Our Membership
iRODS is
- Open Source
- Distributed
- Data Centric
- Metadata Driven
A flexible framework for the abstraction of infrastructure
iRODS as the Integration Layer
iRODS Core Competencies
The underlying technology categorized into four areas
Data Virtualization
Combine various distributed storage technologies into a Unified Namespace
- Existing file systems
- Cloud storage
- On premises object storage
- Archival storage systems
iRODS provides a logical view into the complex physical representation of your data, distributed geographically, and at scale.
Projection of the Physical into the Logical
Logical Path
Physical Path(s)
Data Discovery
Attach metadata to any first class entity within the iRODS Zone
- Data Objects
- Collections
- Users
- Storage Resources
- The Namespace
iRODS provides automated and user-provided metadata which makes your data and infrastructure more discoverable, operational and valuable.
Metadata Everywhere
Workflow Automation
Integrated scripting language which is triggered by any operation within the framework
- Authentication
- Storage Access
- Database Interaction
- Network Activity
- Extensible RPC API
The iRODS rule engine provides the ability to capture real world policy as computer actionable rules which may allow, deny, or add context to operations within the system.
Dynamic Policy Enforcement
- restrict access
- log for audit and reporting
- provide additional context
- send a notification
The iRODS rule may:
Dynamic Policy Enforcement
A single API call expands to many plugin operations all of which may invoke policy enforcement
- Authentication
- Database
- Storage
- Network
- Rule Engine
- Microservice
- RPC API
Plugin Interfaces:
Secure Collaboration
iRODS allows for collaboration across administrative boundaries after deployment
- No need for common infrastructure
- No need for shared funding
- Affords temporary collaborations
iRODS provides the ability to federate namespaces across organizations without pre-coordinated funding or effort.
iRODS as a Service Interface
Federation - Shared Data and Services
Ingest to Institutional repository
As data matures and reaches a broader community, data management policy must also evolve to meet these additional requirements.
iRODS Capabilities

Use Cases
iRODS
The Wellcome Sanger Institute
Sanger - Replication
- Data preferentially placed on resource servers in the green data center (fallback to red)
- Data replicated to the other room.
- Checksums applied
- Green and red centers both used for read access.

Sanger - Federation
University College London
- UK sponsored research requirements: last date of access request plus 10 years
- iRODS tiers data across storage technologies
- Enables federated access from other centers
