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/Service (100% interoperability with search engines, web indexers, and general AI reasoning)
  • Specialized Domain Standard: https://kubernetes.io/docs/concepts/services-networking/service/ (de facto standard for domain-specific ALM, BDD, or infrastructure operations)
  • Canonical Reference: https://schema.org/Service
  • Agent Guidelines: When autonomous agents generate, expand, or validate instances of robos:KubernetesService, 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 Service robos:KubernetesService

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

const { OSLCGraphParser, OSLC_CONTEXT } = require('/usr/local/share/robos/robos-graph/lib/oslc-parser');

const validator = new SHACLValidator();
