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

Data Store robos:DataStore

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

dcterms:title robos:engine robos:evidence

RobOS classification: Data stores & messaging. These RobOS-owned codes use Schema.org CategoryCode vocabulary.

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