Multi-Organisational Web-Based Systems (MOWS) are becoming very popular in the Internet world. It would be desirable for such systems to be quality-aware, and this feature turns the problem of selecting the web services of which they are composed into a complex task. The main reason is that the catalog of available services that meet a set of functional requirements may be quite large, and it is subject to unexpected changes due to the inherent volatility of the Internet. Thus, such systems need an infrastructure able to select the best services at run time so that they can deliver their functionality at the best possible quality level. In this article, we present a proposal that aims at being the core of a run-time system able to support the construction of quality-aware MOWS.
