The Architecture of Interoperable Information Systems (AIOS) represents a means for the comprehensive description of loosely coupled, interoperating information systems and for the systematic, model-based enactment of collaborative business processes. To this aim, it combinesbuilds conceptson fromthree theorthogonal areasaxes: ofEnterprise enterprise modelingDimensions, collaborativeColloborative businessViews and Service-orientedLevels Computingof technical Granularity. At the core of the architecture lies the Business Interoperability Interface, which describes the information system boundaries of one organization to its collaboration Partners and connects internal and external information systems.

<br />

The AIOS builds on three orthogonal axes: Enterprise Dimensions, Colloborative Views and Levels of technical Granularity.

=== Enterprise dimensions===

Line 30 ⟶ 29:

# Business Level: Here the processes to be automated are described from a technique independent level. In MDA this level is referred to as CIM level.

# Technical Level: Here the IT concept is described. Therefore, the models from the first level are technically enriched, for example, instead of business functions now components are described, but still on a coarse-grained, conceptual level. Since the models on the second level represent the basis for an automated generation of executable code, they might have to be further adapted to fit implementation level constraints.

# Execution Level: Here the models are machine interpretable and can used during runtime in the execution of processes.
