title: Why does Grakn use noun semantics on relations instead of verbs?
body: <p>I was going over some of the docs <a href="https://dev.grakn.ai/docs/examples/phone-calls-schema#the-schema" rel="nofollow noreferrer">here</a>.</p>
  
  <p>I was curious why Grakn opts to indicate relations using noun semantics rather than verb semantics? In most of the other graph work and research I’ve covered, it usually makes sense to think that two entities (nouns) are linked by a verb e.g. <code>person worked at company</code>. Indeed, for a few entities that I am dealing with, it is a bit difficult to reason about the relationships as nouns for example if <code>artist remixed track</code>.</p>
  
  <p>I’m inclined to use verbs as relations but I wonder if that is not how I should be thinking about it in a Grakn setup. Are there eventual difficulties I can expect to face if I decide to use verb semantics?</p>
