SnoVault

SnoVault manages and organizes experimental metadata and associated files to support cataloging functional genomic elements across cell lines and tissues for projects such as ENCODE.

Key Features:

• Metadata and file submission: Accepts and records experimental metadata and associated files to ensure structured capture of assay and sample information.
• Database storage: Provides a database infrastructure for storing extensive metadata to enable organization and retrieval.
• API for querying metadata: Exposes a robust API for programmatic querying and extraction of metadata.
• Core database engine (SnoVault): Implements the backend as a reusable Python-based database engine independent of ENCODE-specific data.

Scientific Applications:

• ENCODE project support: Manages and organizes metadata for the ENCODE Data Coordination Center to support the cataloging of genomic elements.
• Cataloging functional genomic elements: Enables aggregation of assay and sample metadata across cell lines and tissues to facilitate identification of functional elements.
• Large-scale genomic research: Supports metadata management for large, multi-assay genomic projects and other bioinformatics contexts.

Methodology:

Metadata and file submission, storage in the SnoVault database engine implemented as a Python package, and access via a robust API for querying.
