IRIDA is designed to act similar to a “federated” database system. This allows sequencing centres to store and analyze their own data locally while being able to contribute their results to a larger global context. This decentralized model is preferred as it reduces the infrastructure requirements of major sequencing centres and allows smaller centres to work more independently.
IRIDA’s data sharing system works by synchronizing data between IRIDA installations. It allows IRIDA administrators to link up their IRIDA systems over the internet and automatically pull project data, sequencing data, and metadata between them. This allows users over multiple IRIDA installations to analyze the same datasets for larger research projects or outbreaks.

IRIDA data sharing solutions:
- Permission Control – authentication /authorization for information sharing
- User role-based display of information
There are often many different investigators, analysts, agencies and other stakeholders involved in infectious disease surveillance and outbreak response. Not only can information sharing during investigations be inefficient and ad hoc, but often data must be recoded and/or reentered into different reporting systems.
IRIDA’s federated data management system enables autonomous instances to connect and share their projects, samples and analyses through IRIDA’s User Profile System (OAuth2 framework). User role permissions control visibility and editing of content. Sample data and results can be shared between IRIDA instances simply by changing user profile permissions, which can be customized according to data governance guidelines, bypassing the need to transmit sensitive information by fax, phone, mail or email. Changing of permissions is permitted transiently or permanently by instance administrators, who can manage their User Groups in such a way as to alter single profiles or assign bulk permissions. Federated access allows labs and health authorities to maintain ownership and control over their own data, thereby protecting patient privacy while performing analyses.
Currently, data sharing primarily occurs between instances employed by PulseNet – Canada.
