dc.description.abstract | In the context of web service procurement (WSP), temporal–awareness
refers to managing service demands and offers which are subject to validity periods,
i.e. their evaluation depends not only on quality of service (QoS) values but
also on time. For example, the QoS of some web services can be considered critical
in working hours (9:00 to 17:00 from Monday to Friday) and irrelevant at any
other moment. Until now, the expressiveness of such temporal–aware specifications
has been quite limited. As far as we know, most proposals have considered
validity periods to be composed of a single temporal interval. Other proposals,
which could allow more expressive time–dependent specifications, have not performed
a detailed study about all the underlying complexities of such approach,
in spite of the fact that dealing with complex expressions on temporality is not a
trivial task at all. As a matter of fact, it requires a special design of the so–called
procurement tasks (consistency and conformance checking, and optimal selection).
In this paper, we present a constraint–based approach to temporal–aware
WSP. Using constraints allows a great deal of expressiveness, so that not only demands
and offers can be assigned validity periods but also their conditions can be
assigned (possibly multiple) validity temporal subintervals. Apart from revising
the semantics of procurement tasks, which we previously presented in the first
edition of the ICSOC conferences, we also introduce the notion of the covering
set of a demand, a topic which is closely related to temporality. | |
