Architecture for Provenance Systems
This document covers the logical and process architectures of provenance systems. The logical architecture identifies key roles and their interactions, whereas the process architecture discusses distribution and security. A fundamental aspect of our presentation is its technology-independent nature, which makes it reusable: the principles that are exposed in this document may be applied to different technologies

Supporting telecom business processes by means of workflow management and federated databases
This report addresses the issues related to the use of workflow management\ud
systems and federated databases to support business processes that operate on\ud
large and heterogeneous collections of autonomous information systems. We\ud
discuss how they can enhance the overall IT-architecture. Starting from the\ud
OSCA architecture, we develop an architecture that includes workflow\ud
management systems and federated databases. In this architecture, the notion of\ud
information systems as a monolithic entity disappears. Instead, business\ud
processes are supported directly by workflows that combine presentation\ud
blocks, function blocks, and data blocks. We address the specific issues of\ud
transaction management and change management in such an architecture
Architecture of autonomous systems
Automation of Space Station functions and activities, particularly those involving robotic capabilities with interactive or supervisory human control, is a complex, multi-disciplinary systems design problem. A wide variety of applications using autonomous control can be found in the literature, but none of them seem to address the problem in general. All of them are designed with a specific application in mind. In this report, an abstract model is described which unifies the key concepts underlying the design of automated systems such as those studied by the aerospace contractors. The model has been kept as general as possible. The attempt is to capture all the key components of autonomous systems. With a little effort, it should be possible to map the functions of any specific autonomous system application to the model presented here
An Architecture for Information Commerce Systems
The increasing use of the Internet in business and commerce has created a number of new business opportunities and the need for supporting models and platforms. One of these opportunities is information commerce (i-commerce), a special case of ecommerce focused on the purchase and sale of information as a commodity. In this paper we present an architecture for i-commerce systems using OPELIX (Open Personalized Electronic Information Commerce System) [11] as an example. OPELIX provides an open information commerce platform that enables enterprises to produce, sell, deliver, and manage information products and related services over the Internet. We focus on the notion of information marketplace, a virtual location that enables i-commerce, describe the business and domain model for an information marketplace, and discuss the role of intermediaries in this environment. The domain model is used as the basis for the software architecture of the OPELIX system. We discuss the characteristics of the OPELIX architecture and compare our approach to related work in the field
