| Description: |
Object-oriented methodologies like UML (Unified Modeling Language)
are increasingly used for the design and development of distributed
systems. BDL (Behavioural Description Language) [Talpin-et-al-98]
is a view of UML enriched with behavioural description facilities.
BDL has a formal semantics that is suitable for simulation,
verification, and code generation from object-oriented specifications.
A BDL specification is a collection of classes connected via various relations, each class being represented as a directed graph whose nodes are (valued) events. BDL classes and communications can be interpreted in a synchronous or asynchronous way. Starting from a denotational semantics of BDL, four different operational semantics of BDL have been developed: synchronous small-step, synchronous large-step, asynchronous, and synchronous-asynchronous. These semantics have been implemented using the OPEN/CAESAR generic environment for on-the-fly verification of CADP. |
| Conclusions: |
The connection of BDL to OPEN/CAESAR allows to benefit from all the
simulation, verification, and test generation facilities already
implemented using OPEN/CAESAR. Moreover, work is ongoing to build
a front-end for UML enriched with BDL is under development, by
extending the tool UMLAUT [Jezequel-Pennaneac-97] for analysing
and transforming UML programs.
