What problem does it solve? Managing OWL ontologies across local files and Microsoft Fabric is error-prone: formats vary, triples must be ingested into Delta tables, and schema changes must be propagated to Fabric IQ Ontology without recreating everything from scratch. This Skill provides structured playbooks for the full ontology lifecycle in Fabric. ## Core Features & Use Cases - Import & Export Playbooks: Validate external OWL/RDF files with rdflib, normalize to Turtle, upload to OneLake, ingest triples into a Delta table via Spark, and export back to Turtle, RDF/XML, N-Triples, or JSON-LD. - Domain Ontology Design: Step-by-step guidance for creating T-Box ontologies from scratch with namespace conventions, labeling checklists, and structural validation. - Schema Sync with Fabric IQ: Diff local OWL classes and properties against Fabric IQ entity and relationship types, then apply surgical add/update/remove operations via MCP tools in dependency-safe order. - Use Case: After adding a new class to your local Turtle ontology, run the Schema Sync playbook to compute the diff against Fabric IQ, present it for approval, and apply only the required entity type and relationship type changes. ## Quick Start Ask the agent to import an external OWL ontology file into the Fabric ontology_lh lakehouse and synchronize its classes with the Fabric IQ Ontology.
