{{UMM|* The descriptive model consists of '''MetaClasses''' and '''MetaProperties''' and relations between these objects.* Each MetaClass is defined by** a collection of MetaProperties** the line of inheritance** classification information

 Each MetaClass is defined by* a collection of MetaProperties* the line of inheritance* classification information  A MetaProperty implements different features and settings.  * In this MetaModel we explicitely distinguish between the description (structure, relations,…) and '''instances''' (actual occurences) of data objects  * The MetaClasses might be on an equal hierarchy level from the descriptive point of view, whereas the instances are then related using '''references''' and '''relations'''}}
