Architectural Layers for Standards

The document discusses standards and interoperability across different architectural layers of business processes. It notes that at the business layer, the goal of interoperability is to automate processes and reduce risks through standardized processes. At the application layer, key issues are standards for information transfer using XML and application-specific schemas. The infrastructure layer needs standards to allow the layer to remain interoperable and support higher layers, even with changes like the transition to IPv6.
