Inline Resource Metadata
------------------------
`draft` `optional` `author:arthurfranca` `author:Giszmo` `author:jb55` `author:vitorpamplona`
Inline resource metadata is additional information associated with urls in notes that clients can optionally use to enhance resource loading.
It uses [URI Fragment](https://en.wikipedia.org/wiki/URI_fragment) that agents (such as web browsers) never send to the server. Because of this, the url is fetched **without** the fragment parameters, unlike using query parameters.

Multiple array values use repeated names and are positioned in the same order of ocurrence in the tag array. For instance, `["aes-256-gcm", 'i-am-a-key', 'i-am-an-iv']` becomes `aes-256-gcm=i-am-a-key&aes-256-gcm=i-am-an-iv`.
### Event Example:
## Usage
An url with added metadata can be used anywhere a normal url can, whether embedded in an event's `.content` field or as an event tag value.
### Example:
```js
{
"kind": 1,
"content": "What a great place! https://xyz.com/example.jpg#m=image%2Fjpeg&dim=3024x4032&alt=A%20scenic%20photo%20overlooking%20the%20coast%20of%20Costa%20Rica&blurhash=eVF%24%5EOI%3A%24%7BM%7Bo%23*0-nNFxakD-%3FxVM%7DWEWB%25iNKxvR-oetmo%23R-aen%24`",
"content": "What a great place! https://xyz.com/filename#m=image%2Fjpeg&dim=1920x1080`",
// ... other event fields
}
```
## Tag Usage
When publishing events of kinds designed with urls inside tags instead of in `.content`, use `media` tags specifically for image, audio and video
or else pick another tag such as `r`. One may also add `media` tags to events to aid in loading media placeholders on clients that postpone or don't do event `.content` parsing.
### Tag Examples:
An image with MIME type, dimensions and blurhash:
`["media", "https://xyz.com/image001.png#m=image%2Fpng&dim=1342x704&blurhash=MnR3f%2C%25M%252%25MjZ~Wj%40j%5Bt7Rjs%3Aayfkj%5BWB%5C"]`
A kind 30023 event JSON file (with `nostr/30023` MIME type):
`["r", "https://xyz.com/example.json#m=nostr%2F30023"]`
## Recommended client behavior
When uploading images during a new post, clients can collect metadata
