• Northwestern and DIL: One large compound object for image data streams and a sibling object containing VRA Work type metadata
    • DELIV-OPS datastream stores crop information
    • ARCHV-IMG and ARCHV-EXIF are archive copies of TIFFs only (not for display), they are EXTERNAL DATASTREAMS, external to have different storage strategy for larger files
    • VRA Work object (descriptive metadata)
      • describes the thing that is actually photographed (eg. a building)
      • in UI shows related images using VRA work relationships (i.e.. sculptor, painter)
    • Duke, U of Oregon, and Oregon State interested in using DIL code (and interested in Hydra)
