I'm looking for data set with entry values being corrected, and those correction are documented with previously incorrect values available as well. This can be in the form of errata, diff files, or old and new versions of the same data set. Ideally I would prefer data set consisting of numerical/ categorical values that can be used by simple machine learning algorithms like logistic regression. The more the better. Thanks.

Wikipedia and GitHub store revision history. Both have APIs, data dumps, BigQuery tables.– Anton TarasenkoMar 7, 2017 at 0:56

Does Wikipedia have any 'data' data?– ChubbyRubyMar 7, 2017 at 1:39

They have tables and infoboxes. Not sure if Wikidata stores revisions. But every WP page has "View history" pages with older revisions of in-text tabulated data.– Anton TarasenkoMar 10, 2017 at 19:16

The Open-APC data consists of datasets

The data is freely available and has the GitHub versioning and the GitHub API.
