It mentions it here, but I’ve been doing comments in the setlist. Is this actually in the schema and not implemented on the event edit page?
Events are similar to artists in that you don’t create the annotation from the main edit form, but with a separate “Add annotation” link from the sidebar.

I did not see that, thanks
Well… I found a bug in musicbrainzngs. It doesn’t think ‘annotation’ is proper include for an event even though it is. A tiny edit later and… I still have something broke. It’s late, I’m tired..
mbxml.py in musicbrainzngs needed a tiny edit, too. Ok, now I can sleep…

That is basically abandonware by now, so I’m not surprised - I expect it has a lot more stuff missing.

Hi, are there dox that describe how to use Picard’s album.tagger.webservice._get_by_id() for a plugin? Or is this “Use the source, Luke”? With the name starting with an underscore, that makes it private, right?
Basically, I need to redo this file for webservice. I’m imagining something overly complex with condition waits
def get_release_group (ws, mbid):
# if pending condition.wait
# if not error return release_group_cache[mbid]
# elif timeout retry?
# else
# set pending
# ws.get_release_group_by_id(...,on_complete,...)
#
# def on_complete(response, reply, error):
# if not error
# release_group_cache[mbid] = response['release_group']
# unset pending
# condition.set ?
pass
Oh, I can get URLs, too. This is fancy. Cover art, next? Maybe 
Should I just build my own?
from picard.webservice.api_helpers import APIHelper
class PluginCachingWebService(APIHelper):
def __init__ (self, webservice):
super().__init__(webservice)
self.release_group_cache = dict()
self.release_cache = dict()
self.event_cache = dict()
self.place_cache = dict()
self.area_cache = dict()

self.release_group_cache = dict()
self.release_cache = dict()

@Sophist I need your advice on what to do about replacing musicbrainzngs in a plugin
It’s working quite well pulling apart all the events on this release

Oh, wow, neet. I can do this
EDIT: maybe not…
EDIT2: Gotcha! https://eventartarchive.org/event/30f5416d-bb62-4827-9e9f-605a1368cd5c
does webservice do smart caching by doing a HEAD request first, then a following GET if Last-Modified is newer in the headers?
