The files in this directory are mostly (proposals for) agrements, in various stages of being adapted.

The current MetaModel is described (with diagram) here and given in the MetaModel.py file. The most precise description of the modeling rules is in the MetaModel checkValid functions (correct by definition). In words, the most reliable description is in the MetaModel.py header comment.

The special rules for storing the model inside ObjectDomain are given in the header comment of the ObjectDomain script

Data XML I/O is discussed in XmlGen.py (tag names, general rules). For more information on this subject see in the 'Run time behaviour' folder.

The principles behind the implementation may well be explained better in the other files in this directory.
