OpenSharing Launches on Linux Foundation: Zero-Copy Protocol Replaces AI Asset Integrations

The Linux Foundation launched the OpenSharing Project on June 10, 2026, giving enterprises building agentic AI a single open protocol to share AI models, agent skills, and unstructured data across any platform — without copying files, writing custom integrations, or staying locked inside a single vendor’s marketplace. For any organization running agentic AI workflows that span multiple clouds, tools, or business partners, the arrival of an openly governed standard means the cost and friction of cross-organizational AI collaboration just dropped significantly.

OpenSharing is the evolution of Delta Sharing, the open data-sharing protocol Databricks launched in 2021. Where Delta Sharing focused on structured tabular data, OpenSharing extends the same REST-based, zero-copy architecture to the full range of assets organizations are now trading in the agentic era: agent skills, machine learning models, and unstructured data volumes, alongside the structured tables Delta Sharing already handled. Databricks donated the protocol to the Linux Foundation, making it community-governed under an Apache 2.0 license — the same structural move that turned Delta Sharing from a Databricks tool into a cross-industry standard adopted by thousands of enterprises and used in tools including Apache Spark, Oracle, Power BI, Tableau, and Snowflake.

Zero-Copy REST Architecture Keeps Data Where It Lives

The technical mechanism at the heart of both Delta Sharing and OpenSharing is a design choice with direct implications for security and compliance: data never moves through a broker or a central server. The OpenSharing protocol specification defines a REST API in which what a recipient receives is not the data itself but a short-lived, signed access credential.

When a provider shares an asset, that credential — a bearer token or an OpenID Connect (OIDC) federation token — grants time-limited, read-only access directly to the provider’s cloud object storage. The recipient’s tool (Apache…
