[yongjun1]

-XCore

1. intrinsic features
2. classification level defined for each class
3. „is core“ to relax confusion caused by extensive use of multiple inheritance

-Tools

1. support for searching, e.g.
2. classes that implement a certain method
3. methods that send certain messages
4. class with name (similar)
5. support for refactoring
6. support for protecting referential integrity

-XModler

1. attributes typed with classes
2. Currently not possible in standard dialog
3. representation of intrinsic features
4. selection of generalisation level
5. quick swapping between class and instance representation
6. support for propagating attribute interface to corresponding class
7. support for navigating between models
8. extended browser
9. classification level of classes indicated through colours
10. support for multi-level editors
    -show metaclass of class in diagram
11. associations
    -reading direction
    -more convenient specification of multiplicities
    -no enforcement of references (bi- unidirectional)
    -intrinsic associations

-XTools

1. persistence
2. multi-level editors
3. convenient reuse of notations
4. enable loading SVG
5. composed symbols

-Performance
the old version is slower than EMF

-Further Aspects

1. GUI Design
   -integration of canvas tool
2. Generating GUIs from models
   -assign default widget to class/operation
   -generate (context-specific) GUI
   -allow for modifying generated GUI
