Happy holidays and a healthy New Year 2026

The year 2025 is slowly drawing to a close, and we would like to take this opportunity to look back with you on the important events of the past twelve months.

2025 was dominated by the major topic of the future proportional financing of DeepGreen by the participating institutions. With the first concrete proposal for a financing model, we approached you in the middle of the year to incorporate your views into our plans. An important result was a number of constructive suggestions on how we could improve the financing model. While we continue to work on this, at the end of 2025 the KOBV Curatorium decided that DeepGreen will continue to be financed from the partner institutions’ own funds in 2026. Information on the revised cost model will follow in 2026.

With regard to the technical infrastructure, we were able to implement a number of further developments in collaboration with Cottage Labs. For example, name variations can now be excluded in the affiliations file repositories. In addition, important updates that were essential for the stability and maintainability of the service were completed: DeepGreen was updated to a new Python version and moved to a new server infrastructure, and a new sFTP for publisher data and the Airflow process management tool were implemented.

We are delighted that DeepGreen continued to grow in 2025. At the beginning of the year, a cooperation agreement was signed with the publisher Duncker & Humblot. In addition, four institutional repositories decided to use DeepGreen. As of December 15, 2025, we were able to make a total of 109,439 articles available to our repositories.

Finally, we would like to thank all repositories, publishers, and cooperation partners for their interest and excellent collaboration. At the same time, we look forward to an exciting 2026, which we want to shape together with you.
