The element equate declares an ad hoc equivalence between works or @n values.

This is useful for handling sources that have not used the the same <IRI>s in defining works that you believe to be equivalent, or for associating values of @n that should be treated as synonymous.

Equating is transitive and greedy. If work A is defined with <IRI> X, work B with <IRI>s X and Y, and work C with only <IRI> Y, then works A and C will be automatically equated.

This element does not imply that the works are necessarily one and the same, or than the @n values are the same. It merely states that, for the purposes of this alignment, they should be treated as equivalent.
