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)
