NIP-23

Long-form Content

draft optional author:fiatjaf

This NIP defines kind:30023 (a parameterized replaceable event according to NIP-33) for long-form text content, generally referred to as "articles" or "blog posts".

"Social" clients that deal primarily with kind:1 notes should not be expected to implement this NIP.

Format

The .content of these events should be a string text in Markdown syntax, including YAML front-matter for other metadata that may be necessary.

Metadata

This NIP defines only title as the metadata. For the date of publication the event .created_at field should be used, and for "tags"/"hashtags" (i.e. topics about which the event might be of relevance) the "t" event tag should be used, as in NIP-12.

Editability

These articles are meant to be editable, so they should make use of the replaceability feature of NIP-33 and include a "d" tag with an identifier for the article. Clients should take care to only publish and read these events from relays that implement that. If they don't do that they should also take care to hide old versions of the same article they may receive.

Linking

The article may be linked to using the NIP-19 nitem code along with the "i" tag (see NIP-33 and NIP-19).

References

Writing clients should implement support for parsing pasted NIP-19 nitem identifiers and adding them automatically to the list of .tags of the event, replacing the actual content with a string like #[tag_index] in the same way as NIP-08 -- or, if the reference is in the form of a URL (for example, [click here](nitem1...)) then they should be replaced with just the tag number directly as if link with that name existed at the bottom of the Markdown (for example, [click here][0]).

Reader clients should parse the Markdown and replace these references with either internal links so the referenced events can be accessed directly, with NIP-21 nostr:nitem1... links or direct links to web clients that will handle these references.

The idea here is that having these tags is that reader clients can display a list of backreferences at the bottom when one article mentions another.

The same principles can be applied to nevent1..., note1..., nprofile1... or npub1....
