Visual REST is a graphical modelling language for the design of resource-oriented applications. I developed Visual REST as part of my master’s thesis at the University of Hagen in 2012. It is implemented as an Eclipse-based editor using Graphiti and enables creation of application models. As of today, code generation is not part of the IDE, though.
Visual REST is
available on Bitbucket. available on GitHub It is, however, no longer actively developed. If you are looking for a graphical modelling language for RESTful applications I suggest taking a look at the REST API design tool developer by the people at Visual Paradigm.
Visual REST as a language and thus also our Eclipse-based implementation consists of four types of views on an application model. The resource structure type overview diagram shows the complete resource-oriented application:
The resource type structure diagram shows a more verbose representation of resource types in an application. Visual REST also allows partitioning an application over more than one such diagram.
The resource type states diagram visualizes resource type states and the methods that are supported in each state. It also shows the transitions between states.
Finally, the resource type method behavior diagram models the behaviour of each method.
The following image shows how the different view of the language relate:
The following pages give an overview of the syntax elements available for the different Visual REST views:
The Eclipse Editor
The editor supports developers by prodiving additional features besides editing the language itself. Amongst others, one of these features is the application outline which the following screenshots shows:
Obtaining the Editor
The editor is built from source automatically. The latest stable builds can be obtained from our continuous integration server:
latest stable build (continuous build)
- nightly build (TBD)
- release builds (TBD)
More info can be found on the ContinuousIntegration wiki page.
