The platform “Berlin Big City Stories” presents Berlin-related digitized stories and memorabilia from users - together with content from archives, libraries and museums. These are published as open data under a free license (CC0 or CC-BY-SA) for subsequent use by third parties on the platform.

The platform was implemented as part of the project "100 Years of Big City Stories Berlin: Berlin Views of the 20th Century" in 2014 and 2015 on the basis of the open source software Omeka in cooperation with the company Culture To Go and in 2016 with  Culture To Go (conception & programming) and place / making (design) further developed.

Stories contain narrative user contributions with information on authors, chronological and content-related classification, copyright information, etc., with which the associated media objects are linked. In addition, a story can be linked to locations . In addition, stories can provide media files that can serve as story-specific preview images.

Media objects are the objects that provide the media files - be it image or text files, audio files or references to video offers (by embedding Youtube / Vimeo code). Media objects also contain information about their creation, chronological and content-related classification, copyright information, etc. Through the link with stories , media objects can be assigned to locations . However, media objects can also be linked directly to locations .

Places are the geographical units of the platform. In addition to the name of the place, they contain general address information and geographic coordinates. Stories and media objects can be linked to places .
