17th EDDI Conference

When: December 1–5, 2025
Where: Budapest
Registration: Early bird until November 19

At the beginning of December, the DDI Alliance (in collaboration with CESSDA and ELTE Centre for Social Sciences) will hold its regular annual conference of European users of the DDI metadata standard, the “17th European DDI Users Conference“.

The conference topics will cover the role of DDI in supporting FAIR principles, long-term data archiving, and improving interoperability between research infrastructures and the data stored in them. The event is an ideal platform for sharing experiences and addressing specific challenges.

The conference will focus on presenting real-world use cases and the practical application of the DDI standard. The program will offer workshops for beginners, including “Introduction to DDI for Small Organizations“, which will introduce the basics of DDI implementation even with limited resources. For example, the Colectica system will be presented.

The conference will also present the DDI-CDI specification, published in spring 2025, which extends classic DDI with the ability to link heterogeneous data across scientific domains (e.g., social sciences, biomedicine, sensor data). DDI-CDI allows you to describe relationships between diverse sources (both structured and unstructured) and create complex data models. It is key to interdisciplinary research and big data analysis. The DDI-CDI specification version 1.0 is publicly available on the DDI Alliance website. The program also includes a presentation of the planned ISO certification of DDI, examples of the use of DDI-Lifecycle, DDI Codebook, ELSST, and much more.

More details about the conference can be found here, and the complete program is available here.

Registration is possible here.

About DDI (Data Documentation Initiative)

DDI is an international standard for research data documentation. It describes the structure of data (variables, codes, questionnaires), collection methodology, research context, and data lifecycle management through a series of modules. It primarily concerns quantitative data (surveys, administrative records, experiments).
