Summary
FRED is a new toolkit that simplifies FAIR metadata management for omics research. It ensures standardized, searchable metadata, improving data sharing and scientific discovery.
Area of Science:
- Bioinformatics
- Data Science
- Genomics
Background:
- Scientific data sharing requires transparent dissemination of raw data, metadata, and experimental details.
- Research Data Management (RDM) is crucial for scientific discovery and FAIR principles, but metadata standardization remains a challenge.
- Current practices often lack standardized metadata, hindering effective data utilization and sharing.
Purpose of the Study:
- To present FRED, a generalized toolkit for FAIR metadata management in omics research.
- To enable guided metadata creation, structured validation, and cross-file searching.
- To facilitate integration with existing RDM infrastructure and external systems.
Main Methods:
- FRED utilizes a flexible, machine-readable YAML format for metadata.
- It offers guided, dialog-based creation of metadata files.
- Features include semantic validation, logical cross-file search, API integration, and self-hosted deployment.
Main Results:
- A complete annotation workflow for a single-nucleus RNA-seq dataset was demonstrated using FRED.
- The workflow covered metadata generation, validation, repository-based discovery, and export to NCBI GEO format.
- FRED successfully integrated into existing RDM infrastructure without requiring dedicated IT resources.
Conclusions:
- FRED provides a generalized solution for FAIR metadata management in omics research.
- The toolkit is designed for accessibility by non-computational scientists and specialized facilities.
- FRED enhances data sharing, utilization, and reproducibility in scientific research.
