Sometimes it is more convenient to use an inverse property rather than direct property. E.g. the realization of a fabio:ResearchPaper is a fabio:JournalArticle, but it may be more convenient to talk about the article as a realization of the paper. This is why we explicitly define frbr:realization as the inverse of frbr:realizationOf.
