Why All RSS Generators Repeat Tags (Author, Explicit) at Item Level Too?
Why does every RSS feed I have found redundantly show the tags of itunes:author and itunes:explicit at both the channel level and in every single episode?
If the itunes:author is "Jane Smith Studios" and an individual episode has no changes to that, then why does the RSS feed show the tag itunes:author in the channel *and also again* in the item?
When there is no change from channel to item for the image or the location, then we do *not* repeat that identical info for each individual item (episode).
But!
For some reason, a channel with the same author at both the channel (series) level and episods level for every episode will repeat that information.
The case is the same for itunes:explicit. If my channel (series) is clean, then the channel tag for itunes:explicit is false. Yet every episode re-declares that the episode is also clean.
Why repeat these tags in every item (episode) if *neither changes* and if the tags (itunes:author, itunes:explicit) *already* appeared at the channel level?
(Is there some historical reason to Apple or iTunes using or demanding this?)
Thank you for reading.
