Flycat is a platform that allows users to create and share content in various formats. One of the formats supported on this platform is long-form content, which includes articles and blog posts. To support this type of content, Flycat has implemented NIP-23, which defines a parameterized replaceable event for long-form text content.
In simple terms, NIP-23 is a set of guidelines that allow users to create and share articles on Flycat. These articles are written in Markdown syntax, which is a lightweight markup language that enables users to format text without using complicated HTML tags.
To identify these articles, Flycat uses a specific type of event called "kind:30023". Only clients that deal primarily with long-form content should implement this NIP-23.
When creating an article on Flycat, users can add metadata to provide additional information about the article. For example, they can add tags or hashtags that describe the topics covered in the article. Flycat uses the "t" event tag to identify these tags, as defined in NIP-12.
Users can also add other metadata fields, such as the article title, an image to be shown along with the title, a summary of the article, and the timestamp of the first time the article was published. These fields are optional but can be useful to provide more information about the article.
One of the key features of NIP-23 is that it allows articles to be edited and updated over time. To support this, Flycat uses the replaceability feature defined in NIP-33. Each article has a unique identifier, which is included in a "d" tag. Clients should only publish and read articles from relays that implement replaceability to ensure that the most up-to-date version of the article is being displayed.
Finally, articles can be linked to using the NIP-19 naddr code and an "a" tag. This allows users to easily share their articles and for others to discover related content.
In summary, NIP-23 is a set of guidelines that allows users to create and share long-form content, such as articles and blog posts, on Flycat. By using Markdown syntax and metadata tags, users can provide additional information about their articles, and the replaceability feature ensures that articles can be edited and updated over time.
