Adding human.json to WordPress

human.json is a lightweight protocol for asserting authorship and vouching for other humans on the web, similar in spirit to FOAF but using simple JSON. A step-by-step guide shows how to implement it in WordPress by adding a custom rewrite rule and template redirect in PHP, serving the human.json file dynamically with proper CORS headers. An extended version deduplicates and sorts the vouch list, and uses the file modification date as the vouch timestamp.
