re3data caters to a range of needs for diverse stakeholders (Vierkant et al., 2021). Detailed and precise repository descriptions are at the heart of the majority of these use cases, and repository metadata are given special attention at the re3data registry.

Collaboration has always been a central principle for re3data. This is reflected in the fact that research communities, repository providers, and other relevant stakeholders contribute significantly to the completeness and accuracy of the re3data metadata as well as its further technical and conceptual development.

Currently, re3data offers unrestricted access to comprehensive descriptions of more than 3100 research data repositories from all disciplines and all regions. The repository descriptions are based on the re3data Metadata Schema.

The objective of the workshop was to approach the pervasive, yet elusive topic of data quality management from several angles. To ensure a common frame of reference for the workshop, contributions were guided by the Framework for Quality Assurance of Data Publications at Research Data Repositories that was developed as part of a PhD project.

In this post, the authors celebrate the 10th anniversary of re3data, sharing insights about the history, the service itself, and how it has developed over the last decade. The post was published simultaneously on the DataCite Blog. The re3data registry went online in 2012 and is celebrating a decade of curation and making information about data repositories available to the research community.

Data quality assurance is a fundamental issue for repositories that seek to ensure trust in their services. This workshop focused on measures research data repositories undertake to ensure data quality. The objective of this workshop was to raise awareness and make the various activities repositories perform to assure, assess, and improve data quality visible.

International collaboration has become very common in the production of scientific knowledge (Coccia and Wang, 2016; Monastersky &

Openness may sound self-evident, but in fact it can mean different things, even within the Open Science community (Pasquetto, Sands & Borgman, 2015). To align understanding and to ensure common goals in the transition to Open Science, clear definitions are needed.

When looking for a suitable repository, the discipline(s) a repository caters to is one of the most important pieces of information. The re3data Metadata Schema reflects this priority by requiring the element subject for all indexed repositories. However, describing the disciplinary focus of research data repositories is not an easy task.

To keep track of where you are going, you need to check your compass from time to time. For this purpose, the re3data COREF project undertook a series of workshops in 2020 and have now come up with a new Conceptual Model for User Stories for the Registry of Research Data Repositories – re3data. We are grateful to welcome you along this journey and share our results with you.
