Abstract

Die Erfindung betrifft ein Verfahren sowie ein System zur Definition von Strukturen von Objekt- und/oder Datenmodellen (OM), mit mindestens einem Schema (XS1, XS2) zur Beschreibung der Strukturen. Eine auf- und abwärtskompatible Schemaevolution wird dadurch erreicht, dass in einem ersten Attribut (10, 20) eines Schemas (XS1, XS2) eine Kennzeichnung einer Version des jeweiligen Schemas (XS1, XS2) erfolgt, wobei der im jeweiligen Schema (XS1, XS2) verwendete Namensraum (1) und die im jeweiligen Schema (XS1, XS2) verwendeten Typ- und Elementnamen (11a..14a, 21a..24a) unabhängig von der Version beibehalten werden, wobei Typen und Elemente (11..14, 21..24) nur unter Beibehaltung des Typ- bzw. Elementnamens (11a..14a, 21a..24a) erweitert werden und wobei in Schemata (XS2) einer neueren Version nicht erweiterte Typen und Elemente (21..24) unverändert von den jeweiligen in Schemata (XS1) einer älteren Version verwendeten Typen bzw. Elementen (11..14) übernommen werden.
