Composing adaptable-resources for answering complex queries in distributed systems
Yacine Sam, Omar Boucelma · 2008
The Internet and grid technologies development was accompanied by an exponential proliferation of the resources to which a customer (user, program, community) may have access to. These resources (data sources, software components, Web services, physical devices, etc) are often offered in an adaptable/negotiable manner, i.e., under different configurations (variants), in order to satisfy different customers' needs. They are in that case called adaptable-resources. We present in this article some mechanisms that allow the composition of resources' variants, in order to answer complex queries, that generally require a combination of several adaptable-resources.
