public abstract class ImmortalGraph
extends BigdataGraph

An implementation of a Blueprints Graph that implements immortality using the RDR specification. Modeling vertices <<:v1 rdf:type :Vertex>> :timestamp "t1" . Modeling element properties <<:v1 :p1 "val1">> :timestamp "t1" . <<:v1 :p1 "val2">> :timestamp "t2" . Modeling edges Two distinct edges between :v and :v2 with the same edge label. Totally legal in Blueprints. :v1 :knows :v2 . <<:v1 :knows :v2>> :id :e1 . <<:v2 :knows :v2>> :id :e2 . Created at different times. :e1 :timestamp "t1" . :e2 :timestamp "t2" . With different properties. <<:e1 :p1 "foo">> :timestamp "t1" . <<:e2 :p1 "bar">> :timestamp "t2" . Modeling a deleted property: <<:v1 :p1 :null>> :timestamp "t3" . Multiple values for the same property with the same timestamp implies a list: <<:v2 :p2 "v1">> :timestamp "t1" . <<:v2 :p2 "v2">> :timestamp "t1" . <<:v2 :p2 "v3">> :timestamp "t1" . Pure append writes - no removal of old property values.
