Specification Metadata

Upstream Schema Basis (Refers From) & Global Standards Provenance

This RobOS schema is modeled after and directly aligns with two levels of global standards:

  • Universal Schema.org Class: https://schema.org/ComputerPlatform (100% interoperability with search engines, web indexers, and general AI reasoning)
  • Specialized Domain Standard: https://kubernetes.io/docs/concepts/overview/ (de facto standard for domain-specific ALM, BDD, or infrastructure operations)
  • Canonical Reference: https://schema.org/ComputerPlatform
  • Agent Guidelines: When autonomous agents generate, expand, or validate instances of robos:KubernetesCluster, they MUST adhere to and base their output on this referred schema object and universal Schema.org parent class, extending it with RobOS SDLC properties.

Entity Relationship & Schema Context

Kubernetes Cluster robos:KubernetesCluster

Governed by W3C SHACL shape urn:robos:shape:KubernetesClusterShape within the DevOps & Cloud (robos.devops) (robos.devops) package store.

Property Constraints & SHACL Rules

Property Path Name Multiplicity Data Type Constraint Rule / Validation Message
dcterms:title Title / Display Name 1..* xsd:string Kubernetes Cluster must have a title or display name.
robos:provider Backend Provider 1..* xsd:string Kubernetes Cluster must declare provider (eks, gke, aks, minikube, k3s, on-prem).
robos:apiEndpoint apiEndpoint 1..* xsd:string Kubernetes Cluster must specify API server endpoint URL.
robos:clusterContext clusterContext 1..* xsd:string Kubernetes Cluster must specify kubeconfig context name.
