As the tourism marketing agency for the State of Berlin, visitBerlin manages the capital’s largest calendar of events. visitBerlin has now succeeded in bringing together this event data with a wealth of tourism-related information – such as hotels, attractions and much more – in a single data hub.
werk21 was tasked with importing events from the data hub into the existing Drupal system. Working within an agile project framework, werk21 supported the visitBerlin team in implementing the necessary data structure. The main challenge lay in consolidating events from various sources into a uniform data structure and mapping these to the existing events within the Drupal system. In particular, the more precise time specifications – which now allow for data down to the day and also recurrence cycles for each event – represent significant added value for the user, but posed major challenges during implementation.
The data hub integration was successfully launched in March 2026. Thanks to this new integration, events can now be found more accurately in the calendar, and thanks to Schema.org markup, they are also optimised for search engines. By integrating external sources, we have not only improved the quality of the events but also added more than 10,000 new entries.
