What exactly are Link Relation Values?
- by bckpwrld
From REST in Practice: Hypermedia and Systems Architecture:
For computer-to-computer interactions, we advertise protocol
information by embedding links in representations, much as we do with
the human Web. To describe a link's purpose, we annotate it.
Annotations indicate what the linked resource means to the current
resource: “status of your coffee order” “payment” and so on. We call
such annotated links hypermedia controls, reflecting their enhanced
capabilities over raw URIs.
... link relation values, which describe the roles of linked resources ...
Link relation values help consumers understand why they might want to
activate a hypermedia control. They do so by indicating the role of
the linked resource in the context of the current representation.
I interpret the above quotes as saying that Hypermedia control contains both a link to a resource and an annotation describing the role of linked resource in the context of the current representation. And we call this annotation ( which describes the role of linked resource ) a link relation value.
Is my assumption correct or does the term link relation value actually describe something different?
Thank you
