The context of this paper is Enterprise Architecture (EA). EA is a multi-disciplinary approach that allows dierent specialists to design new business and IT systems and focuses on the integration of these systems. Our group develops a specic EA method that ...
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 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 ...
This paper describes the techniques and tools developed to support the construction of CO-OPN specifications (Concurrent Object Oriented Petri Nets) [7] and the kind of semantics that are needed for each part of the environment. CO-OPN is a specification l ...
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 ...
This paper studies the semantics of protocol modules composition and interaction in configurable communication systems. We present a semantic model describing Cactus and Appia -- two frameworks that are used for implementing modular systems. The model cove ...
The Object Constraint Language (OCL) has been for many years formalized both in its syntax and semantics in the language standard. While the official definition of OCL’s syntax is already widely accepted and strictly supported by most OCL tools, there is n ...

Effective opportunistic search in visual interfaces for large information collections, such as documents, Web pages, and annotated images, often requires domain knowledge that the information seeker does not have. Relevant semantic information, such as met ...
This paper describes a novel approach for obtaining semantic interoperability among data sources in a bottom-up, semi-automatic manner without relying on pre-existing, global semantic models. We assume that large amounts of data exist that have been organi ...
