## Tag Usage
Metadata fragments are great for sharing urls with extra embedded metadata. They are also good for copying and pasting a resource's url from one note to a new one without losing its metadata.
But some clients can prepare image and video placeholders faster if specific fields are present outside of `.content`.
For these resources, it is suggested to also add `dim`, `alt` and `blurhash`, if available, to media urls inside `resource` tags.
### Event Example: ### Event Example:
```js ```js
{ {
"kind": 1, "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/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`",

]
]
// ... other event fields // ... other event fields
} }
``` ```
Also, some event kinds other than kind 1 and kind 30023 may have been designed with urls inside tags instead of in `.content`. For these cases, use `resource` tags (or `r` tags if it needs to be indexed by relays – in this case, metadata fragment keys and query parameter keys SHOULD be arranged in ascending order). ## Tag Usage
