Known data issues

Date inaccuracies

Some events do not have an exact date. In these cases we are providing a date range in which the provided rudimentary information can be encapsulated.

As an example, we would translate “March 1919” in the upstream data to begin_date: 1919-03-01 and end_date: 1919-03-31.

For records with exact date begin_date and end_date are identical.

Incomplete, unverified taxonomies

Taxonomy verification depends currently entirely on upstream providers. Unfortunately, we have quiet a few of incomplete, unverified, and even some incorrect taxonomies. We hope to improve this situation in the future by implementing our own taxonomy evaluation algorithm.
