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=99405143#Value_statistics. Having daily data like that for all properties would be quite useful.

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,
Eric

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

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.
