Obliq is a lexically-scoped, distributed, object-based programming language. In Obliq, the migration of an object is proposed as creating a clone of the object at the target site, whereafter the original object is turned into an alias for the clone. Obliq ...
Transactions are commonly described as being ACID: All-or-nothing, Consistent, Isolated and Durable. However, although these words convey a powerful intuition, the ACID properties have never been given a precise semantics in a way that disentangles each pr ...

This paper studies the semantics of protocol modules composition and interaction in configurable communication systems. We present a semantic model describing the x-kernel, Cactus and Appia --- three frameworks that are used for implementing modular system ...
The purpose of the paper is to present our approach for specifying system behavior. Our approach is based on operation schemas and a system interface protocol (SIP). Operation schemas describe the functionality of system operations by pre- and post-conditi ...
Message ordering is a fundamental abstraction in distributed systems. However, usual ordering guarantees are purely syntactic'', that is, message semantics'' is not taken into consideration, despite the fact that in several cases semantic information a ...
The model-driven architecture approach (MDA) promotes software development as driven by a thorough modeling phase where application code is automatically generated from a platform specific UML model (PSM). The idea is that the PSM is itself derived from a ...

The semantics of UML [3] is for a large part given in English. The drawback of Eng-lish is its ambiguity, which makes it unclear and ambiguous. But the benefits of Eng-lish are its power and flexibility, which allow it to deal with a slightly inconsistent ...
This report presents the formal semantics of COALA, a design language based on the concept of Coordinated Atomic Actions (CA actions). COALA has been developped with the intent of providing a concrete language to express CA actions and thus facilitate the ...
