Building on the original Delta Sharing protocol, OpenSharing defines a cross-platform, vendor-neutral protocol for secure zero-copy sharing of Data and AI assets. Customers can use a consistent set of discovery API, credential vending model, and access controls across tables, volumes, ML models, and agent skills. Any compliant client on any platform can consume any asset type without format-specific or platform-specific code – breaking down silos and enabling open collaboration.

OpenSharing was donated to LF AI & Data Foundation by Databricks as a Sandbox-tier project and approved by the LF AI & Data TAC for onboarding in August 2026.
