There are increasing numbers of systems and research projects involving software agents and mobile agents. However, there is no reference model or conceptual framework to compare the resulting systems. In this paper, we propose a reference model to identify, classify and evaluate mobile agent systems having a significant set of non-trivial architectural(More)
The suggestion that in software development projects the emphasis must be on the project management (RE), requirements engineering, and design activities, and consequently efforts in production activities – such as traditional software programming and testing – should be minimised and performed as automatically as possible is discussed. The ProjectIT(More)

In this paper we continue arguing that persistence is a fundamental requirement to support the development of next-generation agent-based applications. After a general overview of mobility and persistence to clarify the main issues discussed in the paper, we propose a tentative list of facilities that should be supported by persistent mobile agent systems.(More)
—Requirements Engineering (RE) is about achieving a shared understanding about the software system to be built. No withstanding the importance of other RE activities, requirements specification deserves special attention due to its documentation purposes: to communicate requirements, someone has to write them down. In this paper we present RSLingo, a(More)
XIS is a R&D project which mission is to analyze, develop and evaluate mechanisms and tools to produce information systems from a more efficient and productive way than it is done currently. XIS project is influenced by MDA reference model, and is mainly based on three principles: it is based on high-level models specification; it is based on generative(More)
XIS 1 is a R&D project which main mission is to analyze, develop and evaluate mechanisms and tools to produce information systems from a more abstract, high-level, efficient and productive way than it is done currently. XIS project is influenced by MDA reference model, and is mainly based on three principles: namely high-level models specification;(More)
