This NIP defines kind:25 as a simple plaintext note that is limited to 210 visible characters.
The .content property contains some human-readable text.
Clients MUST force outgoing .content to be less or equal to 210 characters and crop all incoming events to the same amount.
Relays MUST not accept .content with over 210 chars, considering the rules below.
Markup languages such as markdown MUST NOT be used.
Replies to kind:25 MUST use NIP-22 comments while applying the same .content rules as defined here.
Reactions MUST use NIP-25 with a k tag to 25. Clients MUST only download and display reactions that include the k=25 tag for its notifications.
Zap Events MUST also include the k tag of the source event. Clients MUST only render zaps that include the k=25 tag in notifications.
Tiny notes strongly rely on in-event caches to speed up the rendering process and calculate the 210-char limit.
User citations MUST use a variation of NIP-19's nostr:nprofile urls with a 4th TLV type that receives the current display name of the user. The user's display name MUST be used to match the 210 limit. p tags SHOULD only be added if the logged-in user wants to notify the tagged user.
Quoted notes that are kind:25 MUST use NIP-19's nostr:nevent with a 4th TLV type including the quoted text. The quoted text MUST be used to match the 210 limit. The q tag MUST be added to all quoted events.
Quoted notes that are not kind:25 MUST not be previewed or rendered by the client. Instead, the Client must render the quoted text from the TLV with a link. The link should open a separate app that can render those events using NIP-89. The q tag MUST be used.
Links to images MUST include NIP-92 imeta tags with required fields: url, m, blurhash, dim, and x and should be previewed in full-width mode. If the imeta tags are not present, images MUST not be previewed and stay as a link. If the x hash doesn't match the file hash, the image should not be previewed and stay as a link.
Links to websites MUST include PR1674 open graph tags and should be previewed in full-width mode. If the open graph tags are not present, url MUST not be previewed and stay as a link.
