# Multi-tenant norms

> Why norms are scoped to your organization rather than a shared public corpus — and what that means for licensing and privacy.

Stratta does **not** host a shared, central library of norms. Each organization brings and stores
its own. This page explains why, and what it means for you.

## The model

Every norm belongs to exactly one **organization** (your workspace). When you ingest a norm, it's
written with your organization's id and is visible only to members of that organization, through
their own Claude. There is no global corpus that everyone queries.

## Why it's built this way

  <Card title="Copyright compliance" icon="scale-balanced">
    SIA standards and Eurocodes are licensed, copyrighted documents. Scoping norms per
    organization means each company supplies the norms it is licensed for — Stratta never
    redistributes them.
  </Card>

  <Card title="Confidentiality" icon="eye-slash">
    Your ingested norms — and any annotations in them — stay within your workspace. Other
    organizations can't see them.
  </Card>

## How isolation is enforced

Isolation is enforced **on the server**, not by the client:

* Every MCP request is authenticated by your API key.
* The server resolves your key to an organization and filters every query and write by that
  organization.
* The organization id is **never** a parameter the client can set — it's derived from your key.

So even though many organizations share the same backend, one organization can never read or
write another's norms. See [Security](/en/concepts/security) for the full model.

## What this means in practice

* **You ingest the norms you need.** See [Ingest a norm](/en/guides/ingest-a-norm).
* **Your team shares them.** Everyone in your organization can query the norms you've ingested.
  See [Manage your organization](/en/guides/manage-organization).
* **You're responsible for licensing.** Only ingest norms your organization is licensed for.

<Note>
  The Stratta demo workspace ships with SIA 260 and SIA 261-1 ingested as examples. Your own
  workspace starts empty — you choose what to add. See [Supported norms](/en/resources/supported-norms).
