- What standards are there?
- How could it be used?
- How is it actually used?
- Why don’t we use it more?
- Should I use it on my web pages/apps?

- Schema.org – Microdata schema definition site.
- Open Graph – The meta tag side of Open Graph (not the Facebook App side).
- Microformats – An older standard, mostly superceded by Microdata.
- Google’s Microdata Support – Specifically, look at the bottom to see the list of entities they support
- Google drops support for authorship metadata
- Structured Data Testing Tool – Use this to test if you’re correctly adding your semantic metadata.
- Extracted metadata from one of my websites – This is my D&D game on Obsidian Portal. You can see the metadata extracted.
- Extracted metadata from my profile – This is Micah’s profile page on Obsidian Portal. It gives a lot of metadata about Micah.
- OG Linter – Help debug your Open Graph meta tags. (Suggested by Melinda in the comments.)
