daten.berlin.de Usage Statistics

This dataset contains usage statistics (page impressions and visits) for the Berlin Open Data Portal https://daten.berlin.de. Statistics are collected per month, both for the domain as a whole, and for all individual datasets (pages below /datensaetze).

Statistics are given in both CSV (domain totals only) and JSON (one combined file).

Starting with the 2025-07 data, we have introduced several changes:

• We stopped using the deprecated JSON-RPC-API and are now using the Mapp Analytics API.
• We have replaced the old Ruby code with Python code.
• We have stopped generating the per-dataset-CSV file, because it became too big and unwieldy (the last version from 2025-06 had 155 columns). All data is included in the combined JSON file: daten_berlin_de.stats.json.

Until 2019-12-31, usage statistics were collected with our internal BerlinOnline Site Statistics (BOSS) tool. As of 2020-01-01 we have stopped using BOSS on the Berlin Open Data Portal, and have replaced it with Mapp Analytics. Mapp (formerly Webtrekk) has been in use since February 2019. While BOSS and Mapp provide the same metrics, the actual results differ. We have written a little bit on how and possible why BOSS and Mapp differ with respect to their results.

The historic BOSS data has been moved to data/historical, while the current Mapp data resides in data/current.

Requirements

The code to extract the usage statistics is written in Python. It has been tested with Python 3.13.

The required libraries are defined in data-requirements.txt. In particular, these are:

• python-dateutil
• requests
• keyring (only if you're running this on Mac OS and have the Mapp PW stored in your keychain)

Normalization of Dataset Names

In August 2024, the Open Data Portal received a major update, which resulted in slightly changed URLs for many datasets. There is a mapping from the old to the new datasets: https://github.com/berlinonline/berlin_dataset_name_mapping

Starting in November 2024, the dataset names in the usage statistics have been normalized to show the new dataset names everywhere, to allow comparisons through time.

In cases where requests to both the old and the new name were made in the same month, both have been combined to a single entry, with the sum of the impressions and visits. This normalization is implemented in the map_dataset_names.py script.

For example, there is the following mapping:

old_name,new_name
verlauf-der-berliner-mauer-1989-wms,verlauf-der-berliner-mauer-1989-wms-bc24fb23

In the usage data, there is:

...
    "2024-10": {
      "verlauf-der-berliner-mauer-1989-wms-bc24fb23": {
        "impressions": 247,
        "visits": 210
      },
      ...
      "verlauf-der-berliner-mauer-1989-wms": {
        "impressions": 1,
        "visits": 1
      },
...

These two entries have been combined to:

...
    "2024-10": {
      "verlauf-der-berliner-mauer-1989-wms-bc24fb23": {
        "impressions": 248,
        "visits": 211
      },
...
