A Composite Web Service Supporting User Context to Provide an Adapted Remote Control of High Technology Instruments

In this paper, we are aiming at providing a complete, plate-form independent, framework, for the remote control of high technology instruments. This is lead by the idea of sharing resources (instruments in this use-case) between entities, each exploiting of course their own information system. Mainly, to be generic enough to satisfy the corresponding genericity of resources addressed, the sharing must be done under certain constraints, which are security, scalability, authentication, "real time" access, Multi-Platform and Multi-Users access. The purpose of the article is to discuss the possible use of Web services for the skeleton of such a generic framework, with the issue of providing an adapted service to the user depending on the context of utilization (i.e. depending on the role the user is playing in the session). http://www.istase.com/satin/eINST.html.
