Comprehensive DRS Implementation

Everything you need to understand and implement the GA4GH DRS specification

Full DRS v1.2 API

Complete implementation of all DRS v1.2 endpoints: service-info, get object, list objects, and access URL generation.

Objects & Bundles

Demonstrates both individual objects and hierarchical bundles with expand parameter support for nested contents.

Multiple Checksums

MD5 and SHA-256 checksums for all objects to ensure data integrity and verification after download.

Access Methods

Multiple access methods (HTTPS, S3, etc.) with signed URL generation for secure, time-limited access.

Authentication Ready

Support for both public and authenticated access patterns using Laravel Sanctum for API token authentication.

Real Datasets

Realistic genomic neuroscience datasets: fMRI scans, whole genome sequencing, RNA-seq, EEG recordings, and more.
