HyTime follows a similar model. From the standard:
3.1 anchor: An object (or aggregation of objects) that is linked by a
hyperlink.
NOTE 9 The term "object" is not a formal construct in HyTime; an anchor
could be a document, an element, an arbitrary chunk of data, or any
other thing.
NOTE 10 An object is an anchor if and only if a hyperlink identifies
it as such.
NOTE 11 An object could be identified as an anchor by several link
ends, in the same or different hyperlinks.
3.15 hyperlink: An information structure that represents a relationship
among two or more objects.
NOTE 22 Objects that are related by a hyperlink are called the "anchors"
of the hyperlink. An anchor is identified by a property of the
hyperlink called a "link end".
NOTE 23 Hyperlinks can be assigned link types and names by applications
and architectures that use HyTime.
