Abstract. There is an increasing trends towards distributed and shared repositories for storing
scientific datasets. Developing applications that retrieve and process data from such repositories
involves a number of challenges. First, these data repositories store data in complex, low-level
layouts, which should be abstracted from application developers. Second, as data repositories are
shared resources, part of the computations on the data must be performed at a different set of
machines than the ones hosting the data. Third, because of the volume of data and the amount of
