Open Semantic Interchange Is Now Apache Ossie (Incubating) — a JSON/YAML Spec So AI Agents Stop Computing the Same KPI Three Different Ways

GitHub·medium signal

apache/ossie (1,642 stars, +423 this week) entered Apache incubation under a new name, formerly Open Semantic Interchange. It standardizes semantic model exchange across data analytics, AI, and BI tooling, targeting the failure mode where identical KPIs are defined differently per tool and AI systems then produce unreliable output from inconsistent business logic. The repo ships a JSON/YAML specification, reference converters for dbt, GoodData, Polaris, and Salesforce, validation tooling, and example models including a complete TPC-DS dataset. For anyone pointing agents at a warehouse, this is the missing contract layer — though incubating status and 1.6K stars mean adoption is early.
