pyvo.io.vosi.vodataservice.Table.describe() fails for description None

[trjaffe]

If the metadata for the table description is empty in a registry query result, then if you call the describe() method, it doesn't exit gracefully:

heasarc_tap_services=vo.regsearch(servicetype='tap',keywords=['heasarc'])
heasarc_tables=heasarc_tap_services[0].service.tables
print(type(heasarc_tables['abellzcat']))
<class 'pyvo.io.vosi.vodataservice.Table'>
heasarc_tables['abellzcat'].describe()

leads not to printing of None or something but an exception on a AttributeError.

And the related question, why do all of the ones I check have None for the description? Is PyVO getting the wrong thing?

[trjaffe]

Think we should bump up the priority on this, specifically the second question, why no descriptions are appearing at all. Everything starts with looking for the tables you want, so the description is important.

The fix in pyvo has been merged. HEASARC has fixed all its descriptions so that they are all populated. IRSA still needs to fix the descriptions.
