Containment hierarchy for DataRail. Individual arrays of primary or transformed data are gathered together into a MATLAB structure we call a compendium; multiple compendia are linked together into a project. Each compendium contains a unique name (UID), a short textual documentation, and a set of multi-dimensional arrays. Each array is stored together with simple metadata (name, free-text information, source, algorithm, and free parameters used in array creation). The representation follows the conventions of UML (Unified Modeling Language) format, indicating that a compendium contains one or more arrays, which contain one or more labels and zero or more parameters.
