From: Preserving sequence annotations across reference sequences
Semantic relationships between annotations. The sematic relationship between annotations is determined by the relationship between their reference sequences. 1) An annotation is the same as another annotation if their reference sequences represent the same biological entity. 2) An annotation is equivalent of another if its reference sequence is syntactic part of the other reference sequence. 3) An annotation is derived from another if it reference sequence is derived from the other reference sequence.
