NIP-41
======
Relational Database
-------------------
`draft` `optional`
This NIP offers a plug-and-play method to export/sync information from existing systems using relational databases into Nostr.
Event kind `31200` represents a row in a database. Each value of the row is added as a tag whose name is the column's name.
The `d` tag is used for the row's primary key, the `n` tag places the row into an unbound list to represent the table and the `u` tag references a database name.
Values can be public or encrypted to the user.
```js
{
"kind": 31200,
"tags": [
2024-04-09 17:38:11 -04:00
["d", "<database-name:table-name:row-primary-key>"]
["n", "<table-name>"]
["u", "<database-name>"]
["<column-name>", "<column-row-value>"]
// other public columns
],
"content": nip44Encrypt(JSON.stringify((
[
["<column-name>", "<column-row-value>"]
// other private columns
]
)),
// .. other fields
}
```
Inserts and updates are supported via Nostr's regular signing operations and deletions via [NIP-09](09.md).
The pubkey MAY be own by the system and represent several users from that system.
