With its updated site and recent blog post from its CEO Stefano Butti, WebRatio is allowing its customers to move at full throttle towards the new OMG standard IFML, the Interaction Flow Modeling Language.
In particular, WebRatio is now granting the availability of both an opensource IFML editor with proof of concept implementation of integrated fUML and Alf runtime support and of the industrial-strength implementation supporting end-to-end development, from model definition to code generation and deployment (the WebRatio application platform). These are great facilities for future IFML developers and contributors.
