In our previous work, we introduced a novel method for exchanging and querying complete genome data by representing them as structured documents. We defined an XML-based genome language called GXML, and a genome-oriented query language called GQL for making biologically meaningful queries on GXML genome documents. In this paper, we extend GQL with aggregate functions and sorting capability to further increase the usefulness of our method. We discuss the additional syntax and present several examples of biological queries that require aggregation. We are currently investigating algorithms for implementing the new constructs in a prototype system.
