+class DataModel(dict):
+ """Provides tools for managing a data model.
+
+ When constructing a data model the CaosDB representation can easily be
+ created using the classes RecordType and Propery, storing them in a
+ Container and inserting it in CaoSDB. However, this has one drawback: You
+ cannot simply change someting and update the container. The container will
+ insist on having valid ids for all contained Entities.
+
+ This class allows you to define your model as easily but also provides you
+ with a method (`sync_data_model`) that will sync with the data model in an
+ existing CaosDB instance.
+
+ This is possible because entities, defined in this model, are identified
+ with entities in CaosDB using names. I.e. a RecordType "Experiment" in this
+ model will update an existing RecordType with name "Experiment" in CaosDB.
+ Thus, be carefull not to change existing Entities that were created for a
+ different purpose (e.g. someone else's experiment).
+
+ DataModel inherits from dict. The keys are always the names of the
+ entities. Thus you cannot have unnamed entities in your model.
+
+ Example:
+
+ # Create a DataModel with a RecordType and a Property, not assuming any
+ # relation between the two.
+ dm = DataModel([db.RecordType(name="myRecordType"),
+ db.Property(name="myProperty")])
+ # Sync the DataModel with the server, so that the server state is consistent
+ # with this DataModel's content.
+ dm.sync_data_model()
