 Let's look at the first 10 columns of the DetailedCatalog table.  Again, note that calling the columns attribute sends another query to the service to ask for the columns.

-The PyVO method to get the columns will automatically fetch all the meta-data about those columns.  It's up to the service provider to set them correctly, of course, but in this case, we see that the column named "MatchRA" is identified with the UCD "pos.eq.ra".

 Lastly, if you have a table of results from a TAP query (and if that service includes the UCDs), then you can get data based on UCDs with the getbyucd() method, which simply gets the corresponding element using fieldname_with_ucd():
