== Structure ==
The static part of the architecture builds on three orthogonal axes: Enterprise Dimensions, Levels of technical Granularity and Colloborative Views.
 
=== Collaborative views ===
Similar to private, public and global views as known from business process and workflow modeling, in the AIOS, corresponding private, public and global views on information system elements are provided.
# The '''private view''' comprises the only internally visible information system elements.
# The '''public view''' acts as an interface to the internal, private system elements; it protects internal systems and enables interoperability without the need for a significant change to the internal systems. This public view describes the information system boundaries of an organization to its collaboration partners and connects internal and external information systems, thereby also providing the content of the [[Business Interoperability Interface]] of an organization.
# The '''global view''' can be used to correlate and connect the public views of different systems.
 
=== Enterprise dimensions ===
Line 31 ⟶ 37:
# In the '''function dimension''', business functions and services offered in the collaboration are described.
# In the '''process dimension''', the processes that each organization offers are described as well as how these public processes are related to adjacent processes of partner organizations.
Thus, in combination with the axis "collaborative views", *private, public and global views on processes, functions, data, and organizational roles* are provided.
