This is a web-based tool for supporting the derivation of architectural models (namely, statecharts) from goal models. A video demonstration is available at https://www.youtube.com/watch?v=vl4MdkGkzdQ (additional features were released after the recording of this video).
A live version of the tool is available here: https://gatoalpha-1049.appspot.com/

- Creation of Design Goal Models (DGM) with Awareness Requirements (indicators) and parameters
- Export a metamodel to be used with Zanshin
- Annotation of DGMs with delegation and flow expressions
- Save goal model as a JSON, SVG or PNG file
- Derive statechart from DGMs, based on the flow expressions
- Save the derived statechart as SVG or PNG
This tool is discontinued. No new functionalities will be added, but bugs reported on this repository may be fixed. Pull requests are welcome.
Further info on the tool's requirements and architecture are provided in Chapter 5 of the thesis and in related papers.
The client is developed with plain HTML5, CSS and JavaScript. No building process is required. The only feature that requires the backend is the statechart derivation, thus the goal modelling features can be used offline.
- JointJS and Raphael - provides the core modeling functionalities
- Bootstrap 2.3.2 - professional-looking style and components
- jQuery - facilitates DOM manipulation and cross-browser support
- X-editable - enables inline editing of DOM elements
- Mermaid - draws the statechart diagram
These libraries can be found in the src/main/webapp/lib folder.
The generation of the transitions and super-states (composite states) of the statechart is handled by a Java web service. The input flow expression is tokenized and parsed by code generated through SableCC with the grammar defined in exp.grammar. The resulting tree is evaluated and returned as a JSON object.
- GSON - to convert the resulting objecto to JSON
- JSTL - JavaServer Pages Standard Tag Library
These libraries can be found in the src/main/webapp/WEB-INF/lib folder.
Any Java EE server should be able to host this tool. It is currently deployed at Google App Engine, instructions for which can be found here. See also instructions for their Eclipse plugin.
When hosting this tool you'll need to change the endpoint URL in the getStatechart function within derivation.js.
The tool was developed by João Pimentel.
