What is openMDM?

openMDM is an open-source, freely configurable and expandable software building block for the management of measurement data. Based on open standards and open interfaces, its other key features include high reusability, flexible expandability and universal usability.

Using the openMDM building block, company data management systems, differing in form and function, can be configured to offer professional management of measurement data, evaluation results and their descriptions (metadata). New systems can be constructed from existing openMDM blocks (components). Thus, the ability to reuse over and over again plus configurability reduce the cost of programming.

The core task undertaken by openMDM is the optimisation of logistics, and the management and use of measurement data. It acts as a central data hub. Applications to record and evaluate measurement data are linked via interfaces.

openMDM is able to describe measurement data with full syntax and completely semantically. This is made possible by employing ASAM ODS to standardise data storage. This creates the potential to merge and compare measurement data from different contexts. Data can be exchanged between all ODS-compatible applications without the need for conversion. Converters and import/export filters do not need to be developed any longer for each tool in the tool chain. Furthermore, ASAM ODS fulfils the requirements for an archiving format: You will still be able to interpret ODS data in 30 years’ time!


openMDM is the open branch of the measurement data management system “MDM” developed by Audi. The openMDM community is busy with further developments and extensions to openMDM. It is being used to exchange new components as well as acting as an information and communications platform for members.
