Checking http://miffteevee.co.uk/documentation/development/group__db__schema.html
states that " 'airdate' is a string representing the year of release
for movies and may have no meaning for other types of shows". This
agrees with how uk_rt presents <date> information in the listings.

I've checked today's uk_rt XML file to see how dates are being
included in the grabber data and whether there is any inconsistency.
The only programmes where the <date> element is present are theatrical
and TV films, one or two documentary films and multi-part TV dramas
presented as films, such as Columbo and Perry Mason. For such
programmes the date given is the release/copyright date - separate to
MythTV's concept of originalairdate - and they all seem to be fine.

Can you provide any examples of which programmes you are seeing
inconsistencies with?

I have a few years of archived data so I can look back for specific
programmes if you can provide them. Again, make sure that the data is
coming from the uk_rt grabber and not MythTV's import handling of the
data or its display in an OSD theme.

originalairdate is not available from the uk_rt grabber.

"If it were up to me" I would keep the release/copyright date separate
from airdate (year of this showing of the programme on TV) and
originalairdate (year of premiere showing of programme on TV in
locale), as the release date of a film or documentary is a different
concept to either of these other values.

One may have the scenario where a brand new documentary is released
and premiered on TV in the same year such that all three values
(release date, airdate and originalairdate) are the same, but these
values would be different often enough to warrant storing and handling
them separately.

To the best of my knowledge, all of the data that the Radio Times feed
provides is used by the uk_rt grabber in the way intended by the XMLTV
DTD.
