OK...so fundamentally there is a mismatch here. If I read the "primary
file spec" from an index file, assuming it is in the proper format
(ending in .LBL), then I have no way of using PdsFile.from_filespec() to
look it up and get a viable ViewSet from it, since ViewSets explicitly
don't work with the .LBL extension.
So either we need to change PdsFile to look up Viewables when the
extension is .LBL, or we need to change the extension of the primary
file spec before sending it to PdsFile for lookup. Or is there already
some automated way to ask PdsFile for the "primary data product" which
DOES have a ViewSet?
There's also the problem that Cassini ISS and Galileo SSI do NOT use
.LBL as the extension in the index files. That means that, in OPUS, some
observations have a primary file spec ending in .LBL and some end in
.IMG. Do we want to make these consistent by having the import pipeline
switch the extension to all be .LBL? Or do we want to keep the OPUS
database consistent with what's actually in the PDS archives?

OK, I remember now why I did this and it has to do with making sensible Viewmaster pages.
We can solve this problem by having a PdsFile attribute "primary_data_abspath" that returns the absolute path to the primary data file. Then...
...would do the trick. The problem is that the association between a random file and the primary data file is currently not easy to make unless you turn on "set_opus_lookups()", which is slow. I can fix that.
This will be the quantity that should be used as primary filespec, no matter what appears in the label. Also, PdsFile.from_abspath(primary_filespec).viewset will return a valid viewset.
OK, hopefully last question - do you really want abspath stored in the
OPUS database? That exposes our internal filesystem structure. Wouldn't
the logical_path, or better yet the logical_path with "volumes" stripped
off, be more appropriate?

yes, logical path after "volumes/".
