One source of truth. Every AI starts from it.
SchemaFirst.org is a community for universal, openly governed standards so your organization publishes its authoritative brand, data, and operational context in the format Agents know and expect—so every system begins from the same definitive source instead of rebuilding or hallucinating it.
GTM Data Schema
Canonical objects and vocabularies
Shared data objects and definitions so AI tools and systems interpret the same facts the same way.
Brand Schema
A published Brand Card any compatible AI can discover and retrieve.
Standards Index
Browse every current standard and how they relate to one another.
The problem
Separate prompts create separate versions of your organization.
When every team, contractor, and vendor recreates your brand rules, data definitions, and company context for a different AI tool, definitions conflict, brand drifts, and models infer meaning you never approved. SchemaFirst separates your organizational truth from the tool that happens to consume it.
How it works
Define once. Publish once. Every compatible system starts from the same source.
- 01
Define
Decide what organizational information is authoritative.
- 02
Structure
Express it using the applicable SchemaFirst schema.
- 03
Publish
Post it at a stable, canonical location you own.
- 04
Discover
Systems find the standards you have published.
- 05
Retrieve
Each consumer pulls only the fields relevant to its task.
- 06
Apply
The tool uses that context in its workflow.
- 07
Validate
Outputs are checked against the source and version.
- 08
Update
You change the canonical source; consumers follow.
Not every consumer receives every standard. A design tool may retrieve visual identity fields while a sales agent retrieves product terminology and approved claims—each from the same authoritative source.
Start from the problem you have.
Each page answers one complete operational question and links to the exact standards that apply.
Why SchemaFirst
Why constantly changing AI systems require universal organizational standards in the first place.
Universal Source of Truth
Maintain one definitive source of brand, data, and operational truth without forcing every tool onto one platform.
Reduce Hallucination & Drift
Give AI explicit fields, definitions, and authoritative values instead of leaving it to infer your organization.
Portable AI Context
Change models, tools, or vendors without rebuilding your organization's context from scratch.
Publish your first authoritative source.
Brand Schema is the most direct place to begin. Publish a Brand Card and let compatible tools retrieve it.
