I try to outline my domain.
Simple implementation of an UML informationflow:
(a:Class)-[:InformationFlow]->(b:Class)
Conveyed items can be attached to the InformationFlow:
[:InformationFlow {items: [..] }
But in our model InformationItems are really "first-class-citizens". A lot
of searches are related to this items. So I want them to be part of the
graph and queryable. My current approach is to add them as nodes. But
because there can also InformationFlows without or with more than one
conveyed items, I create an "abstract" one first:
(a:Class)-[:InformationFlow]->(:InformationItemAbstract)-[:InformationFlow]->(b:Class)
Now I can attach as many real InformationItems to the abstract one as I
like:
(:InformationItemAbstract)-->(x:InformationItem {..})
(:InformationItemAbstract)-->(y:InformationItem {..})
Now I can search for InformationItems:
MATCH (:InformationItem
{name:'IE1'})<--(a:InformationItemAbstract)-[:InformationFlow]-(b:Class)
RETURN a,b
The question: Is there a better approach?
