Open Graph is a protocol which enables rich previews on social media. It is heavily used on the web and different messenger apps. See https://ogp.me

Mycorrhiza Wiki supports it and outputs the needed meta tags to enable previews.

  • The name is hypha's name.

  • The image is the first image hypha embeds. If the hypha is an image, that image is shown. If there is no image, favicon is shown instead.

  • The description is hypha's first paragraph.

The author suspects the protocol is not being developed anymore. We're fine with that.
