XM 2013 - International Workshop on Extreme Modelling

Raising the level of abstraction and using concepts closer to the problem and application domain rather than the solution and technical domain, requires models to be written with a certain agility. This is partly in contrast with MDE whose conformance relation is analogous to a very strong and static typing system in a current programming language. For instance EMF does not permit to enter models which are not conforming to a metamodel: on one hand it allows only valid models to be defined, on the other hand it makes the corresponding pragmatics more difficult. Thus there is an increasing need for more disciplined techniques and engineering tools to support flexibility in several forms in a wide range of modeling activities, including metamodel, model, and model transformation definition processes.
The workshop would aim at better identifying the difficulties in the current practice of MDE related to the lack of flexibility, and soliciting con- tributions of ideas, concepts, and techniques also from other areas of software, such as that of specific language communities (e.g., the Smalltalk and Haskell communities, and the dynamic languages community) which could be useful to revise certain MDE fundamental concepts, such as the conformance relation.
