Four months after it was announced, the Open Semantic Interchange has a specification anyone can read. OSI published v1 on January 27, 2026.

## What was announced

1. **OSI specification v1**, released under Apache 2.0 at github.com/open-semantic-interchange/OSI.
2. **Databricks joined OSI.**
3. **In the same week, Databricks managed MCP servers moved to public preview.**

## Why it matters

A spec on GitHub under an open license is something teams can test and build against today, not a promise. Four months from announcement to v1 is fast for a standard.

Databricks joining matters more than the date. A semantic interchange standard is only as useful as the platforms that read and write it. With Snowflake and Databricks both members, a definition built in one has a path into the other.
