Open Semantic Interchange

open-semantic-interchange.org

The Open Semantic Interchange (OSI) is an open-source, vendor-neutral specification designed to standardize the exchange of semantic metadata across analytics, AI, and BI platforms. It utilizes a declarative YAML configuration to define metrics, dimensions, and joins, creating a single source of truth that ensures consistent data definitions. This standard enables seamless interoperability between disparate tools, reduces metric drift, and provides reliable semantic context for AI agents.
