A `REQ` message may contain multiple filters. In this case, events that match any of the filters are to be returned, i.e., multiple filters are to be interpreted as `||` conditions.
The `limit` property of a filter is only valid for the initial query and MUST be ignored afterwards. When `limit: n` is present it is assumed that the events returned in the initial query will be the last `n` events ordered by the `created_at`. It is safe to return less events than `limit` specifies, but it is expected that relays do not return (much) more events than requested so clients don't get unnecessarily overwhelmed by data.

When `limit: n` is present it is assumed that the events returned in the initial query will be the last `n` events ordered by the `created_at`.

### Recommendation to Extension Authors
To make sure that the `window.nostr` is available to nostr clients on page load, the authors who create Chromium and Firefox extensions should load their scripts by specifying `"run_at": "document_end"` in the extension's manifest.

Community management clients MAY filter all mentions to a given `kind:34550` event and request moderators to approve each submission. Moderators MAY delete his/her approval of a post at any time using event deletions (See [NIP-09](09.md)). # Moderation
# Post Approval by moderators Anyone may issue an approval event to express their opinion that a post is appropriate for a community. Clients MAY choose which approval events to honor, but SHOULD at least use ones published by the group's defined moderators.
The post-approval event MUST include `a` tags of the communities the moderator is posting into (one or more), the `e` tag of the post and `p` tag of the author of the post (for approval notifications). The event SHOULD also include the stringified `post request` event inside the `.content` ([NIP-18-style](18.md)) and a `k` tag with the original post's event kind to allow filtering of approved posts by kind. An approval event MUST include one or more community `a` tags, an `e` or `a` tag pointing to the post, and the `p` tag of the author of the post (for approval notifications). `a` tag prefixes can be used to disambiguate between community and replaceable event pointers (community `a` tags always begin with `34550`).

It's recommended that multiple moderators approve posts to avoid deleting them from the community when a moderator is removed from the owner's list. In case the full list of moderators must be rotated, the new moderator set must sign new approvals for posts in the past or the community will restart.

The owner can also periodically copy and re-sign of each moderator's approval events to make sure posts don't disappear with moderators.
Post Approvals of replaceable events can be created in three ways: (i) by tagging the replaceable event as an `e` tag if moderators want to approve each individual change to the replaceable event; (ii) by tagging the replaceable event as an `a` tag if the moderator authorizes the replaceable event author to make changes without additional approvals and (iii) by tagging the replaceable event with both its `e` and `a` tag which empowers clients to display the original and updated versions of the event, with appropriate remarks in the UI. Since relays are instructed to delete old versions of a replaceable event, the `.content` of an `e`-approval MUST have the specific version of the event or Clients might not be able to find that version of the content anywhere. Approvals of replaceable events can be created in three ways:
Clients SHOULD evaluate any non-`34550:*` `a` tag as posts to be included in all `34550:*` `a` tags. 1. By tagging the replaceable event as an `e` tag if moderators want to approve each individual change to the replaceable event
2. By tagging the replaceable event as an `a` tag if the moderator authorizes the replaceable event author to make changes without additional approvals and
3. By tagging the replaceable event with both its `e` and `a` tag which empowers clients to display the original and updated versions of the event, with appropriate remarks in the UI.
# Displaying Since relays are instructed to delete old versions of a replaceable event, the `content` of an approval using an `e` tag MUST have the specific version of the event or clients might not be able to find that version of the content anywhere.
Community clients SHOULD display posts that have been approved by at least 1 moderator or by the community owner. Clients SHOULD evaluate any non-`34550:*` `a` tag as posts to be approved for all `34550:*` `a` tags.
The following filter displays the approved posts. # Cross-posting
```json Clients MAY support cross-posting between communities by posting a NIP 18 `kind 6` or `kind 16` repost to one or more communities using `a` tags as described above. The `content` of the repost MUST be the original event, not the approval event.

======
External Content IDs
-------------------------
`draft` `optional`
There are certain established global content identifiers that would be useful to reference in nostr events so that clients can query all events assosiated with these ids.
- Book [ISBNs](https://en.wikipedia.org/wiki/ISBN)
- Podcast [GUIDs](https://podcastnamespace.org/tag/guid)
- Movie [ISANs](https://en.wikipedia.org/wiki/International_Standard_Audiovisual_Number)
Since the `i` tag is already used for similar references in kind-0 metadata events it makes sense to use it for these content ids as well.
## Supported IDs
### Books:
- Book ISBN: `["i", "isbn:9780765382030"]` - https://isbnsearch.org/isbn/9780765382030
Book ISBNs MUST be referenced _**without hyphens**_ as many book search APIs return the ISBNs without hyphens. Removing hypens from ISBNs is trivial, whereas adding the hyphens back in is non-trivial requiring a library.
### Podcasts:
- Podcast RSS Feed GUID: `["i", "podcast:guid:c90e609a-df1e-596a-bd5e-57bcc8aad6cc"]` - https://podcastindex.org/podcast/c90e609a-df1e-596a-bd5e-57bcc8aad6cc
- Podcast RSS Item GUID: `["i", "podcast:item:guid:d98d189b-dc7b-45b1-8720-d4b98690f31f"]`
- Podcast RSS Publisher GUID: `["i", "podcast:publisher:guid:18bcbf10-6701-4ffb-b255-bc057390d738"]`
### Movies:
- Movie ISAN: `["i", "isan:0000-0000-401A-0000-7"]` - https://web.isan.org/public/en/isan/0000-0000-401A-0000-7
Movie ISANs SHOULD be referenced _**without the version part**_ as the versions / edits of movies are not relevant. More info on ISAN parts here - https://support.isan.org/hc/en-us/articles/360002783131-Records-relations-and-hierarchies-in-the-ISAN-Registry
---
### Optional URL Hints
Each `i` tag MAY have a url hint as the second argument to redirect people to a website if the client isn't opinionated about how to interpret the id:
`["i", "podcast:item:guid:d98d189b-dc7b-45b1-8720-d4b98690f31f", https://fountain.fm/episode/z1y9TMQRuqXl2awyrQxg]`
