“soon”: See also, the second coming of Christ.

#6

I have been reading about Graph databases and Triplestores. Am I getting this correct?

  • node = vertex = entity = point = subject/object
  • edge = graph = relationship = arc/line/arrow = predicate
  • properties = labels (metadata on nodes and edges)

#7

Subject/Object is usually a “node”, but it might be an “edge” or “predicate”. In RDF stores predicates are vertices as well.
Also, Subject/Object pair usually means Source/Target of a relation.

Label is not exactly a metadata on Nodes/Egdes, it’s more like a subgraph label for a relation. It can be used in queries to filter out different data sources, for example.


#8

What is an “inbound predicate”? How about inbound vs. outbound predicates?

Found the terms here and can’t really find a good definition.
