Performance Model Interchange Format (PMIF 2): A comprehensive approach to Queueing Network Model interoperability

The Performance Model Interchange Format (PMIF) provides a mechanism for transferring the system model information among performance modeling tools requiring only that the tools either internally support PMIF or provide an interface that reads/writes model specifications from/to a file. This paper presents the latest version of the specification (PMIF 2): a metamodel defining the information requirements and the corresponding XML schema. It defines the semantic properties for a pmif.xml interchange, the prescribed validation order, errors and warnings, and a tool and Web service implementation. Import and export prototypes for two different types of tools prove the concept. Generally available examples are used for repeatability.
