/**
 * JRD (Json [extensible] Resource Descriptor) objects are better known as "Webfinger response objects". They
 * contain meta-information about a host or, in the ActivityPub/Webfinger case, one of the host's users.
 * 
 * <p> RFC 7033 describes the process to obtain this object. RFC 6415 Appendix A describes this object itself.
 * But badly, in relation to the XRD spec.
 * 
 * <p> The query for this object typically looks like "https://example.com/.well-known/webfinger?resource=acct:exampleuser@example.com".
 * Ideally, your headers would include "Accept=application/jrd+json" because that sure as heck is what you're going to get.
