title: What is the difference between a relation and a property in a Linked Data ontology?
body: <p>The wikipedia article <a href="https://en.wikipedia.org/wiki/Ontology_components" rel="nofollow noreferrer">ontology components</a> describes relations as one of the components of an ontology.  It states that relations "specify how objects are related to other objects".  Is-a/sub-class and partOf relations are provided as examples.</p>
  
  <p>I am trying to understand the difference between a relation and a property/attribute.  For instance, dcterms:creator relates a book and its author.  Is it a relation or a property?  How do ontology description languages such as OWL differentiate this?  Is there a computational/logical difference between a relation and a property?</p>
  
  <p>Can we say that if a term links to another class or entity it is a relation and if it is a literal value, then it is a property/attribute?</p>
