Machine-generated Data/ machine Data

Machine-generated data (MGD) refers to information generated by mechanical or digital devices. It commonly encompasses data produced by an organization's industrial control systems and mechanical devices specifically designed for performing a singular function. external-link


This pertains to the exchange of information among machines, such as between control units that manage business or operational processes, and sensors or actuators. external-link

Managed Service

A Managed Service refers to a software offering that is provided and maintained by a third-party provider. This can include a variety of services such as AWS EC2, Azure SQL Database, and GCP Pub/Sub, as well as other software offerings that can be utilized by an application. external-link

Management plane

One of the three levels of interoperability within Gaia-X is the Federated level, which is an extension of the common digital governance provided by the Federators of the relevant ecosystems. This level does not cover specific ecosystem governance rules as they are considered out of scope for Gaia-X. external-link


A Kubernetes manifest is a description of a Kubernetes API object in YAML or JSON format that specifies the desired state of the object. When a manifest is applied to a Kubernetes cluster, Kubernetes will ensure that the actual state of the object matches the desired state specified in the manifest. A single configuration file can contain multiple manifests for different Kubernetes objects. external-link


On the Internet, the term "Mashup" describes the creation of new content by integrating and processing existing content. Originally, the term comes from music. There are various software technologies for this kind of creative work. external-link

Massive Open Online Courses

MOOCs are online courses that have a theoretically unlimited number of participants. They use a combination of traditional knowledge delivery methods such as videos and reading materials, as well as interactive forums where instructors and learners can collaborate and build communities. external-link

Mean Time Between Failures

Mean Time Between Failures (MTBF) describes the expected amount of time a system, facility, or system component can spend in normal operation before a failure occurs. external-link

Medical Sensor Platforms

A central data hub or marketplace for sensor data from various medical applications enables the integration and improved availability of information. external-link


A Kubernetes community member who makes continuous contributions to the project. These members may be assigned issues and pull requests (PRs) to work on, participate in special interest groups (SIGs) through GitHub teams, and have their PRs automatically run through pre-submit tests. To maintain membership status, a member is expected to continue actively contributing to the community. external-link


The central data management of smart metering is called MDM. It is essential for processing the recorded consumption data. external-link

Metering point

In the energy industry, the term "metering point" refers to the location where the energy supplier provides its supply services to the consumer. This location is represented by a meter or a group of metering points. Each metering point is given a standardized description and a metering point number. external-link


A non-invasive method for creating narrow trenches or slots (with a width of 4 cm to 20 cm) through cutting or milling is used to install micro-ducts, micro-cables, or fiber optic cable routes. Initial experiences show that micro and mini trenching can reduce civil engineering costs for broadband expansion in the respective deployment areas by approximately one-fourth to one-third. external-link


Minikube is a tool that enables users to run Kubernetes clusters locally on their machines. It sets up a single-node cluster within a virtual machine (VM) on the user's computer, allowing them to experiment and learn Kubernetes in a local environment. external-link

Minimal Viable Product

The term "Minimal Viable Product" is used in the context of Catena-X and the lean startup environment to refer to the first iteration of a product that is minimally functional, allowing the needs of customers and users to be learned. This is often in the form of a mock-up or demonstrator, which is different from the actual marketable product. The Minimal Viable Product is a basis for incremental improvement and was formerly known as the Catena-X Speedboat, which included the portal, shared services, and two business cases for circular economy and traceability.

Machine Learning Model Operationalization Management provides an end-to-end machine learning development process to design, build and manage reproducible, testable, and evolvable ML-powered software. external-link

Modal travel shift

The act of transitioning from one mode of transportation to another, often with the aim of reducing environmental impact or enhancing efficiency. external-link

Model (in machine learning)

In the realm of machine learning, a model is a conceptualization of real-world phenomena that has been simplified for practical purposes. By utilizing a learning algorithm, a statistical model can be optimized to generalize the training data. The model, in turn, can be utilized to process new data and calculate a function. Decision trees, regression curves, and artificial neural networks are all examples of popular model types. external-link


Breaking down a system into modules with minimal interdependence is recommended. This means that each module should be self-contained and provide certain predefined skills, which can be hierarchically ordered. This allows for greater flexibility in making changes to the system and easier maintenance over time.

Motion Data

Motion Data provides geo-information-based analytics obtained from anonymized signaling data from the mobile network of Deutsche Telekom. Based on these insights, there can be multiple use cases developed around user activity movement and can assist businesses to take informed strategic decisions. external-link


Information that provides the average time between two failures or outages (MTBF - Mean Time Between Failures). external-link

Multi-Channel Learning Environments

A teacher provides digital teaching-learning content that can be used in an Internet-based environment for education and qualification. The learner has the option of using the content via various channels and end devices, including desktop PCs, laptops, smartphones, tablet PCs, wearables, and IPTV. external-link

Multi-cloud environement

A multi-cloud strategy involves utilizing two or more cloud computing services, and a multi-cloud deployment typically refers to a combination of public infrastructure as a service (IaaS) environments, such as Amazon Web Services and Microsoft Azure. However, it can also encompass multiple software as a service (SaaS) or platform as a service (PaaS) cloud offerings. external-link

Multidimensional Expressions

MDX, which stands for Multidimensional Expressions, is a database language designed for analytical problem-solving. It serves as an extension to the SQL language, introduced by Microsoft to enable querying and scripting access to multidimensional data. While MDX is known for its flexibility, it can be considered relatively complex. Nevertheless, its extensive flexibility allows for the implementation of all essential solution scenarios in traditional data warehousing. external-link

Multifunctional participation platforms

Citizens and companies have the opportunity to actively participate in planning and decision-making processes at various federal levels with the help of multifunctional participation platforms. These platforms enable cross-thematic and cross-administrative involvement. external-link

Multimedia database management systems

Specialized databases that are designed to process multimedia content are called multimedia databases. The retrieval of media objects based on their characteristics, also known as features, plays a significant role. This search process for multimedia content is called multimedia retrieval. external-link
