Ataccama Launches Data Products and Joins Open Semantic Interchange

Ataccama announced new data product capabilities in Ataccama ONE and its membership in the Open Semantic Interchange (OSI) consortium, per a GlobeNewswire press release dated June 2, 2026, timed to Snowflake's annual user conference, Snowflake Summit 26. The release states that organizations can define core business concepts, such as Customer, Transaction, Supplier, and Asset, as governed data products, each with a named owner, a verified definition, and an Ataccama Data Trust Index score. Per the release, those trust scores and business context are delivered via Ataccama's MCP Server into Snowflake CoCo, Cortex CoWork, and enterprise AI tools to expose a single, trusted, AI-ready version of business data.

Per the GlobeNewswire release, the Ataccama Data Trust Index is a weighted score from 0 to 100 that continuously measures each data product across data quality, ownership completeness, and business context. The release describes Ataccama ONE organizing data around business meaning and mapping each data product to all datasets that hold that information across systems, applying governance and authoritative-source metadata at the concept level. The MCP Server acts as the runtime conduit so tools such as CoCo can consume Data Trust Index scores and ground AI work in governed, verified data without moving it outside Snowflake. The release adds that Ataccama is joining OSI as a collaborator and acting as a launch partner for Snowflake's Agentic Data Sharing program.

Exposing semantic metadata and evidence-based trust signals alongside data reduces ambiguity for downstream AI processes such as retrieval-augmented generation and agent workflows. As a general pattern, attaching provenance, quality metrics, and ownership metadata to business concepts helps automated systems make more defensible decisions and simplifies policy enforcement when models access enterprise data.

The announcement sits within a broader trend where data-governance vendors and platform providers integrate to supply trust layers for enterprise AI. Snowflake-centric deployment paths, including CoCo and Cortex CoWork, reflect rising demand for runtime access to governed semantics rather than raw tables, and OSI is positioned as a way to move shared semantics across platforms without vendor lock-in.

• •Adoption signals for these data-product APIs within Snowflake-driven stacks, such as connector listings or case studies.
• •Whether third-party tools actually consume the Data Trust Index signals, and how the index maps to enterprise SLAs.
• •OSI specification uptake and practical interoperability between vendors sharing semantic metadata.
