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/DataStore (100% interoperability with search engines, web indexers, and general AI reasoning)
  • Specialized Domain Standard: https://www.iso.org/standard/63555.html (de facto standard for domain-specific ALM, BDD, or infrastructure operations)
  • Canonical Reference: https://schema.org/DataStore
  • Agent Guidelines: When autonomous agents generate, expand, or validate instances of robos:Database, 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

Database robos:Database

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

Property Constraints & SHACL Rules

Property Path Name Multiplicity Data Type Constraint Rule / Validation Message
dcterms:title Title / Display Name 1..* xsd:string Database must have a title or display name.
robos:engine engine 1..* xsd:string Database must declare its engine (postgresql, mysql, sqlite, oracle, etc.).
robos:databaseName databaseName 1..* xsd:string Database must specify a logical database name.
robos:host Routing Hostname 1..* xsd:string Database must specify a host address or service DNS.
