Composing Web Services in an Open World: QoS issues"

Talk Abst

ract:

I shall review problems related to QoS when composing Web servi

ces orchestrations. I shall first develop the case of response time and the

n propose generalization to systematic and flexible QoS management for orch

estrations. I shall review several problems:    1/ the pa

radigm of contracts to deal with the open world of Web services, 2/ monoto

nicity of orchestrations, 3/ how to develop a generic framework for QoS ma

nagement. The whole is illustrated on Orc. Time permitting, I shall also b

riefly discuss why we also pursue a parallel track of Active XML documents

for combined data and workflow management at the Web scale.

This
is joint work with Sidney Rosario, Claude Jard, Stefan Haar, and
