The BEL Language

The Biological Expression Language (BEL) is a language for representing scientific findings in the life sciences in a computable form. BEL is designed to represent scientific findings by capturing causal and correlative relationships in context, where context can include information about the biological and experimental system in which the relationships were observed, the supporting publications cited and the curation process used.

The BEL Framework

The BEL Framework is an emerging open-platform technology specifically designed to overcome many of the challenges associated with capturing, integrating, and storing knowledge within an organization, and sharing the knowledge across the organization and between business partners.

Bringing knowledge to life!

Welcome to the OpenBEL Portal! 

This site is designed as an online resource for BEL, the BEL Framework, and associated technologies, tools, and content. The BEL Framework is a unique new technology platform for managing, publishing, and using structured life-science knowledge. What makes it unique? For starters, it’s an open technology, which means that you or your organization can start using it immediately.  We are also making some BEL content available to get you started.

What is the BEL Framework? 

Put simply, it's a collection of software components and specifications that work together to provide a suite of tools for capturing scientific facts in a use-neutral form and making those facts available to applications in a well-documented and easy-to-use interface. Central to the BEL Framework is BEL, the Biological Expression Language, a technology developed and used by Selventa for almost a decade.  BEL has evolved into a pragmatic, easy-to-understand language designed to unambiguously capture scientific facts and what is known about how those facts were discovered.
