Open Event Data Manifesto

Open Event Da­ta Ma­ni­festo

Events play an important role in the public life of a society. Timely provision of accurate information about upcoming events to potential target audiences plays a key role in bringing people together for purposeful activities. Ensuring the visibility of events and availability of event data in the digital space has therefore become a major preoccupation of producers and organizers of events in the digital age.

There are a variety of initiatives to pool event data on central data platforms, such as event calendars, tourism platforms, cultural agendas, sports agendas, ticketing platforms and the like. While the integration of this data still involves manual effort in many cases, various stakeholders have recognized the potential that lies in automatizing the data transfer and in establishing a culture of sharing in order to facilitate the dissemina- tion of event data.

At the heart of our mission is the Open Event Data Manifesto, which guides our work. This manifesto sets out the basic principles for our activities, highlighting the importance of making event data openly available to everyone. In the coming months, we will create an action plan based on the manifesto’s principles to ensure that the power of open data drives our efforts.
