Open standard · Apache 2.0

FLUID.

Federated · Layered · Universal · Instructional · Declarative.
The open standard for enterprise data products in the agentic era.

The six pillars

Five letters. One principle.

Five principles spell FLUID — and the sixth pillar, data treated as a product, is the one that underwrites them all.

F

Federated Ownership

Domain experts own their data. Accountability lives where the knowledge lives.

L

Labeled & Discoverable

Rich metadata. Agents find it, understand it, trust it.

U

Unifying Standards

Common protocols across domains, without constraining what each domain builds.

I

Instructional & Self-Service

Every product is self-documenting. No one needs to ask what it is.

D

Declarative

Declare the outcome. The compiler does the rest.

Data as Product

Defined owner, contract, version, SLO, support. Treated like a product.

Three tiers · Data-Mesh-aligned

SDP → ADP → CDP.

Source-aligned → Aggregate → Consumer-aligned. Bound to the FLUID contract.

Raw with context

SDP

Source-aligned

Ingested directly from a source system. Lineage and metadata attached at entry.

Composable

ADP

Aggregate

Domain-cleaned, entity-resolved, contract-bound. The building blocks.

Purpose-built

CDP

Consumer-aligned

Designed for a specific business outcome. Agent-ready by default.

iAPIs

Agents can read this.

Intelligent Agentic Protocol Interfaces. Not a conventional API — a semantic interface agents understand by intent, not just by name. Discover, evaluate, act — no human in the loop.

discoverable contract-bound policy-aware low-latency

Open source

The standard belongs
to everyone.

forge-cli and the FLUID standard are Apache-2.0 licensed — free to use, fork, audit and ship, forever. We build it in the open because a protocol the whole industry can trust is worth far more than one any single company owns.

forge-cli · the FLUID standard

Apache 2.0 — no asterisks

Permissive and irrevocable. Use it in anything, commercial or not — no permission, no royalties, no rug-pull.

No lock-in, ever

Stop trusting us tomorrow? Fork it. The contract format and the compiler are yours to keep and run.

Built with the community

Issues, PRs and proposals welcome. The roadmap is public — the conversation happens in the open.

Build on the standard.

FLUID is open, versioned, and Apache 2.0. Read the spec and write your first contract.
