This paper reports on our experiences with using the emerging web service technologies and tools to create a demonstration information broker system as part of our research into information management in a distributed environment. To provide a realistic context we chose to study the use of information in the healthcare domain, and this context sets some challenging parameters and constraints for our research and for the demonstration system. In this paper we both report on the extent to which existing web service technologies have proved to be mature enough to meet these requirements, and also assess their current limitations.
