4.1.2 AAS metamodel overview ToC Previous Next

The AAS metamodel stipulates structural principles of the AAS in a formal manner (UML) in order to enable an exchange of information between AASs. The main parts of AAS model elements describe the represented asset as well as its submodels (see Figure 2). Optionally, dictionaries and views may be part of an AAS. A dictionary contains so-called concept descriptions. Views define a set of elements selected for a specific stakeholder, e.g. for a machine operator. An AAS represents exactly one asset.
