A list of unresolved issues related to SDRecord:
- What impact with the planned visibility in Glish of the aips++ Measures,
units and coordinate information have on data.desc?
- It should be possible to associate multiple data fields with
a single header - this would be particularly useful for
closely related data - such as that found in an image. This needs
to be described.
- History - SDCalc functions need to add to this. What does
it look like? How much bloat will this cause if users forget to
trim this record? Which functions should add to this - all functions which
add information to an SDRecord or alter existing information or
only those which alter existing information?
- The values listed above only cover some of the information which can
be found in a MeasurementSet. Is this a sufficient list? There is also
some information which is missing from the standard MeasurementSet.
At some point this deficiency should be corrected. What changes would be
necessary to a MeasurementSet so that it would be easy to store the
more flexible data structure of an SDRecord (i.e. that in data.desc)?
