META-BASE

META-BASE integrates genomic metadata from diverse public repositories into the Genomic Data Model format to harmonize heterogeneous datasets for biological and clinical research.

Key Features:

• Structured Transformation Process: Extracts, cleans, normalizes, and enriches metadata from genomic data sources.
• Repository Support: Integrates metadata from Encode, TCGA (The Cancer Genome Atlas), Roadmap Epigenomics, 1000 Genomes, and other public repositories.
• Data Model Standardization: Converts and harmonizes metadata into the Genomic Data Model format.
• Ontology and Vocabulary Harmonization: Reconciles differing metadata definitions, vocabularies, and ontologies across repositories.
• Extensible Pipeline: Provides a general, open, extensible pipeline capable of incorporating new data sources without major architectural changes.
• Integration of Heterogeneous Datasets: Combines disparate datasets to reduce errors and manual effort associated with accessing multiple repositories.

Scientific Applications:

• Cross-repository metadata integration: Enables combined analyses across Encode, TCGA, Roadmap Epigenomics, 1000 Genomes, and other datasets.
• Support for biological and clinical research: Provides harmonized metadata that facilitates downstream biological and clinical analyses.
• Metadata quality improvement: Improves consistency and completeness of metadata through extraction, cleaning, normalization, and enrichment.

Methodology:

Applies a structured transformation process that extracts, cleans, normalizes, and enriches metadata and standardizes integration into the Genomic Data Model via an open, extensible pipeline capable of incorporating new data sources.
