| 87 | | 4. the "#isParalogOf" property is symmetric (symmetry is an OWL logical function), meaning that if X is a paralog of Y, then Y is also a paralog of X. Note also that, in this case, I am defining the #isParalogOf property in my service ontology; however '''THIS IS NOT ALWAYS NECESSARY''' - if you produce data that represents a relationship that has been adequately defined by someone else, then you are free to use that third-party's predicate and you don't need to define it yourself! Re-use re-use re-use!! That's what the Semantic Web is all about! ...in fact, the Semantic Web works BETTER if we all look for, and re-use predicates that have been defined by someone else!! |
