Different FIPA-compliant agent development platforms are available for developing multiagent systems. FIPA compliance ensures interoperability among agents across different platforms. Although most agent implementation platforms provide some form of white- and yellow-page functionalities to advertise and identify agent roles and descriptions, there are no clear architectural standards that define how an agent community can effortlessly adapt to operate in a federated information system (FIS) where new content sources are constantly added or changes are made to existing content sources. This chapter presents a framework based on the semantic Web vision to address extensibility in a loosely coupled FIS.

As a term used to denote the ability of defence systems to collaborate, interoperability has emerged as one of the most important capacities of information systems, during the last 30 years. Being important at organizational, process and semantic levels, interoperability soon became a key characteristic of information systems and services, both in the private and public sector. As a crucial prerequisite for automated process execution leading to “one-stop” electronic services and promising dramatic increase in productivity for enterprises of any size, interoperability has been systematically sought after, since the dawn of the 21st century: standardization frameworks, guidelines at enterprise level, data schemas and techniques to tackle the problem of non-communicating systems or organisations started to appear. In parallel, most international software, hardware and service vendors created their own strategies for achieving the goal of open, collaborative, loosely coupled systems and components. This chapter goes beyond the presentation of the main milestones in this fascinating quest for collaboration between people, systems and information: it attempts to describe how this new interdisciplinary research area can transform into a vibrant scientific domain, by applying the necessary method and tools. To achieve that, the chapter presents the ingredients of this new domain, proposes its needed formal and systematic tools, explores its relation with neighbouring scientific domains and finally prescribes the next steps for achieving the thrilling goal of laying the foundations of a new science.

Many (especially the large) software systems tend to be virtual peer-to-peer (P2P) networks of permanent autonomous services (e.g., e-government should be supported by the network of information systems of individual offices). The services are loosely coupled, a service can join/leave the system quite easily. We call such networks software confederation (SWC). The paradigm of the SWC is orthogonal to the paradigm of the object-oriented methodology. The architecture of SWC is an engineering necessity in the case of global or very large information systems (IS) and provides many software engineering advantages like incremental development, openness, modifiability, maintainability, etc. SWC is a necessity in many other cases. SWC supports the trend of large enterprises or modern states to be decentralized, dynamic, and able to work in the time of globalization. Software confederations are the result of the tendency to globalization, and at the same time, the tool allowing of implementation of IS for a globalized society. SWC changes basic features of a CEO’s work as well as a CIO’s. In both cases, it supports the decentralization. This paper discusses the motivation of software confederations, the techniques of their design and implementation, including the use of XML (inclusive SOAP-UDDI), their software engineering advantages, relation to object-oriented technology and methodological consequences of their use. The main conclusion is that the concept of SWC is the crucial for the future software and information technologies and substantially changes the management tasks of the CIO and CEO.

This chapter explores the potential for the application of agent technology to evolve an information system. In particular, the use of agents to evolve an educational subject management application is viewed in relation to an on-going project. Such software forms part of a courseware information system currently in use, and being further developed at Victoria University. Agent software is an emerging technology that has its roots in artificial intelligence research. With the recent proliferation of “agent” applications in areas such as e-commerce and Internet marketing, many agent applications fall squarely in the domain of Information Systems. Although there is little consensus at present regarding the nature and capabilities of software agents, agent technology may have the potential to advance Web-based subject management courseware to a further evolutionary stage.
