7 Enterprise Viewpoint
Note: The enterprise viewpoint into a service architecture concerns itself largely with the context of that architecture: the business models, policies, and organizational structures
within which the architecture will be implemented. Another means of expressing the enterprise viewpoint is through use cases and derived requirements for the functionality
to be supported through the architecture. In the case of OWS 1.2, those use cases and requirements were initially developed in an architectural requirements document and are
now largely contained in individual IPRs for the principal activity areas of the initiative.
7.1 The OpenGIS Web Service Framework in the Enterprise
The OpenGIS Web Services Framework provides a common set of interfaces and encodings that span the functional parts of the enterprise shown in Figure 5 to provide
enterprise-wide interoperability. The enterprise depicted is comprised of users and customers, networks and communities of geospatial services and data holdings
representing real world features and phenomena. Network resources are published for broader use within and between communites. Applications discover, access and interact
with network resources through simple request-response interactions.

Multi -Source Environment
Figure 6 System Concept: Multi-source information operations
Figure 6 depicts the OWS1.2 system concept representing a typical information production environment where the OpenGIS Services Framework is the basis for
enterprise-wide interoperability. There are six main functional parts to this production environment:
• Common Source Processing – where all source acquisition, assessment and
processing occurs •
Feature Production – where feature production and management occurs •
Imagery Production – where imagery production and management occurs •
Other Information Production – where multi-source processing and specialized information production and management occurs
• Common Product Processing – the main product finishing and distribution
capability
