The application is an intelligent agent market place, where buyer and seller agents cooperate and compete to process sales transactions for their owners. The market place manager acts as a facilitator by giving necessary information to agents and managing communication between agents, and also as a mediator by proposing solutions to agents or stopping them to get into infinite loops bargaining back and forth. The buyer and seller agents range from using hardcoded logic to rule based inferencing in their negotiation strategies. However these agents must support some communication skills using KQML or FIPA-ACL. So in contrast with other approaches to multiagent negotiation, we introduce an explicit mediator (market place manager) into the negotiation, and we propose a mediation process based on dependence theory (C. Castelfranchi, 1994) implemented by the manager.","PeriodicalId":287840,"journal":{"name":"Proceedings.

The Object Management Group (OMG) Business Object Domain Task Force (BODTF) was the initial focal point for standardization of a Business Object Component Architecture (BOCA). Priming this effort required joint work with the Accredited Standards Committee X3H7 Object Information Management, and their joint sponsorship of the OOPSLA Business Object Component Design and Implementation Workshop for the years 1995-99. Emergence of W3C XML standards will further enhance BOCA and enable a distributed business object system that provides interoperability between disparate enterprise applications on the Web.","PeriodicalId":287840,"journal":{"name":"Proceedings.

To ease the development of such applications, software support to facilitate coordination and communication is needed. This paper describes an object-oriented system that provides software support for different aspects of application development, namely session management, coordination and information exchange. In particular, the paper proposes a coordination service as a building block for developing distributed applications. A set of processes or agents that need to coordinate their actions can supply a coordination specification to this service. The service then performs the appropriate lower-level communication to coordinate the actions of the processes as per the specification. We believe that such a service should be available as part of the basic infrastructure for developing Web-based distributed applications. Our framework has been implemented in Java and incorporates the notion of role types to accommodate application development in an open system.","PeriodicalId":287840,"journal":{"name":"Proceedings.

Current approaches are based on mark-up scripts. While mark-up scripts possess several advantages in the simplicity of representation and interchange of structured documents among loosely coupled systems, what they originally have been created for, they have disadvantages when applying them as the silver bullet for distributed data or object modeling, especially for generic multimedia management. We first describe the deficiencies arising from the notion mentioned above, then present a generic approach to alleviate those deficiencies. After that, we describe the realization of the generic approach using a model and an architecture. Then, we show the integration of markup scripts into the concept presented.","PeriodicalId":287840,"journal":{"name":"Proceedings.

We demonstrate how component technology can be effectively applied to the process of building collaborative applications in the Web environment. In order to support development of collaborative tools, the components must satisfy a set of requirements inherent for a synchronous collaboration environment. The distribution of arbitrary events and objects, the access to the collaborative session state, and the means of synchronizing operations on the shared resources must be provided. Tango Beans is a set of components based on the Tango Interactive framework that has been implemented to facilitate rapid development of collaborative applications. We explain how Tango Beans work and how they can be used to develop collaborative tools for synchronous distance learning and Web conferencing.","PeriodicalId":287840,"journal":{"name":"Proceedings.

Securing these resources is thus vital for their survival. Enterprises nowadays want to have their organizational structure mirrored into their security policy. Role based access control (RBAC) has proven to be an essential tool in this process. Although Microsoft based systems have acquired a large part of the market, it seems that the old but very reliable Unix is getting a boost as well. Unfortunately, standard Unix does not implement RBAC. In this paper a solution to this problem is described that uses the Novell SESAME security architecture. To this end the paper introduces a new RBAC model.","PeriodicalId":287840,"journal":{"name":"Proceedings.

Great care should be taken by users when they make a decision to trust a CA. Unfortunately, the average user will rely on the software to provide an appropriate security warning when something has gone wrong and therefore may not give much thought to the decision when performing such a security operation. The updating of a CA certificate is an issue that needs to be accomplished in a secure manner with little or no intervention by a user. Techniques are now in use that can allow for update of a CA's certificate. The Secure Electronic Transaction's (SET) root certificate update method is just one example, but in a specialized case. This paper discusses a practical solution that potentially any CA could use to provide a secure in-band update of a CA's X.509 v3 certificate into a user's personal security environment (PSE). A method is also discussed that Java programmers can use for update of self-signed X.509 v1 personal certificates in Java keystores as well.","PeriodicalId":287840,"journal":{"name":"Proceedings.

Also, distributed projects cannot be planned centrally, especially if the involved parties are individual companies with their own areas of responsibility (as is the case in virtual software corporations). On the other hand, certain aspects of the overall plan and schedule (milestones & deadlines, project progress) need to be available to all concerned parties. We present an approach to support distributed planning and scheduling, as well as the subsequent (also distributed) plan execution, in one system. The approach enables us to support interleaved planning and plan enactment, allowing the user to change the plan and schedule while the project is already under way. This facilitates the task of keeping the plan up to date, avoiding the complete invalidation of the plan as is often the case in conventional projects soon after enactment has started.","PeriodicalId":287840,"journal":{"name":"Proceedings.
