DDI Developers Hackathon - Registration and Submission of Challenges now open

Dear all

As you might know from our previous Save-the-Date Mail and the invitation at the EDDI Conference in December 2022, we plan to revive the DDI Developers Group which has been dormant since 2014 by organizing a DDI Developers Hackathon at the facilities of the Swedish National Data Service in Gothenburg (Medicinaregatan 18A) from Friday 24th of March until Saturday 25th of March, 2023. In the meantime we finalized the agenda (listed below) and can finally open the registration and submission of challenges for this event. This event is directly following the Research Data Alliance (RDA) plenary in the same week. Therefore we believe some participants could already be at the location saving travel costs.

If you are 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.

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, 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. As special as all three organizers are craft brewers we will also provide two craft beers especially brewed for this event. All catering will be free of cost.

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.

We hope to re-create some lasting interest for more IT-related topics within the DDI community. Therefore we are happy for every developer, software engineer, programmer or DevOps person who can make it to Gothenburg.

Best Regards
