RDF Ontologies Skill

What is RDF?

Resource Description Framework: Semantic web standard for expressing knowledge as triples

CopySubject → Predicate → Object
Alice → hasEmail → alice@example.com
Feature-001 → hasTitle → "Test Audit"

Turtle (TTL) Syntax

Copy@prefix spec: <http://ggen.io/spec/> .

spec:feature-001 a spec:Feature ;
    spec:title "Feature Title" ;
    spec:priority spec:P1 ;
    spec:hasUserStory spec:us-001 .

spec:us-001 a spec:UserStory ;
    spec:title "As a user..." ;
    spec:hasAcceptanceCriterion spec:ac-001 .

Workflow

1. Create .specify/specs/NNN-feature/*.ttl
2. Validate: cargo make speckit-validate
3. Render markdown: cargo make speckit-render
4. TTL is source of truth (never edit .md)
