The jMML library is an implementation of most of the language features of the Multiscale Modeling Language (MML). It can read the XML format of MML (xMML) and generate

• a graphical coupling topology
• a graphical task graph
• a graphical domain subdivision
• a MUSCLE configuration file
• a MUSCLE skeleton configuration

The library is divided in three parts: jMML-util which contains all utility classes like SI unit handling and data types. Then jMML-specification uses JAXB to convert a xMML file into Java classes. This conversion is automatically done based on the xMML XML Schema. Finally, jMML-api does content generation. Although only 5 files can be generated, from the API any number of descriptions of for instance a task graph or a coupling topology can be generated.

Dependencies are Java, Maven 3 and Graphviz.

Compile the code with

mvn install

and run it with

bin/jmml path/to/xmml_file.xml -g path/to/task_graph_file.pdf

Other options are shown when running bin/jmml.

The xMML should be validated with the xMML validate tool.

The code has three modules: jmml-api, jmml-specification and jmml-util. The jmml-api module contains the actual algorithms, jmml-specification contains the XML bindings to xMML and jmml-util contains unit and formula handling.
