Both DataOrigin and mivot require to access VOTable fragments which are not available in astropy.table.Table.

DataOrigin is available in the data_origin module of astropy. and mivot is available in the MivotBlock module

However, astroquery (for instance astroquery.Vizier) can't access these votable fragments.

For instance: (VizieR example, but it is the same with other Services)

>>> from astroquery.vizier import Vizier
>>> vizier = Vizier()
>>>exoplanets_star = vizier.get_catalogs("J/ApJ/788/39")[0]
>>>type(exoplanets_star)
<class 'astropy.table.table.Table'>
