When: December 1–5, 2025
Where: Budapest, Hungary

The 17th European DDI Conference (EDDI 2025) will take place from December 1 to 5, 2025, in Budapest, Hungary. The event is organized by the Research Documentation Centre at the HUN-REN Centre for Social Sciences. This international conference is the largest European gathering of professionals and users working with the Data Documentation Initiative (DDI) standard.

DDI is an international standard for the structured description of data collected through surveys and other observational methods, mainly in the social, behavioral, economic, and health sciences. It helps make data more understandable, easily shareable, and reusable, aligning with the FAIR principles and open science goals. By providing a common language and format for metadata, DDI enhances interoperability, improves data quality, and promotes transparency in research.

The conference program includes hands-on tutorials and workshops on December 1, followed by the main two-day conference on December 2–3, and additional side meetings on December 4–5. The event will bring together researchers, data specialists, developers, and representatives from institutions across Europe and beyond. Participation is open to anyone involved in the development, application, critical assessment, or use of DDI, both inside and outside academia.

The organizers invite submissions on all topics related to DDI. Contributions may include case studies, practical experiences, early-stage projects, integration of DDI with other technologies, critical evaluations, or community-building activities supporting DDI users and professionals.

The conference covers a wide range of topics, including but not limited to:

• – Capacity building and support for smaller organizations
• – User needs and the development of efficient data infrastructures
• – Applications of DDI in official statistics
• – Metadata sharing and reuse
• – Data and metadata harmonization
• – Encouraging research data documentation
• – DDI in the context of open data and Linked Open Data
• – Ethical issues concerning data and metadata
• – Use of artificial intelligence, machine learning, and automation in metadata management
• – Development and deployment of software and tools supporting the DDI standard

Submissions can take various forms, such as discussion sessions, short or full presentations, posters, workshops, or side meetings.

The deadline for submitting proposals is September 1, 2025, at 23:59 CEST. Conference registration will open on September 26, 2025.
