I see you’ve shared the full HTML of the Open Graph Protocol (ogp.me) specification page.

Here’s a structured breakdown of what this document is showing:

Overview

The Open Graph Protocol (OGP) allows any webpage to become a “rich object” within a social graph (such as Facebook, LinkedIn, or other platforms). By adding <meta> tags inside the <head> of an HTML page, developers can specify how the page should appear when shared.

Required Metadata

Every page needs four core properties:

  1. og:title – Title of the object (e.g., “The Rock”).
  2. og:type – The object’s type (e.g., website, video.movie, etc.).
  3. og:image – A representative image (URL).
  4. og:url – The canonical URL (permanent ID in the graph).

Optional Metadata

Additional recommended properties include:

  • og:audio– An audio file.
  • og:description– A short description.
  • og:determiner– Word before title (e.g., “the”).
  • og:locale/ og:locale:alternate – Page locale(s).
  • og:site_name– Parent site name.
  • og:video– A related video.

Structured Properties

Some objects (image, video, audio) allow extended metadata:

  • For images:
    • og:image:url, og:image:secure_url, og:image:type, og:image:width, og:image:height, og:image:alt.
  • For videos:
    • Same properties as image.
  • For audio:
    • og:audio, og:audio:secure_url, og:audio:type.

Arrays

Multiple <meta> tags can be used if a property has several values (e.g., multiple og:image entries).

Object Types

  • Musicmusic.song, music.album, music.playlist, music.radio_station.
  • Videovideo.movie, video.episode, video.tv_show, video.other.
  • Articles/Books/Profiles/Payments/Websitesarticle, book, payment.link, profile, website.

Each has its own additional metadata (e.g., book:isbn, article:author, video:actor).

Supported Data Types

The spec defines valid types for properties:

  • Boolean
  • DateTime (ISO 8601)
  • Enum
  • Float
  • Integer
  • String
  • URL

Developer Tools

  • Facebook Debugger
  • Google Rich Snippets Testing Tool
  • Librariesin PHP, Python, Ruby, Java, Perl, etc.

✅ In short: This HTML is the official Open Graph Protocol documentation, which explains how to add OGP <meta> tags in a webpage’s <head> section so platforms like Facebook, LinkedIn, or Twitter can generate rich previews.

Would you like me to summarize this into a practical implementation guide (with a modern example for SEO + social sharing), or do you prefer a line-by-line explanation of the HTML you pasted?
