507849), INTEROP (IST-508011) and MODELWARE (IST-511731) ATL (2/2) An ATL transformation program is composed of rules that define how –source model elements are matched and navigated –to create and initialize the elements of the target models The ATL programs for model to model transformation are called modules. Composed of –Header transformation name variables of source and target models –Import libraries to be imported –Helpers define (global) variables and functions. –Rules describe the transformation from a source model to a target model

5 5 Based on material developed in ATHENA (IST-507849), INTEROP (IST-508011) and MODELWARE (IST-511731) Warning To navigate from an element to its attribute, –write the name of the element, then “.” and the name of the attribute; If an identifier (variable name, metamodel name, model element name, etc.) is in conflict with a keyword, –it has to be marked with apostrophes; The ATL parser is case sensitive. This concerns –the file names –the source code itself.
