The BioLink project was set up for a threefold purpose: 1. To assess existing biobanks’ and registries’ willingness to link and share data; 2. To set up demonstration projects, identifying pitfalls and stumbling blocks in complex linkage projects; 3. To develop a standardized method of sharing data across registries and institutes, that would enable faster data access without compromising legal or ethical considerations. The project has yielded several publications, which can be found on biolink-nl.eu.
