CFAFragment file and format attributes when they are same as the CFA file

[davidhassell]

Hi Neil,

When the fragment resides in the same file as the aggregated data variable, the file and format are both encoded as missing values in the CFA file, and the corresponding CFAFragment attributes are both None.

The application building the aggregated data just cares about a file name and format, it shouldn't need to concern itself with how the CFA data was distrubuted across files. Would it be possible in this case to instead set these CFAFragment attributes to CFADateset.path and CFADateset.format respectively?

Of course if the address is also missing data (None) then we would want to keep file and format as None, too, to indicate a wholly missing data fragment.

What do you think?

Thanks,
David
