I don't have any data to agree or disagree with you about that, but most of the edits I have made have been for films. Most of those claims are immutable.

We commonly use the example of historic population values. MediaWiki software saves disk space by delta encoding edit histories. http://en.wikipedia.org/wiki/Delta_encoding I can probably think of at least 5 different ways we could arrange the schema of Wikidata to store information about US presidents, but I don't think using universal valid_from and valid_to values for every claim is the most efficient, natural, or flexible way to do so. > Date: Fri, 5 Apr 2013 00:08:00 +0200 > From: [email protected] > To: [email protected] > Subject: Re: [Wikidata-l] Page history and properties > > And what are you doing when you want the knowledge of the world from 5 > years ago?
