Analysis export data files with wrong fields

Where to find the issue

https://www.coronawarn.app/en/analysis/ “Corona-Warn-App (CWA): Key performance indicators” using files published to:

1. https://obs.eu-de.otc.t-systems.com/obs-public-dashboard/csv/cwa_all_data.zip
2. https://obs.eu-de.otc.t-systems.com/obs-public-dashboard/csv/cwa_downloads_data.zip
3. https://obs.eu-de.otc.t-systems.com/obs-public-dashboard/csv/test_results_data.zip
4. https://obs.eu-de.otc.t-systems.com/obs-public-dashboard/csv/cwa_sharing_data.zip
5. https://obs.eu-de.otc.t-systems.com/obs-public-dashboard/csv/cwa_ppa_warnings_data.zip

This issue concerns files with the embedded filename date 2021-12-02 i.e. CWA_dashboard_data_2021-12-02.csv. The files are replaced daily, so it is unknown if the error is temporary or persistent.

Describe the issue

The csv files associated with “Export data” graphs on the Corona-Warn-App (CWA): Key performance indicators page contain incorrect data fields.

1. All files contain the field infections_published_daily which is not displayed anywhere on the Analysis page.
2. The Downloads file cwa_downloads_data.zip contains no downloads fields and contains instead ppa fields.
3. The PPA file cwa_ppa_warnings_data.zip is missing the fields update_timestamp and effective_date. It contains also fields from downloads and test sharing.

Steps to reproduce

1. Open https://www.coronawarn.app/en/analysis/ in a web browser
2. Click “Export all Data”
3. For each graph: click the “Export” link, then “Export data” to download a zip file.
4. Extract the contents of each downloaded zip file
5. Examine the first line of each CWA_dashboard_data_YYYY-MM-DD.csv file which contains the field names
6. Compare with the names according to the document CWA_dashboard_data-en.pdf

Suggested change

Concerning the csv files in the zip files:

1. Remove the field infections_published_daily from all csv files.
2. Correct the Downloads file cwa_downloads_data.zip so it contains only downloads data and no other fields.
3. Correct the PPA file cwa_ppa_warnings_data.zip to include the fields update_timestamp and effective_date. Remove the fields from downloads and test sharing.

@HelTob Thanks for the feedback about your planned documentation update. It is good to hear that you plan to add a field definition.

I don’t think we need to track this point separately here, so I will now close this issue.

Thanks again to @dsarkar and to you!
