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

Comment robos:Comment

Governed by W3C SHACL shape urn:robos:shape:CommentShape within the Organization & Teams (robos.org) (robos.org) package store.

robos:content robos:author robos:createdAt robos:parentItem

RobOS classification: Projects & work items. These RobOS-owned codes use Schema.org CategoryCode vocabulary.

Property Constraints & SHACL Rules

Property Path Name Multiplicity Data Type Classification Constraint Rule / Validation Message
robos:content content 1..* xsd:string Testing & behavior Comment must have content.

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,

    {
        "@id": "urn:robos:organization:comment-sample",
        "@type": [
