Hello,

At the moment I have some sort of Model-driven Architecture, that works as follows:

I have a textual model (created with Xtext). When parsed as an in-memory model, it is transformed to another, more detailed model using ATL. Then, it is transformed to text using XPand. (Thus, XText is only used to parse the model, and the code generation phase is left to other tools).

I quite love this approach, but seeing the XText/XTend 2.0 webinar a different approach is shown to generate code from a model.

What would be the advantages of XText / Xtend over using my MDA approach?

Especially, why is the notion of meta models completely gone in Xtend? Isn't it a great concept that provides structure and clarity?

I would love to hear different opinions about these approaches.

My company: Sytematic, building business software from models.
