This post discusses the Open Graph protocol, a way to display and share information about web resources on the internet, particularly when sharing websites and URLs on social media platforms like Twitter and Facebook. It explains how to create an app using Contentful's App Framework that can handle complexity and pass data between different app locations, making it useful for creating cohesive experiences for editors as they work on content that is meant to be visualized in different ways. The post guides through the process of creating a new content type called "Open Graph" with fields such as title, content, image, and URL, and then building an app using React that can automatically generate titles based on referenced blog posts and display previews of the Open Graph data.
