Can you think of how the event would be structured if you wanted to apply a review to a movie object?
Would you be able to aggregate all reviews for that one object then?
Discussion
Aggregation in order to get an average score (for example) would have to be done on the client's side, but for structuring them based on https://github.com/nostr-protocol/nips/pull/532 I would do something like:
{"tags": [["r", "https://www.themoviedb.org/movie/197-braveheart"], ["L", "review"], ["l", "movie", "review"], ["quality", 0.9]], content: "I like freedom"}
This might be displayed as a 4.5 star review for Braveheart, searchable by namespace ("review") and label within that namespace ("movie").
