obsolete_has_position_component true A relation linking a sequence feature to its component Position that represents an identifying criteria for sequence feature instances. For representing positional data, we advocate use of the FALDO model, which links to positional information through an instance of a Region class that represents the mapping of the feature onto some reference sequence. The positional_component property in GENO is meant primarily to formalize the identity criteria or sequence features and qualified sequence features, to illustrate the distinction between them.
