Examples in the wild
Microformats are fully specced with a comprehensive test suite and are licensed as Public Domain allowing you to freely use them however you want.
If you're a developer working on an app or service, you probably need JSON as your input format. Don't worry. There are several Microformats parsers written in multiple programming languages. A parser will take a URL or a glob of HTML, understand it, then convert it to JSON for your use.
You can test your URL here (or HTML snippet on any of the parser sites).
Other parsers are in-development for: Erlang, Elixir, Haskell, Java, and more.
