ALMOsT-trace: A web based embeddable tracing tool for ALMOsT.js

Model Driven Development (MDD) requires model-to-model and/or model-to-text transformations to produce application code from high level descriptions. Debugging and evaluating such transformations is in itself a complex task; complexity which can be mitigated through the usage of advanced developer tools. We demonstrate ALMOsT-Trace, a plug-in for ALMOsT.js, which allows developers to debug and analyze their model transformations from within their applications. In the demo, attendees will be able to experiment with ALMOsT-Trace by evaluating it in IFMLEdit.org, an online tool for the rapid prototyping of web and mobile applications, and by means of examples that can be customized by the attendees themself.
