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

Prompt Strategy robos:PromptStrategy

Governed by W3C SHACL shape urn:robos:shape:PromptStrategyShape within the Core Platform (robos.core) (robos.platform) package store.

dcterms:title robos:strategyType robos:engine

Property Constraints & SHACL Rules

Property Path Name Multiplicity Data Type Constraint Rule / Validation Message
dcterms:title Title / Display Name 1..* xsd:string Prompt Strategy must have a title or display name.
robos:strategyType strategyType 1..* xsd:string Prompt Strategy must declare strategy type (compression, teleprompter-optimization, few-shot-compilation).
robos:engine engine 1..* xsd:string Prompt Strategy must declare optimization engine (caveman, dspy, standard).
