Problem: (Lack of) Podcast & Episode identification leads to duplicates

[keunes]

From the meeting notes:

• Duplicate episodes/subscriptions are an issue. They use the media URL as an identifier for an episode, but if the file changes due to reupload or something else this creates a brand new entry. Syncing these changes is difficult.
• User documentation is lacking. e.g.:
  • If podcast creators change GUID and URL for an episode, there isn’t an agreed-upon behavior for the API or for clients consuming the episodes.
  • If an action is stored locally, and a conflicting action is received from the server at later stage; what happens on sync? Can take inspiration from listenbrains scrobbles.
• Subscription lists can duplicate due to URLs not being updated reliably.
• There is no agreed-upon way to handle updating URLs, and this is mostly being handled by clients
