We're building a future where data is connected, reusable, and rooted in history, allowing us to study humanity at an unprecedented scale. Help us realize this by contributing your research data today!


datalegend is a joint initiative of the International Institute of Social History, the Vrije Universiteit Amsterdam, and Utrecht University, as part of the larger CLARIAH project, funded by the Netherlands Organisation for Scientific Research (NWO).

It's easy

A fast, responsive interface allows you to set your data free. A community effort to connect data and codes, by and for researchers.

Once published on datalegend, your data is directly available for query-based analysis and comparative, cross-dataset studies.

You're in control of who can access your data.

The Shoulders of Giants

Grow a web of interconnected, provenance-aware, structured data. Formulate and share live queries across the research data web, and directly link to them from your research publication. Build apps and visualizations that make your data come alive.



Bring your data to life

Publishing your data with datalegend makes it into a hub within a growing network of interconnected, live accessible data.

Save time

Studies show that in data-based scientific workflows, 60% of time is spent on data cleaning and data harmonization. datalegend allows you to focus on research and research alone.

Know your data better

In datalegend, your data is more easily analysed, and compareable to other data. Your research questions can be posed against and across multiple datasets in one go.
