Media Attachments
|
||
-----------------
|
||
|
||
Media attachments (images, videos, and other files) may be added to events by including a URL in the event content, along with a matching `imeta` tag.
|
||
|
||
`imeta` ("inline metadata") tags add information about media URLs in the event's content. Each `imeta` tag SHOULD match a URL in the event content. Clients may replace imeta URLs with rich previews.
|
||
|
||
The `imeta` tag is variadic, and each entry is a space-delimited key/value pair.
|
||
Each `imeta` tag MUST have a `url`, and at least one other field. `imeta` may include
|
||
any field specified by [NIP 94](./94.md). There SHOULD be only one `imeta` tag per URL.
|
||
|
||
## Example
|
||
|
||
```json
|
||
{
|
||
"content": "More image metadata tests don’t mind me https://nostr.build/i/my-image.jpg",
|
||
"kind": 1,
|
||
"tags": [
|
||
[
|
||
"imeta",
|
||
"url https://nostr.build/i/my-image.jpg",
|
||
"m image/jpeg",
|
||
"blurhash eVF$^OI:${M{o#*0-nNFxakD-?xVM}WEWB%iNKxvR-oetmo#R-aen$",
|
||
"dim 3024x4032",
|
||
"alt A scenic photo overlooking the coast of Costa Rica",
|
||
"x <sha256 hash as specified in NIP 94>",
|
||
"fallback https://nostrcheck.me/alt1.jpg",
|
||
"fallback https://void.cat/alt1.jpg"
|
||
]
|
||
]
|
||
}
|
||
```
|
||
|
||
## Recommended client behavior
|
||
|
||
When uploading files during a new post, clients MAY include this metadata
|
||
after the file is uploaded and included in the post.
|
||
|
||
When pasting URLs during post composition, the client MAY download the file
|
||
and add this metadata before the post is sent.
|
||
|
||
The client MAY ignore `imeta` tags that do not match the URL in the event content.
