short note

PROFILE

The NIP nip10 defines kind:1 as a simple plaintext note.
Markup languages such as markdown and HTML SHOULD NOT be used.

The .content property contains some human-readable text.

Tags: 't' "tags"

example:

{
"content": "This note could be pinned.",
"created_at": 1759402704,
"id": "bcc67ea80da4be50a8ff581bd87910e8c5212fa5b8a240be1fa2263998352237",

LongFormContent

PROFILE

This NIP defines kind:30023 (an addressable event) for long-form text content, generally referred to as "articles" or "blog posts". kind:30024 has the same structure as kind:30023 and is used to save long form drafts.

For the date of the last update the .created_at field should be used, for "tags"/"hashtags" (i.e. topics about which the event might be of relevance) the t tag should be used.

Other metadata fields can be added as tags to the event as necessary. Here we standardize 4 that may be useful, although they remain strictly optional:

• "title", for the article title
• "image", for a URL pointing to an image to be shown along with the title
• "summary", for the article summary
• "published_at", for the timestamp in unix seconds (stringified) of the first time the article was published

The .content of these events should be a string text in Markdown syntax. To maximize compatibility and readability between different clients and devices, any client that is creating long form notes:

• MUST NOT hard line-break paragraphs of text, such as arbitrary line breaks at 80 column boundaries.
• MUST NOT support adding HTML to Markdown.

example:
