During the Product Development Process domain-specific modelsand the increasingly use of Engineering services result in a growingnumber of mainly heterogeneous and scattered datasets. In theOperational Phase of the product life cycle the more complex andsmarter products also provide a rapidly growing volume of date,stored in heterogeneous and scattered datasets, too. Efforts innetworking and machine communication intensify this ubiquitousprogress. A comprehensive management of product and machinedata does not exist. Machine manufacturers and machine operatorsare not able to share information consistently with instant access.Thus, machine manufacturers are out of reach of the machine life.Machine operators cannot request information from the product modelas well as the latest development results and especially changes.This circumstance is becoming problematic within the constraints ofnetworked machines and products. In this context, on the one hand,adequate product properties and behaviour are challenging tocompletely modeled because of the dynamic and event-basedcommunication between individual machines and machinecomponents of such cyber-physical systems. On the other hand, inparticular organizational shortcomings prevent a coordinated,multidirectional and reproducible information exchange. Thestrategies of product lifecycle management need to be enhanced bythe integration of machine data. Development engineers, servicetechnicians, machinery and other actors or objects out of the ProductDevelopment and Operational Phase gain a common database. Theproposed project provides the fundamentals for a federatedinformation system by means of an integration layer that manage a socalled Field Model, especially for machines. An anchored FieldMapping Schema is associated to the data structures of the differentdatasets from the Product Development and Operational Phase.Adapted processes realize the exchange of information betweendifferent users of the integration layer, based on the Field Model. Inaddition, an Field Event Memory store machine-specific information ofthe Operational Phase.
