As far as I can tell, oa:equivalent is not modeled in
http://www.openannotation.org/spec/core/core-schema.xml as of this

I suppose this will fall in Stian's volunteer effort, because  the
formal semantics of "The subject and object resources of the
oa:equivalent relationship represent the same Annotation"  will
require  some notion of "same" for instances, e.g. owl:sameAs.   At
the moment, it is unclear to me how one can specify formal semantics
that would restrict oa:equivalent to its intended use, i.e. where
Target and Body have identical URIs, which is what Figure 2.4 of the
core spec seems to be suggesting.
