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

Programmatic SHACL Validation

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

const validator = new SHACLValidator();
const result = validator.validateGraph(new OSLCGraphParser({
  "@context": OSLC_CONTEXT,
  "robos:nodes": [
    {
        "@id": "urn:robos:docstring:checkout-payload",
        "@type": [
            "robos:DocString",
            "schema:Text"
        ],
        "robos:step": "urn:robos:step:checkout-payload-docstring",
        "robos:content": "{\n  \"cartId\": \"cart-9821\",\n  \"currency\": \"USD\",\n  \"paymentMethod\": \"credit_card\"\n}",
