What about monthly/dump-based aggregated property
usage statistics?
Property usage statistics would be very valuable, Dimitris. It would
help inform community decisions about how to steer changes in property
usage with less disruption. It would have other significant benefits as
well.
Getting daily counts like
https://www.wikidata.org/wiki/Wikidata:Database_reports/Popular_properties
back up and running would be a good place to start. That report hasn't
been updated since October 2013. We could go further by showing counts
for all properies, not just the top 100.
More detailed data would be great, too. Wikidata editors recently
posted a list of the most popular objects for 'instance of' (P31) claims
at
https://www.wikidata.org/w/index.php?title=Property_talk:P31&oldid=9940…tics.
Having daily data like that for all properties would be quite useful.
Thanks for the suggestions. I will put all of these on the list for the
Wikidata Toolkit development. Providing up-to-date analytics of this
kind is a good basic use case for this project. (Btw, the project starts
officially in mid Feb and runs for six months, but we will start working
before that already; but there will be a bit more planning before we
start hacking).

If anyone does end up doing something like this, I would recommend
archiving the data at
http://dumps.wikimedia.org/other/ in addition to
posting it in a regularly updated report in Wikidata.
Cheers,

People would be able to check property trends or maybe subscribe to
specific properties via rss.

Hi, a problem seems (not very surprisingly) to
emerge into
Wikidata : the
managing of the evolution of how we do things on
Wikidata.
Properties are deleted, which made some consumer of the datas
sometimes a
little
frustrated they are not informed of that and
could not take
part of the discussion.
They are informed if they follow the relevant channels. There's
no way to inform
them if they don't. These channels can very likely be improved, yes.
That being said: a property that is still widely used should
very rarely be
deleted, if at all. Usually, properties would be phased out by
replacing them
with another property, and only then they get deleted.
Of course, 3rd parties that rely on specific properties would
still face the
problem that the property they use is simply no longer used
(that's the actual
problem - whether it is deleted doesn't really matter, I think).
So, the question is really: how should 3rd party users be
notified in changes of
policy and best practice regarding the usage and meaning of
properties?
That's an interesting question, one that doesn't have a
technical solution I can
see.
