Principles of service provision


Our data and tools are freely available, without restriction. The only exception is potentially identifiable human genetic information, for which access depends on research consent agreements.


EMBL-EBI is a world leader in the development of global bioinformatics standards, which are key to data sharing.


Thanks to our many data-sharing agreements, EMBL-EBI resources are comprehensive and up to date. We work with publishers to ensure that biological data must be placed in a public repository and cross-referenced in the relevant publication.


All of our data and many of our software systems can be downloaded and installed locally.

High quality

Our data resources are enhanced through annotation: highly qualified biologists add value to data resources by incorporating features of genes or proteins from other sources, and automated annotation is subjected to rigorous quality control.
