Frequently Asked Questions¶
This part of the documentation answers common questions about the Open Raadsinformatie API.
Dates are fickle things. A date is a particular point in time, and can be represented in very many ways. In addition, dates have gradations in precision. For example,
Jan. 1970 is not as precise as
1 January 1970 00:00:00 is.
The different data sources in the Open Raadsinformatie API expose dates with very different precisions (
Vr 20 mei 2015 18:00,
1 January 2010, etc.), often because that is as precise as the collection owner knows. In order to be able to reason about these dates, we opted to generate a full-fledged date anyway (so
Jan. 2010 becomes
2010-01-01:00:00:00), and store its
granularity alongside it. The granularity signifies how precise the date is known; it is an integer, which indicates how many digits of the (IS-formatted) date were known.
|2010||4||We know the year exactly, so we know the first 4 digits|
|January 2010||6||Month and year|
|1 January 2010||8||Day, month and year|
