# G01 Personal identity and profile graph

## Question

Which person is this, and which records identify that same person?

## Nodes

Person; ProfilePage; Verified profile; Creative work

## Relationship sketch

* profile.mainEntity → person
* work.author → person
* person.sameAs → exact identity reference

## Evidence inputs

Owner approved public name, actual profile records, bylines, and relationship evidence.

## Implementation

Allocate one stable person identifier. Keep the person separate from biography documents, user accounts, businesses, and people with similar names. Leave unknown properties unset.

## Acceptance checks

* Person and biography page have different identifiers
* Identity links are reviewed for an exact match
* No unverified credential is published

## Do not infer

A descriptive biography, account handle, or confident name match does not prove identity.

## Publication boundary

Approved identity facts may be public; supporting sensitive records stay private.
