Tatin Test Registry

Usage data

You may publish any packages to the Tatin Test Registry with the API key "Tatin-Test-API-Key" except for the groups "dyalog" and "aplteam". However, note that the data of the Test Registry is occasionally reset.

Via this page you can download usage data for packages.

For every year there is a file usage-data-<YYYY>.zip (if data is available)
For the current year there is a file usage-data-<YYYY>-<MM>.zip which means you get all data from this year except the current month

The following steps are carried out by any Tatin Server:

On the first of January of any given year:

All the data of the pevious year is collected and saved in usage-data-<YYYY>.csv
A file usage-data-<YYYY>.zip is created from that CSV file

On the first day of any given month (except the first of January):

A file usage-data-<YYYY>-<MM>.csv is created the comprehends all the data of that year except the new month
A file usage-data-<YYYY>-<MM>.zip is created from that CSV file

The table shows the data from the file "usage-data-2025-05.csv" but aggregated by month and version number.

Because of the aggregation, "Month" and "Year" are no longer meaningful, therefore these columns are not shown.
