One advantage of a graph database implementation over a traditional wiki implementation is in regard to querying along edges as opposed to following links. Which is to say that the edges of a graph database will tend to have richer semantics than a wiki&#x27;s generic hyperlinks [but it is not to say that a graph database is necessarily better].<p>To put it another way, at best a link from a wiki page gets implied importance based on it&#x27;s position within a document. A graph database edge can have many properties including &quot;weight&quot; or &quot;relevance&quot;. Of course these could be added to wiki markup as properties, but there is a point at which the right tool is better than layered make-do&#x27;s.
