AncientMetagenomeDir

AncientMetagenomeDir curates standardized metadata for published shotgun-sequenced ancient metagenomes and microbial genome-level enriched samples to support reproducible analyses and meta-analyses in ancient metagenomics.

Key Features:

• Community-Curated Metadata Repository: Aggregates annotated lists of metagenomic samples from published studies with standardized metadata and accession numbers for sequence-read archives.
• Standardization and Interoperability: Applies internal guidelines and automated checks to ensure metadata compatibility with sequence-read archives and term ontologies.
• Breadth and Consensus: Covers multiple sub-disciplines within ancient metagenomics to provide consensus metadata definitions across diverse sample types.
• Facilitation of Large-Scale Studies: Provides standardized metadata enabling analysis of microbial and eukaryotic taxa and communities across temporal and spatial scales.
• Assistance in Future Research Standardization: Establishes precedent for metadata reporting to promote consistent dataset deposition and downstream integrative analyses.

Scientific Applications:

• Meta-analyses of ancient microbial communities: Enables integration of shotgun-sequenced datasets and enriched microbial genome samples for comparative meta-analyses across studies.
• Reconstruction of past ecosystems and ecological interactions: Supports ecological and paleoecological studies of biodiversity and community dynamics in ancient environments.
• Evolutionary and taxon-specific investigations: Facilitates comparative analyses of microbes and eukaryotes to investigate evolutionary trajectories across temporal contexts.

Methodology:

Community curation of metadata from published studies, standardization according to internal guidelines, and automated checks for compliance with sequence-read archive standards and term ontologies.
