In terms of a triple, such as "S P O". I created a Reification, and want
to create another triple for it；
The example is to record the appearance time of the triple:

It's a lot easier if you provide a complete, minimal example.
Property apearAmount = model.CreateProperty(NS+"apearTimes");
ReifiedStatement reiStmt = model.createStatement(sub, pro,
obj).createReifiedStatement();
reiStmt.addProperty(appearAmount, "23");
-----------------------------
Next time, when I create the same reiStmt, I can not get the corresponding
property.
Can anyone help me? Thanks in advance~
That code does not add the statement to the model - it simply creates it:
Statement stmt = model.createStatement(sub, pro, obj) ;
model.add(stmt) ;
ReifiedStatement reiStmt = stmt.createReifiedStatement();
