Anyone know this language?
This technology is called Agile Platform complete solution to deliver custom enterprise web apps with high productivity.
What do you think of it?
It appears to be a UML-based model-driven architecture (MDA) tool. It is not a language (although UML may be considered as such). It will take the model, and turn it into code (.net or java in this case). For complex systems, such tools (I use something similar called Enterprise Architect by Sparx Systems in Australia, but IBM's Rational tools are popular, if expensive) are very useful, and definitely increase productivity, if only by letting you visualize the relationships between entities in the system (class models and use-cases), and their behaviors (state machines, sequence and activity diagrams, etc).
