Common Manipulation of Objects

You move to an object because you want to manipulate it. You can get or set a property, delete an object, delete a relationship between two objects, or add a relationship between two objects. The software bug-reporting example illustrates some common manipulations:

• Get a property — retrieve a bug's description for filling out a bug report.
  
  
• Set a property — change a bug's priority from Moderate to Urgent.
  
  
• Delete an object — delete a new bug because it replicates an already reported bug.
  
  
• Delete an object — disassociate a program from a bug when an employee associates a bug with a program before the bug has been accurately diagnosed.
  
  
• Add a relationship between two objects — associate an existing but previously undiagnosed bug with a program.
