Summary

This document outlines a process for extracting and interpreting data, particularly for handling H-Card structures and authorship information. It describes how to treat various data types – plain strings, img alt structures, and embedded HTML – to identify and utilize properties like name, photo, and URL. Key strategies include:

* Plain Strings: Treating non-URL strings as H-Card names.
* Img Alt Structures: Using alt text as names and photo URLs as fallback URLs.
* Embedded HTML: Utilizing plaintext content and applying previous approaches.
* URL Strings: Fetching URLs and attempting to find a representative H-Card for the author.
* MF Structures: Fetching URLs with MF structures and using the H-entry/page authorship algorithm if a photo is missing.

The document prioritizes using H-Card structures for authorship and suggests defaulting to the URL hostname as a last resort.
