The meta class CrClass serves for a class of applications that mostly store information in the content repository and that use a few attributes adjoining this information. The class handles the open acs object_type creation and the automatic creation of the necessary tables based on instances of this meta-class.

The definition of new types is handled in the constructor of CrType through the method create_object_type, the removal of the object type is handled through the method drop_object_type (requires that all instances of this type are deleted).

Each content item can be retrieved either through the general method CrClass get_instance_from_db or through the "get_instance_from_db" method of every subclass of CrItem.

This Class is a meta-class providing methods for Classes managing CrItems.

Defined in packages/xotcl-core/tcl/cr-procs.tcl
