RBAC (Role-Based Access Control)

The authorization decisions are handled by a system that enables administrators to configure access policies in real-time via the Kubernetes API. This system uses Role-Based Access Control (RBAC), which consists of roles defining permission rules and role bindings that grant those permissions to specific users or groups.

RDF Schema

A data-modeling vocabulary for RDF data that extends the basic RDF vocabulary.

Reconfiguration

Adjustments or modifications may be made to the production system during production in response to new requirements.

Relationship Manager

A specific point of contact assigned by the Data Spaces Support Centre to a data space initiative or another member of the Community of Practice.

Replica Set

A Replica Set is responsible for ensuring that a specific number of replica Pods are always running in a Kubernetes cluster. Other workload objects, such as Deployments, utilize ReplicaSets to maintain the desired number of Pods according to the ReplicaSet's configuration specifications.

ReplicationController

A ReplicationController is a workload resource that oversees a replicated application and guarantees that a certain number of Pod instances are continuously running. The Kubernetes control plane monitors and manages the desired number of Pods, even in situations where some Pods fail, or when Pods are deleted manually or inadvertently started in excess. Note that ReplicationController is now considered deprecated and replaced by the Deployment object, which provides similar functionality.

Resiliency

The concept of data resilience encompasses various aspects, including ensuring the continuous availability of production data hosted on data infrastructure, mitigating unexpected disruptions, and implementing effective governance, operational, and technical measures to safeguard data integrity.

Resource

A Resource is an internal component that cannot be directly ordered, but is used to construct Service Offerings. Unlike an Asset, it has endpoints. Key attributes of a Resource include its physical location, Autonomous System Number, network segment, and jurisdiction affiliations.

Resource Description Framework (RDF)

RDF, which stands for Resource Description Framework, is a widely used standard model for data exchange on the Web. One of the key features of RDF is its ability to merge data from different sources, even when the underlying schemas differ. Additionally, RDF is designed to allow for the evolution of schemas over time without requiring updates to all data consumers.

Resource Owner

The term Resource Owner refers to a natural or legal person who holds the rights to Resources to be provided by a Provider in compliance with Gaia-X regulations. Since Resources can be bundled into a Service Offering and nested Resource compositions are possible, there may not be a separate Resource Owner.

Resource Quotas

Resource Quota is a Kubernetes feature that allows you to specify constraints on the collective resource usage of a Namespace. It imposes limitations on both the number of objects that can be created in a Namespace based on their type, as well as the total amount of computational resources that can be consumed by resources within that Namespace.

Resources

In general, this term refers to the goods and objects within the Gaia-X Ecosystem. See also the term "Resource".

REST

The Catalogue's primary external interface for user interaction is the REST API.

Reviewer

A code reviewer is an individual who examines a specific portion of a project's codebase for accuracy and quality. Reviewers possess expertise in both the software engineering principles and the codebase itself. The reviewer status is typically limited to a particular segment of the codebase.

Rule Management

Business rules management (BRM) refers to the management and automation of business rules with the aim of enhancing organizational agility and responsiveness. BRM achieves this goal by automating decision-making processes, thus increasing the efficiency of business operations. By doing so, it reduces the reliance on IT departments to make changes to business logic. BRM also accelerates business process management (BPM) and service-oriented architecture (SOA) initiatives, while simultaneously improving decision management and dynamic case management efforts.
