How does it work?
openMDM is a systems building block for the management of measurement data with the aim of optimising how the measurement data is used. As it has evolved, it has been used for very diverse technical disciplines.
The elements shared by all of these application cases are reflected in the openMDM standard process (work flow), which covers the operating steps of a complete measurement process, from the measurement planning stage right through to the use of the test results. The theory behind the standard process is the gradual build-up of the openMDM data structure as defined in the openMDM applications model.
Alongside the storage of the measurement data, the recording of descriptive data (metadata) is a central aspect in each operating step. Metadata are important for the usability of any data management system since they are used for classification by topic, for navigation, exploration, searches and for the ability to compare the measurement data.
The diagram illustrates the openMDM standard process. The process consists of several process steps and begins with “Plan test” as the starting point. Roles are assigned to the actions that occur in the process steps. Roles must be completed by the users, in which both several roles per user as well as several users per role can be specified (so-called role concept). Roles can also be undertaken by external companies, such as testing service providers.
Some process steps generate business objects which are intended for the user to see. These can include test orders, test results, reports, evaluations or references to data objects located in the ODS storage.
The administrative process steps (Maintain Methods, Maintain Test Data), or roles, occupy a special position. They can be undertaken by selected users only and are not accessible for the normal user.
