LaminDB - Open-Source Biomedical Data Lake Management System

Overview of Capabilities

LaminDB is an open-source, lineage-based biomedical data lake platform designed for biomedical research. It makes datasets and models queryable, traceable, verifiable, and compliant with the FAIR principles. It supports a wide range of biological data formats, including single-cell sequencing, spatial transcriptomics, and flow cytometry.

Use Cases

1. Single-Cell RNA Sequencing Analysis and Management

Designed to process and analyze single-cell RNA sequencing data. It supports data validation, standardization, and quality control for formats such as AnnData. By using a built-in cell type ontology, it automatically standardizes cell-type annotations, enabling cross-batch and cross-experiment data integration and comparative analyses.

2. Biomedical Data Lineage Tracking and Validation

For biomedical research that requires strict data traceability, LaminDB automatically records data processing workflows, input-output relationships, parameter settings, and the computational environment. It supports end-to-end lineage tracking from raw data to final results, ensuring the reproducibility and verifiability of research findings and aligning with best practices in research data management.

3. Multi-Omics Data Integration and Collaborative Research

Provides research teams with a unified data management platform. It supports the integrated storage and querying of multi-omics data such as genomics, transcriptomics, and proteomics. Through cloud storage integration and access control, it enables data sharing, collaborative annotation, and version control among team members, improving research efficiency.

Core Features

1. Data Querying and Lineage Tracking

Offers powerful data query interfaces that support filtering and searching biological datasets across multiple dimensions such as features, time, and creators. It automatically tracks data processing workflows, recording each dataset’s source, transformation history, and the code and parameters used. Visual lineage graphs help researchers understand the data flow path, ensuring processes are traceable and reproducible.

2. Biological Data Validation and Standardization

Supports validation for multiple biological data formats including DataFrame, AnnData, SpatialData, TileDB-SOMA, Parquet, and Zarr. By defining data schemas, it automatically checks the validity of data structures and values, identifying and flagging quality issues. It also provides standardization tools that automatically fix common errors and map synonyms to standardized terms, ensuring data quality meets analysis requirements.

3. Ontology-Driven Annotation System

Integrates the Bionty biological ontology library, covering multiple public ontologies such as genes (Ensembl), proteins (UniProt), cell types (CL), tissues (Uberon), diseases (Mondo), and phenotypes (HPO). It supports ontology import, search, and hierarchical browsing, enabling standardized annotation of biological entities. It also allows creation of custom ontologies and terminology systems to meet annotation needs for specific research projects.
