A lot of the time the metadata accuracy is up to the original uploader. IA's upload system doesn't magically fill in all the metadata details for an item.
Also doesn't allow other to update metadata or even submit for review.
Wikidata has a property for Internet Archive ID, so it wouldn't be conceptually hard to construct a parallel metadata store there, but it would involve hundreds of millions of triples so it's definitely "hard" in other senses.
