In a Grid system, users typically express their requests as constraints and preferences using a well-known set of terms defined in an information model and describing the resource characteristics. This description is used by the selection service provided by the Grid middleware that implements the mapping functionality of abstract resources to physical ones.

In this area, I’m working on a query language enabling the expression of the user requirements and preferences over XML-based represetantion of Grid resources.This was the core topic of my PhD Thesis.
