description	Create or update a custom DAV DET variant based on RDF Import DET for Virtuoso. Use when the task is to scaffold, modify, or document a DET that ingests RDF documents into the Quad Store, supports one or more Virtuoso-supported RDF document types, implements the required _DAV_* hook family, or needs verification SQL, WebDAV probes, and VAD/source integration notes.

RDF DET Variant Generator

Use this skill when building a custom DAV DET derived from the RDFImport pattern for RDF-bearing document types supported by Virtuoso.

What This Skill Produces

• DET SQL scaffolding derived from RDFImport
• Hook coverage checklist for required DB.DBA.<DetName>_DAV_* functions
• Variants for multiple RDF document types
• Verification SQL and WebDAV probes
• Packaging guidance for:
  • {HOME}/Documents/Management/Development/virtuoso-engine/binsrc/yacutia/sql/
  • {HOME}/Documents/Management/Development/ods-virtuoso/briefcase/sql/

Trigger Conditions

Use this skill when the user asks to:

• create a DET similar to RDF Import
• support additional RDF document types
• generate a new Quad Store ingestion DET
• scaffold a DAV DET that loads RDF into named graphs
• create or update DET SQL hooks and validation queries

Workflow

⛔ PRE-BUILD CHECK: Before producing output, re-read the relevant workflow section above and re-read any checklists or verification gates defined in this skill. Confirm each checklist item before writing output. Build to pass — do not retro-fit. Apply the CLAUDE.md Anti-Drift Protocol: re-read spec section before build, gate-first validation, section-by-section delivery.

1. Identify the DET name, target folders, and desired graph behavior.
2. Confirm the RDF document types to support.
3. Load the implementation checklist in references/det-hook-checklist.md.
4. Load the RDF-type guidance in references/virtuoso-rdf-doc-types.md.
5. Use references/rdf-det-template.md to generate or update the DET.
6. Generate validation queries from references/verification-queries.md.
7. Provide VAD/source integration notes and release/build reminders.

Output Requirements

• Keep runtime SQL in Virtuoso procedure form.
• Keep verification artifacts separate from runtime code.
• When generating listing logic, prefer explicit vector accumulation unless there is a proven reason to use builder helpers.
• Ensure the DET returns a proper array of DAV row vectors from _DAV_DIR_LIST.
