Adaptive Distributed Applications in Java (ADAJ ) is a platform developed for execution of distributed applications in Java. The objectives of this platform is to facilitate application design and to efficiently use the power of distributed computing. The ADAJ offers both a programming and an execution environment. In the latter it implements object(More)
The Agents in Grid project is devoted to the development of an agent-based intelligent high-level Grid middleware. In the proposed system, all data processing is ontology-driven, and initially was based on an in-house developed mini-ontology of the Grid. Our recent analysis has indicated that we should adapt and utilize the Grid ontology developed within(More)
Currently, we are developing an agent based infrastructure for resource management in Grids. In the past our attention was focused on high-level processes involved in agents selecting a team to join or a team to execute a job. In this note we consider how the proposed agent-based system can interact with an actual Grid middleware. As our initial target we(More)
Ontology engineering, despite considerable progress, is still relatively new and dynamically evolving discipline. As a result, the universal standards for creating and/or editing an ontology, have not been established. This leads to problems with reusing and updating existing ontologies. It also makes writing an ontology from scratch seem like a good idea.(More)
This work concerns part of our project, devoted to the development of an agent-team-based Grid resource brokering and management system. Here, open issues that have to be addressed in the process, concern agent team preservation. In our earlier work it was suggested that this can be achieved through mirroring of key information. Here, we discuss in detail(More)
One of the important issues when designing systems that are to use ontologies and semantic data processing is, how to build the interface between the user and the system. The aim of this paper is to discuss technical details of OntoPlay, a flexible interface for ontologybased systems. OntoPlay allows creation of dynamical interfaces that allow(More)
Resource management and job scheduling are important research issue in computational Grids. When software agents are used as resource managers and brokers in the Grid a number of additional issues and possible approaches materialize. The aim of this chapter is twofold. First, we discuss traditional job scheduling in Grids, and when agents are utilized as(More)
