Glossary

Both an API proxy and API gateway provide access to your backend services. An API gateway can even act as a simple API proxy. However, an API gateway has a more robust set of features — especially around security and monitoring — than an API proxy.

The BOM is a list of parts and materials needed to make a product, and, without it, manufacturing would be impossible. But the BOM is only part of the product equation. It shows “what” to make, not “how” to manufacture it, leaving the rest up to the BOP.

A standardized and unique ID for every company in the Catena-X ecosystem. This is assigned by the operating company upon registration.

Intermediary providing clearing and settlement services for all financial and data exchange transactions within the International Data Space.

Part of the product life cycle that includes all emissions upstream of production and all emissions generated by processes within the company until the product leaves the supplier's gate.

Data Sovereignty can be defined as a natural person’s or corporate entity’s capability of being entirely self-determined with regard to its data.

The DT is a virtual representation of assets and has the following characteristics:

- The DT has at least one Catena-X-wide unique ID.
- Digital Twins are organised according to a number of aspects. The set can be extended for life.
- An aspect of a DT includes both structural and behavioural data and models (including operational and simulation models).
- The semantics of an aspect can be described by semantic models.
- A single aspect can be linked to different heterogeneous data sources (including behavioural models).
- The DT can represent asset types (e.g. virtual prototype of a car) and asset instances (e.g. real car).
- A DT can cover the entire life cycle of an asset (e.g. planning phase, production, sale, utilisation and decommissioning phase). In practice, however, there may be more than one twin with different IDs representing different life cycle phases (e.g. one twin for types and several twins for instances).
- An asset can have more than one DT.
- The DT represents currently available information about an asset (synchronised with a certain frequency and accuracy) that can be used for simulation and business process integration.

By using aspects, the DT can refer to other DTs to express "part of" or "consists of" relationships.

Indirect greenhouse gas emissions that occur in the value chain downstream of the processes that the reporting company itself operates or controls.

Foss First is an Architecture Principle for Catena-X shared service.

A gaseous component of the atmosphere, both natural and anthropogenic, that absorbs and emits radiation at specific wavelengths within the spectrum of infrared radiation emitted by the Earth's surface, atmosphere and clouds.

IDS provide an architecture for sovereign data exchange across companies. It consists of Dataspace Connectors, Broker, Clearingservice and several other components. It's a fundamental FOSS-service of Catena-X.

The management shell equips all physical and non-physical assets (assets) with a cross-manufacturer, interoperable and standardized digital twin. Thanks to the uniform form and semantics of the management shell, the digital twin will thus be usable across company borders and will accompany an asset over the entire life cycle in the future.

Data relating to a specific product or activity within a company's value chain. This data can take the form of activity data, emissions or emission factors. Primary data is site-specific, company-specific (if there are several sites for the same product) or supply chain-specific.
