[erlang-questions] ExecutableUML and Erlang

I've also looked at this. My conclusion was that it provides a nice graphical syntax for a particular domain, but has weak abilities to define additional abstractions on top. For example, just as in Erlang messages are delivered asynchronously to recipients. But if you want to define *synchronous* communication with a server on top of that, by including the Pid of the sender in the message and sending a reply back to that Pid, then you have a problem--because Pids are not first class in xtUML and cannot be sent in messages, because message destinations must be statically known and so your server must know all of its possible clients in advance, and because you cannot define new graphical syntax so as to use synchronous message sending with the same convenience as the asynchronous kind.

Not impressed.

  Hi everyone, 

  In echo to the older thread "UML or other modeling tools" (http://erlang.2086793.n4.nabble.com/UML-or-other-modeling-tools-td3205732.html), we happened to find an Ericsson presentation about ExecutableUML (http://www.cse.chalmers.se/edu/year/2010/course/MDSD/Year2010/Lectures/ExecutableUML_for_MDA_EricssonAB.pdf), which apparently was already able to generate Erlang code. 

  This xtUML looks like a very interesting approach; in short we are contemplating to specify some domain-specific models that are involved in a discrete simulation, based on a proper high-level, formal, implementation-agnostic pivot format, targeting a few different simulation engines, one of which expecting models to be written in C++, another one expecting them in Erlang. So it looks like if our pivot format could be a flavour of xtUML (a special, constrained, case thereof). 

  Is there any material (documentation and/or tool) that is publicly available, so that we could test this ExecutableUML-based approach? Any opinion in terms of completeness, applicability or maturity? 

  Thanks in advance for any information! 

  Best regards,

  Olivier.
