Data Catalog and Discovery¶
Unified data cataloging, discovery, and governance powered by OpenMetadata and AWS data services.
Overview¶
RosettaHub integrates with OpenMetadata and AWS data services to provide a complete data management layer alongside compute orchestration. Researchers can discover datasets, understand data quality and lineage, and launch pre-configured environments to analyze data -- all from within the platform.
OpenMetadata Integration¶
OpenMetadata is an end-to-end open source metadata platform providing data catalog, discovery, data quality, governance, collaboration, and lineage capabilities.
Integration Architecture¶
RosettaHub provides deep integration with OpenMetadata:
| Capability | Description |
|---|---|
| SSO via Keycloak | Researchers sign in to OpenMetadata with their institutional identity -- no separate credentials |
| Role propagation | RosettaHub organization roles (admin, manager, user) map to OpenMetadata roles automatically |
| Datasets as cloud model artifacts | Datasets cataloged in OpenMetadata appear as first-class artifacts in the RosettaHub cloud model |
| Access control | Dataset access permissions are managed from within RosettaHub and enforced in OpenMetadata |
What OpenMetadata Provides¶
- Data catalog -- browse and search all datasets across the organization
- Data discovery -- find relevant datasets by topic, tag, owner, or schema
- Data quality -- define and monitor quality rules, track data freshness
- Data lineage -- visualize how data flows from source to analysis
- Collaboration -- comment on datasets, request access, share knowledge
- Governance -- classify data sensitivity, enforce retention policies
Timeline
OpenMetadata integration is production-ready in early April 2026.
AWS Data Integrations¶
RosettaHub integrates with AWS data services to bring external datasets into the platform:
AWS Data Exchange¶
Deep integration with AWS Data Exchange enables:
| Capability | Description |
|---|---|
| Mirror public datasets | All public datasets available through ADX are mirrored to a dedicated RosettaHub marketplace |
| Auto-map acquired datasets | Datasets acquired via ADX are automatically mapped to RosettaHub artifacts |
| One-click environments | Launch Formations pre-configured to visualize and analyze specific datasets |
Additional AWS Data Services¶
| Service | Integration |
|---|---|
| Amazon DataZone | Metadata domains and data products integrated with RosettaHub catalog |
| Amazon SageMaker Catalog | ML model and dataset catalog accessible from RosettaHub |
| AWS Lake Formation | Fine-grained data access controls and data lineage |
| AWS Registry of Open Data | Public research datasets (Sentinel-2, Landsat, ERA5, NOAA) available as pre-mounted storages |
Data + Compute Bundles¶
One of RosettaHub's unique capabilities is bundling data access with compute environments:
- Catalog a dataset in OpenMetadata (or acquire via AWS Data Exchange)
- Create a Formation that pre-mounts the dataset as a Storage
- Publish to the marketplace -- researchers browse and launch with one click
- Access controls apply -- only researchers with the right project membership and data tier can access the formation
This eliminates the gap between "finding data" and "analyzing data" that exists in most research environments.
Private Marketplace¶
Institutions can build private marketplaces of data-configured environments:
- Institutional data catalogs -- curated datasets relevant to the organization
- Pre-mounted storages -- S3 buckets, EFS file systems, or cross-cloud storage attached to formations
- URL-based sharing -- share data-configured environments via link
- Folder-level S3 mapping -- different teams see scoped views of the same underlying bucket
