OLS4
Provides a central repository for biomedical ontologies, offering a single point of access to their latest versions.
The Ontology Lookup Service (OLS) is a comprehensive platform developed by EMBL-EBI, designed to serve as a unified repository for biomedical ontologies. It provides users with a single, accessible point to discover and interact with the most current versions of various ontologies. OLS facilitates this through a user-friendly website, a robust REST API for programmatic access, and an MCP server endpoint for machine-readable information. Internally, it leverages specialized database servers like Solr for full-text search and Neo4j for efficient recursive graph queries, enabling powerful exploration and analysis of interconnected knowledge within the biomedical domain.
