Subset: RelationalModelProfile

A profile that includes all the metamodel elements whose semantics can be expressed using the classic Relational Model.

The Relational Model excludes collections (multivalued slots) as first class entities. Instead, these must be

mapped to backreferences

__

The classic Relational Model excludes inheritance and polymorphism -- these must be rolled down to

concrete classes or otherwise transformed.

A collection of definitions that make up a schema or a data model.

an element whose instances are complex objects that may have slot-value assignments

an element whose instances must be drawn from a specified set of permissible values

a collection of slots whose values uniquely identify an instance of a class

Slot	Description
name	the unique name of the element within the context of the schema
classes	An index to the collection of all class definitions in the schema
identifier	True means that the key slot(s) uniquely identifies the elements
required	true means that the slot must be present in instances of the class definition
attributes	Inline definition of slots
unique_keys	A collection of named unique keys for this class
unique_key_name	name of the unique key
unique_key_slots	list of slot names that form a key
range	defines the type of the object of the slot
key	True means that the key slot(s) uniquely identify the elements within a singl...
