"In this specification, a link is a typed connection between two
resources and is comprised of:
o a link context,
o a link relation type (Section 2.1),
o a link target, and
o optionally, target attributes (Section 2.2).
A link can be viewed as a statement of the form "link context has a
link relation type resource at link target, which has target
For example, "https://www.example.com/" has a "canonical" resource at
"https://example.com", which has a "type" of "text/html".
That's why you need a standardized link component that is globally accepted/understood that takes into account all parts of the linking, instead of having various ways depending on the API/JSON-based Media Type to communicate that something is a link.
