Digital CityLab is a new website that has transferred the CityLab concept to a digital platform for users. The user space is a digital map of the city on which places can be marked and expanded with the stories and knowledge of Frankfurters. The users can tell their stories digitally with video and audio contributions, photos and texts. It’s all about collecting experiences, personal stories, special relationships to particular places, different ways of using the city together and about data that opens up to new perspectives. The focus is on depicting polyphony: the plan is to build an audio-visual, multi-perspective and ever-changing city portrait shaped by user contributions. This means that the museum will be collecting digital objects together with users as testimonies to Frankfurt’s present – both “live” and online. The museum selects changing contributions from the growing collection, which will be shown at media stations in the museum. The Digital CityLab sees itself as a methodical experiment, a platform and digital interaction space – a virtual place for the museum to actively interact with its users and its city.
