Detailed Description

An applicative document is an instance of a class inheriting CDM_Document. These documents have the following properties:

they can have references to other documents.
the modifications of a document are propagated to the referencing documents.
a document can be stored in different formats, with or without a persistent model.
the drivers for storing and retrieving documents are plugged in when necessary.
a document has a modification counter. This counter is incremented when the document is modified. When a document is stored, the current counter value is memorized as the last storage version of the document. A document is considered to be modified when the counter value is different from the storage version. Once the document is saved the storage version and the counter value are identical. The document is now not considered to be modified.
a reference is a link between two documents. A reference has two components: the "From Document" and the "To Document". When a reference is created, an identifier of the reference is generated. This identifier is unique in the scope of the From Document and is conserved during storage and retrieval. This means that the referenced document will be always accessible through this identifier.
a reference memorizes the counter value of the To Document when the reference is created. The From Document is considered to be up to date relative to the To Document when the reference counter value is equal to the To Document counter value.
retrieval of a document having references does not imply the retrieving of the referenced documents.
