To increase the assurance with which agents can be deployed in operational settings, we have been developing the KAoS policy and domain services. In conjunction with Nomads strong mobility and safe execution features, KAoS services and tools allow for the specification, management, conflict resolution, and enforcement of DAML-based policies within the… (More)

SUMMARY Many organizations spend a lot of time and effort analyzing the knowledge people within the organization use to perform their work. This is often done to make the work process more efficient, or to manage the knowledge resources (man, machine, or other) better. To do this, the first thing that is often done is to model the current state of the work… (More)
In this paper, we describe the Compendium methodology and suite of tools. Compendium is the result of over a decade's research and development at the intersection of collaborative modeling, organizational memory, computer-supported argumentation and meeting facilitation. We claim that Compendium offers innovative strategies for tackling several of the key… (More)
W ork systems involve people engaging in activities over time—not just with each other, but also with machines, tools, documents, and other artifacts. 1 These activities often produce goods, services, or—as is the case in the work system described in this article—scientific data. Work systems and work practice evolve slowly over time. The integration and… (More)
We have developed a model-based, distributed architecture that integrates diverse components in a system designed for lunar and planetary surface operations: an astronaut's space suit, cameras, all-terrain vehicles, robotic assistant, crew in a local habitat, and mission support team. Software processes (" agents ") implemented in the Brahms language, run… (More)
This paper explores a method to realize an anonymityconscious P2P data sharing network. The proposed network lets users extract other users' data that match the users' profiles, thereby providing them a collaborative filtering-based data recommendation. Our proposal realizes such a recommendation scheme without forcing the users to disclose their profiles.… (More)
Introduction At NASA we develop new work systems for exploring extraterrestrial bodies, and scientific research in space. The work performed during a Space Shuttle flight is the result of a developed work system. The International Space Station will need a new and different work system, not yet fully developed. When eventually we will go to Mars we need a… (More)
