Federated Metadata Discovery and Analysis Functional Profile
There are numerous data repositories on the web today. These data repositories contain essential information that must be accessible to services in the ecosystem. As a result, caGrid 2.0 must provide capabilities to integrate these external repositories into the grid with the assumption that the remote service cannot be changed.
The semantic infrastructure will support integration with other metadata repositories, allowing the platform to leverage the semantic infrastructure for federated metadata discovery and analysis. The federated data query capabilities will be implemented by the platform.
This Functional Profile includes, but is not limited to, the following capability elaborations:
Derived From Requirements
- Gap Analysis::Federation::084 - Localize Metadata Maintenance Federate the metadata infrastructure such that different organizations, departments, labs, software applications, etc. can maintain their own metadata while standards flow both top-down and bottom-up. The current semantic infrastructure at NCI is not amenable to this type of federated model.
- Semantic Infrastructure Requirements::caGRID 2.0 Platform and Terminology Integration::External Data Repositories There are numerous data repositories on the web today. These data repositories contain essential information that must be accessible to services in the ecosystem. As a result, caGrid 2.0 must provide capabilities to integrate these external repositories into the grid with the assumption that the remote service cannot be changed. The semantic infrastructure will support integration with other metadata repositories, allowing the platform to leverage the semantic infrastructure for federated metadata discovery and analysis. The federated data query capabilities will be implemented by the platform. Link to use case satisfied from caGRID 2.0 roadmap: The oncologist searches both TCGA glioblastoma data as well as de-identified data that has been added by care providers around the country. The additional data sets are external data repositories.
externalMetadataRepositoryIntegration
The semantic infrastructure will support integration with other metadata repositories, allowing the platform to leverage the semantic infrastructure for federated metadata discovery and analysis. The federated data query capabilities will be implemented by the platform.
localizeMetadataMaintenance
Federate the metadata infrastructure such that different organizations, departments, labs, software applications, etc. can maintain their own metadata while standards flow both topdown and bottom-up. The current semantic infrastructure at NCI is not amenable to this type of federated model.
