I’m working on creating a list of metadata formats that a web publisher absolutely must support. These are formats that provide structured information in order to help with one of the following use cases:

- Help platforms to display rich previews when a link from the publisher is shared
- Help search engines to figure out what to display in results, and which information is helpful
- Help third-party clients to interact with web page data in some way (for example to extract information about an event that might be hosted on the publisher’s site)

These might include:

- [Microformats 2](https://microformats.org/wiki/microformats2)
- [Schema.org](https://schema.org/) using [embedded JSON+LD](https://json-ld.org/)
- [Open Graph protocol](https://ogp.me/)
- [Twitter cards](https://developer.twitter.com/en/docs/twitter-for-websites/cards/overview/abouts-cards) (although they’re becoming less relevant these days for obvious reasons)

Additionally, I’ve been thinking about subscription feed formats and standards that a publisher needs to support in order to help users and third-party software platforms to learn about new content.

These might include:

- [RSS](https://en.wikipedia.org/wiki/RSS) with [WebSub](https://www.w3.org/TR/websub/)
- [MRSS](https://en.wikipedia.org/wiki/Media%5FRSS) for syndication to other media properties (like Yahoo News)
- [h-feed](https://microformats.org/wiki/h-feed)
- [ActivityStreams](https://activitystrea.ms/) / [ActivityPub](https://www.w3.org/TR/activitypub/)

What am I missing?

And more importantly, how can we streamline?
