Reviews run for a minimum of one week. The outcome of the review is decided on this date. This is the last day to make comments or ask questions about this review.
openMDM® is described as "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 re-usability, flexible expandability and universal usability".
openMDM® uses a data storage system that complies with the Open Data Services (ODS) standard of the Association for Standardization of Automation and Measuring Systems e.V. (ASAM). ASAM is an organization which was set up by German car manufacturers to standardize data models and interfaces for simulation, measurement and evaluation systems. ODS thereby ensures compatibility of data across different platforms and tools by specifying a consistent format.
The MDM|BL project covers the basic framework to build an application to work with openMDM data based on the ASAM ODS standard. Furthermore it defines the specification of the openMDM business objects and how they are implemented within the ASAM ODS standard.
This Project is part of the Open-Measured-Data-Management-WG
The MDM|BL comprises a bottom to top architecture view of three parts.
The first one is a specific openMDM application model definition for the ASAM ODS data storage. The standardization provides a structured representation for common use case related data in all openMDM application. The data model is split into the base model, which covers the most common use cases, and extensions for additional use cases.
The base model and every extension has an associated API interface. These interfaces are used by higher level components to work with openMDM business objects. In addition there are a set of business interfaces, which represent non data based enterprise use cases.
At the top of the layer there are the implementations of the business interfaces. In consideration of the API there normally will be an ODS server implementation but in some use cases the data storage is implemented otherwise. Virtual objects or the storage in an ODS ATFX file are examples.
Concerning the runtime view the business layer project defines a core application structure, which every openMDM application is based on. This structure is composed of services and rules how these services should be used and be executed at runtime.
With the migration to open source development, the core functionality for measured data management solutions can be reused for different applications. Instead of expensive isolated solutions, new solutions can rely on the common framework.
We hope to encourage other manufacturers in the automotive industry to adopt the ODS standard for structured data management and to popularize our solution to other industries.
ASAM ODS Corba Interface. The ASAM ODS CORBA interface is a IDL Definition of the ASAM ODS OO-API. This is the ASAM ODS specification for storing and retrieving measurement data form the ODS server
The MDM|BL software cannot be used standalone. Data is read from and written to an ODS server which has to be acquired and licensed separately.
