11		-== Overview ==
12		-
13		-
14		-
15		-This subproject provides a tracing mechanism for arbitary model-elements across multiple model transformations, based on EMF.
16		-
17		-The main propose of KTM is to allow information transfer between abstract models and their resultant transformed models.
18		-

21		-== Transformation Tree Model ==
22		-
23		-
24		-
25		-To offer a mapping between model-elements during multiple transformations KTM introduces a model called TransformationTree to represent these relations.
26		-
27		-It is based on an EMF-Metamodel.
28		-
29		-
30		-
31		-<metamodel>
32		-
33		-
34		-
35		-The structure of the model can be separated into two parts.
36		-
37		-First part is a tree of transformations.
38		-
39		-Each Model-Class is a representation of a concrete model which is transformed. So models are nodes and ModelTransformations are edges.
40		-
41		-Thus the Model representing the root-model of a tree is also the root of a concrete TransformationTree-Model.
42		-
43		-Second part is object mapping.
44		-
45		-Concrete models contain EObjects as their elements, which are representend by Element-Class in TransformationTree metamodel.
46		-
47		-The Elements of two models are connected with ElementTransformations-Class to model their
48		-
49		-origination relationship in corresponding model transformation.
50		-

53		-An abstract example of an instance of this model:

61		-== Extensions ==
62		-
63		-
64		-
65		-Two classes are provided by this project to extend functionality of the core model.
66		-
67		-
68		-
69		-TransformationMapping (JavaDoc)
70		-
71		-
72		-
73		-The main propose of this class is generation of a Object mapping during transformation process.
74		-
75		-Therefor it provides different functions for incremental registering of single parent child relations beween EObjects.
76		-
77		-Furthermore, the extension allows to extract the mapping and check completeness of mapped elements against content of transformed models.
78		-
79		-
80		-
81		-TransformationTreeExtensions (JavaDoc)
82		-
83		-
84		-
85		-This class proived all functionalities to easily traverse and search in a TransformationTree.
86		-
87		-Furthermore, it allows to modify trees by creating, deleting or appending new transformations and transformed models.
88		-

92		-
93		-
94		-
95		-== Implementation Details ==
96		-
97		-
98		-
99		-All references to EObjects are references to a copy of the original EObject. This allows to represent immutable mapping. To reidentify corresponding EObjects TransformationTreeExtensions provides search funtions and matching functionality.
100		-
101		-
102		-
103		-Models in TransformationTrees may be transient.
104		-
105		-This indicates that all references to EObjects in all Elements of the transient model are removed.
106		-
107		-Thus these models can't be source of a new appended tranformation and can not be associated with it's orginal model.
108		-
109		-The main propose of this feature is to improve scalability of TransformationTrees by removing unneccessary references to internal model, but preserve traversing funtionality of the ObjectMapping.
