Delta Sharing becomes OpenSharing: the open protocol now carries agent skills, AI models and unstructured data without copying
In June 2026 Databricks and the Linux Foundation announced that Delta Sharing has evolved into OpenSharing, extending the open sharing protocol from tables to agent skills, AI models and unstructured data. Previously the open protocol stayed table-centric, so these newer assets remained inside Databricks-to-Databricks sharing. OpenSharing adds a Share-to-Schema-to-Asset hierarchy to the specification, along with Iceberg REST Catalog client support and on-premises or private-cloud storage reach, while existing Delta Sharing clients remain compatible.
