When I joined the IndieWeb community, I discovered the concept of "microformats." Microformats are a way in which you can add structured data in the same HTML tags you use to mark up the structure of a document. This works because microformats only needs you to add certain keywords to your HTML classes to function.
Assumed knowledge: This post assumes technical knowledge with microformats2. This post is most useful for someone debugging authorship relations on their h-feed or for community members who want to discuss documenting this pattern.
