DDI Developers Hackathon 2024 - Registration and Submission of Challenges now open

After the success of last years DDI Developers Hackathon in Gothenburg we would like to announce the second round for 2024.

This year we will be at the facilities of GESIS in Cologne (Unter Sachsenhausen 6-8) from Friday 10th of May until Saturday 12th of May, 2024. Please find included the agenda as a PDF as well as the registration and submission of challenges for this year's event. We also connected the event to a long weekend in most countries of Europe to make travelling for many people more convenient.

If you are already a member of the DDI Developers group we would be happy if you could also join this year.

If you are generally a developer, software engineer or programmer using or implementing tools around the DDI suite of metadata standards this event might be the chance to exchange ideas with similar people plus during the two days we would like to create some prototypical software implementations of current pain points or needed features for DDI tools. Also, you might consider to join our steadily growing community.

If you are engaged in DDI related work (e.g. in working groups or any of the boards) you are welcome to submit challenges (i.e. implementation ideas) for the participating hackers, even if you do not participate in person.

The event is sponsored by the DDI Alliance, GESIS - the Leibniz Institute of Social Sciences, the Swedish National Data Service (SND) and the University of Applied Sciences of the Grisons (FHGR) which will provide catering and the location for the whole event. For a limited number of people also sponsorships for travel costs can be provided if the member organizations cannot sponsor it.

Please register here for the Hackathon


Please submit ideas for topics (so called challenges) for the participating hackers here


During the event there will be a Hackathon Bar which provides snacks and drinks for the participating hackers at all times. Additionally there will be lunch and dinner served at fitting times during the implementation phases so hackers can fully concentrate on their tasks. The event will also start with a welcome dinner on Thursday evening and end with a thank you dinner on Saturday evening.

The results from the Hackathon will be available as Open Source software under a license (e.g. MIT, LGPL) which will allow the use in other Open Source projects as well as commercial products.

As the first Hackathon in Gothenburg last year led to highly interesting implementation ideas and synergies between developers we hope to re-create the same atmosphere this year also in Cologne. Therefore we hope to see you soon.
