Metadata Template

This metadata template file is a label mock-up designed to demonstrate the order of SB dictionary classes in a label, and the cross-referencing needed to properly identify the various data objects that might be present. It does not necessarily reflect any “real” case, and in general any cutting and pasting done needs to include a fair amount of intelligent interpretation to the real-life circumstances of the data.

It does, however, serve as a “working model”, in the sense that it will validate against the SB schemas, and a label designer can thus experiment with it for use in real labels.

Some comments are included regarding cardinality and required/optional status in key places. The definitive source for cardinality information, however, is always the schemas - not the examples.

              The scenario here is a file which contains three cubes - one for data,
              one for error, and one for quality - in which the planes correspond.
              There is also a single bad pixel map image that applies to all image
              frames. There are five planes defined for each cube. (offsets and
              sizes have been ignored.)
