Output from Special:EntityData is cached for 31 days. Looking at the code, it
seems we are not automatically purging the web caches when an entity is edited -
please file a ticket for that. I think we originally decided against it for
performance reasons (there are quite a few URLs to purge for every edit), but I
suppose we should look into that again.
You can force the cache to be purged by setting action=purge in the request.
Note that this will purge all serializations of the entity, not just the one

I found that Special:EntityData returns outdated JSON data that is not in
agreement with the page. I have fetched the data using wget to ensure that no
browser cache is in the way. Concretely, I have been looking at
where I recently changed the P279 value from Q217594 to Q16889133. Of course,
this might no longer be a valid example when you read this email (in case the
cache gets updated at some point).
Is this a bug in the configuration of the HTTP (or other) cache, or is this the
desired behaviour? When will the cache be cleared?
