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/DigitalDocument (100% interoperability with search engines, web indexers, and general AI reasoning)
  • Specialized Domain Standard: http://open-services.net/ns/rm#Requirement (de facto standard for domain-specific ALM, BDD, or infrastructure operations)
  • Canonical Reference: http://open-services.net/ns/rm#Requirement
  • Agent Guidelines: When autonomous agents generate, expand, or validate instances of robos:GherkinFeature, 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

Gherkin Feature robos:GherkinFeature
