-There are three different levels of abstractions to model programs, collectively called abstract-level models:+There are four different levels of abstractions to model programs, collectively called abstract-level models:
  
     * A ''​ICodeLevelModel''​ represents the "​raw"​ model of a program, including only data directly extractable from the program source representation (Java bytecodes, Java source code, C/C++ source code...);     * A ''​ICodeLevelModel''​ represents the "​raw"​ model of a program, including only data directly extractable from the program source representation (Java bytecodes, Java source code, C/C++ source code...);

-===== ''​getName()'' ​and ''​getPath()''​ Methods ​=====+===== Names and Paths =====
  
-Although the getID(), getName(), and getPath() methods form a trio, they have different semantics. The getID() must return a unique identifier for each constituent in a model. ​The getName() returns the name of a constituent. For binary class relationships and method invocations,​ the name returned by getName() is less important, it could simply be Method Invocation, for example. ​(Their ID must still be unique, though.)+The ''​getName()''​ always ​returns the simple ​name of a constituent. For binary-class relationships and method invocations,​ the name returned by ''​getName()'' ​is less important, it could simply be ''​Method Invocation''​, for example. ​For a first-class entity, though, it is important, for example ''​getName()''​ returns ''​IConstituent''​ for ''​padl.kernel.IConstituent''​. Here are other examples of ''​getName()''​ values:
  
-Here are some examples of getID() :+    * ''​padl''​ for a package;
  
-    * padl for a package;+    * ''​getName()'' ​for a method;
  
-    * getName() for a method;+    * ''​setName(char[])'' ​for a method;
  
-    * setName(java.lang.String) ​for a method;+    * ''​name'' ​for an attribute;
  
-    * addA(int, padl.example.aggregation.A) ​for a method;+    * ''​NaturalOrderComparator'' ​for a member class.
  
-    * name for an attribute.+The paths are used to name and address each constituent uniquely within a model but consistently across modelsThe paths start with a '/'​ and the name of the model. Then, it includes the name, as in ''​getName()'',​ of each constituent to go through until the name of the current constituent is reached. Here are some examples of ''​getPath()''​ values:
  
-    * Member ​for a member class, member interface, or member ghost.+    * ''/​PADL|padl'' ​for a package;
  
-Here are some examples of getName() ​:+    * ''/​PADL|padl|kernel|padl.kernel.IConstituent|getName()''​ for a method;
  
-    * padl for a package;+    * ''/​PADL|padl|kernel|padl.kernel.IConstituent|setName(char[])'' ​for a method;
  
-    * getName ​for a method;+    * ''/​PADL|padl|kernel|impl|padl.kernel.impl.Constituent|name'' ​for an attribute;
  
-    * setName ​for a method;+    * ''/​PADL|padl|kernel|impl|padl.kernel.impl.GenericContainerOfNaturallyOrderedConstituents$NaturalOrderComparator'' ​for a member class.
  
-    * addA for a method; +The class ''​padl.path.Finder'' ​in the ''​PADL'' ​project ​can be used to walk the paths.
- +
-    * name for an attribute. +
- +
-    * Member for a member ​class, member interface, or member ghost. +
- +
-The paths are used to represent how to get to a constituent within a model. +
- +
-The paths start with a '/' ​and the name of the model (optional). +
- +
-Then, each constituent to go through until the target is specified the same way: +
- +
-   - the '​|'​ character,​ +
-   - the (simple) name of the interface in padl.kernel of the constituent (or one of its super-interface,​ but always in padl.kernel), +
-   - the ':' ​character,​ +
-   - a constituent specific part: +
-     * If the constituent is an Operation, its name, a '(', the list of the TypeName of the types of its arguments separated by a ',' ​(if any), a '​)'​ +
-     * Its name otherwise +
- +
-The class padl.path.Finder ​can be used to walk the paths.+
