# ShareMember `share.member@1`

Generated at 2026-11-13 06:25:48 UTC from [`openvibe-contracts v0.419.0`](https://github.com/OpenVibers/OpenVibe.Contracts/tree/v0.419.0) and [`openvibe-sdk v0.161.0`](https://github.com/OpenVibers/OpenVibe.SDK/tree/v0.161.0).

- Version: 1.1.0
- Owner: network
- Visibility: public
- Status: active
- Compatibility: backward
- Schema: [`https://openvibe.network/contracts/share/member.v1.json`](/docs/contracts/share.member.json)

share.member@1: a member with their Network identity fields. username, display\_name and avatar\_url are null when Network does not know the subject (or reports it banned or deleted).

## Fields

| Field | Type | Required | Description | Constraints |
| --- | --- | --- | --- | --- |
| `subject` | [identity.subject-ref](/docs/contracts/identity.subject-ref) | yes |  |  |
| `username` | string \| null | yes |  |  |
| `display_name` | string \| null | yes |  |  |
| `avatar_url` | string \| null | yes |  |  |
| `role` | enum | yes |  | - `one of "viewer", "editor"` |
| `expires_at` | string |  |  | - `format date-time` |
| `added_by` | [identity.subject-ref](/docs/contracts/identity.subject-ref) | yes |  |  |
| `added_at` | string | yes |  | - `format date-time` |
| `key_slot` | [locker.people-slot](/docs/contracts/locker.people-slot) |  |  |  |
| `key_fingerprint` | string \| null |  | The member's current key fingerprint from Network's key directory (locker.public-keys@1), shown to the owner of a people-locked item; null when the person has no locker key (or Network did not answer). | - `pattern ^[a-z]+ [a-z]+ [a-z]+ [a-z]+ · [a-z]+ [a-z]+ [a-z]+ [a-z]+$` |
| `fingerprint_changed` | boolean |  | Owner-only, for a people-locked item: true when the member's current key is not the one their key\_slot was made for, so the sheet warns and re-wraps. |  |
