We describe a meta tool for specification and generation of multiple view visual tools. The tool permits rapid specification of visual notational elements, the tool information model, visual editors, the relationship between notational and model elements, and behaviour. Tools are generated on the fly and can be used for modelling immediately. Changes to the meta tool specification are immediately reflected in tool instances. 1.

Complex data mapping tasks often arise in software engineering, particularly in code generation and model transformation. We describe Marama Torua, a tool supporting high-level specification and implementation of complex data mappings. Marama Torua is embedded in, and provides model transformation support for, our Eclipse-based Marama domain-specific language meta-tool. Developers can quickly develop stand alone data mappers and model translation and code import-export components for their tools. Complex data schema and mapping relationships are represented in multiple, high-level notational forms and users are provided semiautomated mapping assistance for large models. MaramaTorua is a set of Eclipse plug-ins allowing close integration with other tools such as schema browsers, and with the Marama meta-tool itself. 1.
