Abstract: The Model Driven Engineering (MDE) paradigm aims to deal with increasing complexity
in software development and maintenance. It focuses on using models to specify software
systems and on automating model manipulations with tools.
The goal of this thesis is to define and realize an open, distributed environment
supporting MDE. This environment, called ModelBus, intends 1) to support collaborative
model manipulations by multi-developers, and 2) to provide interoperability between
heterogeneous tools involved in MDE projects. To achieve the first objective, ModelBus
offers diff/merge mechanisms for models, and, for the second objective, ModelBus offers
mechanisms for exchanging models and for invoking services among tools.
The major problems addressed by ModelBus concern scalability regarding large
specifications of complex systems. Given that a set of models describing a system is a large
object graph (in the order of GBs), whose links represent relations among models (e.g.
traceability, view relationships), the following problems can arise: 1) Memory insufficiency
for manipulating the entire graph, and 2) link inconsistencies (dangling links) caused by
concurrent model manipulations. To solve those problems, ModelBus partitions a system
specification into models, and manages link consistency between those models.
