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/Table (100% interoperability with search engines, web indexers, and general AI reasoning)
• Specialized Domain Standard: https://cucumber.io/docs/gherkin/reference/#data-tables (de facto standard for domain-specific ALM, BDD, or infrastructure operations)
• Canonical Reference: https://cucumber.io/docs/gherkin/reference/#data-tables
• Agent Guidelines: When autonomous agents generate, expand, or validate instances of robos:DataTable, 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.
