This NIP defines `kind:30818` (an _addressable event_) for descriptions (or encyclopedia entries) of particular subjects, and it's expected that multiple people will write articles about the exact same subjects, with either small variations or completely independent content.
Unlike normal Asciidoc links `http://example.com[]` that link to external webpages, wikilinks `[[]]` link to other articles in the wiki. In this case, the wiki is the entirety of Nostr. Clicking on a wikilink should cause the client to ask relays for events with `d` tags equal to the target of that wikilink.
1.`[[Target Page]]` -- in this case it will link to the page `target-page` (according to `d` tag normalization rules above) and be displayed as `Target Page`;
2.`[[target page|see this]]` -- in this case it will link to the page `target-page`, but will be displayed as `see this`.
`nostr:...` links, as per [NIP-21](21.md), should link to profiles or arbitrary Nostr events. Although it is not recommended to link to specific versions of articles -- instead the _wikilink_ syntax should be preferred, since it should be left to the reader and their client to decide what version of any given article they want to read.
### Optional extra tags
-`title`: for when the display title should be different from the `d` tag.
-`summary`: for display in lists.
-`a` and `e`: for referencing the original event a wiki article was forked from.
Event `kind:818` represents a request to merge from a forked article into the source. It is directed to a pubkey and references the original article and the modified event.

### Redirects
Event `kind:30819` is also defined to stand for "wiki redirects", i.e. if one thinks `Shell structure` should redirect to `Thin-shell structure` they can issue one of these events instead of replicating the content. These events can be used for automatically redirecting between articles on a client, but also for generating crowdsourced "disambiguation" pages ([common in Wikipedia](https://en.wikipedia.org/wiki/Help:Disambiguation)).

How to decide what article to display
-------------------------------------
As there could be many articles for each given name, some kind of prioritization must be done by clients. Criteria for this should vary between users and clients, but some means that can be used are described below:
### Reactions
[NIP-25](25.md) reactions are very simple and can be used to create a simple web-of-trust between wiki article writers and their content. While just counting a raw number of "likes" is unproductive, reacting to any wiki article event with a `+` can be interpreted as a recommendation for that article specifically and a partial recommendation of the author of that article. When 2 or 3-level deep recommendations are followed, suddenly a big part of all the articles may have some form of tagging.
### Relays
[NIP-51](51.md) lists of relays can be created with the kind 10102 and then used by wiki clients in order to determine where to query articles first and to rank these differently in relation to other events fetched from other relays.
### Contact lists
[NIP-02](02.md) contact lists can form the basis of a recommendation system that is then expanded with relay lists and reaction lists through nested queries. These lists form a good starting point only because they are so widespread.
### Wiki-related contact lists
[NIP-51](51.md) lists can also be used to create a list of users that are trusted only in the context of wiki authorship or wiki curationship.
Forks
---------
Wiki-events can tag other wiki-events with a `fork` marker to specify that this event came from a different version. Both `a` and `e` tags SHOULD be used and have the `fork` marker applied, to identify the exact version it was forked from.
Deference
---------
Wiki-events can tag other wiki-events with a `defer` marker to indicate that it considers someone else's entry as a "better" version of itself. If using a `defer` marker both `a` and `e` tags SHOULD be used.
This is a stronger signal of trust than a `+` reaction.
This marker is useful when a user edits someone else's entry; if the original author includes the editor's changes and the editor doesn't want to keep/maintain an independent version, the `link` tag could effectively be a considered a "deletion" of the editor's version and putting that pubkey's WoT weight behind the original author's version.
Wikitext is [garbage](nostr:nevent1qqsqt0gcggry60n72uglhuhypdlmr2dm6swjj69jex5v530gcpazlzsprpmhxue69uhhyetvv9ujumn0wdmksetjv5hxxmmdqy28wumn8ghj7un9d3shjtnyv9kh2uewd9hsygpm7rrrljungc6q0tuh5hj7ue863q73qlheu4vywtzwhx42a7j9n5ueneex) and Markdown is not powerful enough (besides being too freeform and unspecified and prone to generate incompatibilities in the future).
Asciidoc has a strict spec, multiple implementations in many languages, and support for features that are very much necessary in a wiki article, like _sidebars_, _tables_ (with rich markup inside cells), many levels of _headings_, _footnotes_, _superscript_ and _subscript_ markup and _description lists_. It is also arguably easier to read in its plaintext format than Markdown (and certainly much better than Wikitext).
The destination-pubkey is the pubkey being requested to merge something into their article can create [[NIP-25]] reactions that tag the `kind:818` event with `+` or `-`
