FLUID
One declarative contract for trustworthy, governable, agent-ready data products.
Contract-First
One .fluid.yml is the source of truth — schema, quality, build, lineage, governance. Version-controlled and schema-validated.
Agentic-Native
agentPolicy, sovereignty, and semantics give LLM agents machine-readable answers to PII, allowed-use, metric, and residency questions — and an MCP gateway can enforce them on every read.
Operational Superset
Covers build, orchestration and source-aligned acquisition alongside the data contract and its governance.
Interoperable
Compiles to Bitol ODPS + ODCS via the forge-cli reference implementation for DataHub / OpenMetadata / Datamesh Manager catalog interop.
Federated by Design
Built for Data Mesh — decentralized ownership, globally unique product ids, one unified fabric.
Open & Apache 2.0-Licensed
An open specification under the Apache License 2.0, with a public conformance corpus and no CLA.
Your agents are only as trustworthy as the data products they consume.
FLUID is one YAML file that describes a data product end to end — schema, build, orchestration, agentic governance, sovereignty, and semantics. Write it once; validate it, compile it, and deploy it anywhere.
