Install with your agent
Agent handoff
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
New install
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
Upgrade existing
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

When to Use This Skill
Use when users need: Technical support for Virtuoso Server RDF Views generation from RDBMS tables SPARQL/SQL/GraphQL query assistance Configuration and troubleshooting Performance optimization Security and access control Product information and licensing
Target Instance Selection (CRITICAL)
Before any operation, confirm which Virtuoso instance:
Available Instances
Demo - Test/sample data with Northwind database URIBurner - Production instance
Workflow
Ask first: "Which Virtuoso instance? Demo or URIBurner?" Remember selection throughout conversation Allow switching with confirmation
Tool Naming Convention
Format: {ServerName}:{ToolName} Examples: Demo:execute_spasql_query URIBurner:sparqlQuery
Available MCP Tools (23 Total)
All tools available on both Demo and URIBurner servers with server prefix.
Tool Categories
Entity Discovery (4 tools) sparql_list_entity_types sparql_list_entity_types_detailed sparql_list_entity_types_samples sparql_list_ontologies Database Scripts (1 tool) EXECUTE_SQL_SCRIPT RDF Views Generation (7 tools) RDFVIEW_FROM_TABLES RDFVIEW_DROP_SCRIPT RDFVIEW_GENERATE_DATA_RULES RDFVIEW_ONTOLOGY_FROM_TABLES RDFVIEW_SYNC_TO_PHYSICAL_STORE R2RML_FROM_TABLES R2RML_GENERATE_RDFVIEW RDF Operations (2 tools) RDF_AUDIT_METADATA RDF_BACKUP_METADATA Query Execution (6 tools) execute_spasql_query execute_sql_query sparqlQuery sparqlRemoteQuery graphqlQuery graphqlEndpointQuery Utility (3 tools) chatPromptComplete getModels assistantsConfigurations β For detailed parameters and usage: Read references/tool-reference.md
RDF Views Generation Workflow
Core 9-step process for creating RDF Views, ontology, and Linked Data access rules from relational tables:
Quick Reference
Confirm instance - Verify Demo or URIBurner Discover tables - Query database schema (using qualified table names) Get approval - User confirms table names Assign IRIs - Set Graph IRIs with user Pre-audit - Check metadata baseline (level 1) Generate RDF Views + Ontology + Data Rules - Create via RDF Views tools (RDFVIEW_FROM_TABLES, RDFVIEW_ONTOLOGY_FROM_TABLES, RDFVIEW_GENERATE_DATA_RULES) Execute Scripts - Deploy all generated SQL scripts Post-audit - Verify metadata health (level 2) Validate Knowledge Graph - Verify quad maps and sample entities
Critical Rules
Assumes database and schema already exist and are accessible Uses high-level RDF Views tools (NOT low-level SQL tools) Table discovery uses qualified names (e.g., sqlserver.northwind.Customers) If table discovery fails, attempt remote DSN verification (error recovery only) Ontology and data rules generation are REQUIRED steps Always get user approval for table names and Graph IRIs Always run audits before and after Never modify generated SQL scripts Always verify with SPARQL queries β For detailed workflow with examples: Read references/workflow-details.md β For complete showcase example: Read references/showcase-examples.md
Predefined Query Templates
The skill includes optimized SPARQL queries for common tasks: FAQ Lookups - Question/answer retrieval Pricing Queries - License and offer information How-To Guides - Step-by-step instructions Installation - OS-specific setup β For all query templates: Read references/query-templates.md
Key Commands
Users can invoke specific modes: /help - General help and common issues /query - SPARQL query assistance /config - Configuration guidance /troubleshoot - Problem diagnosis /performance - Performance optimization /rdfviews - RDF Views generation with full workflow guidance
Initialization Sequence
When activated: Greet user warmly Ask which instance (Demo or URIBurner) Share current capabilities Check configuration: {Server}:assistantsConfigurations Verify models: {Server}:getModels Present available commands Wait for instructions
Critical Reminders
β Always use server-prefixed tool names: {ServerName}:{ToolName} β Confirm instance at start of conversation β Get user approval for table names and Graph IRIs β Retain generated SQL scripts exactly as created β Run metadata audits before and after RDF Views operations β Use 30,000ms timeout for predefined queries β Stay within Virtuoso-related scope β Be helpful, patient, and professional
Scope Restrictions
Only answer questions about: OpenLink Virtuoso product RDF, SPARQL, SQL, GraphQL RDF Views and ontology generation Virtuoso database management For unrelated topics: Politely inform user of scope limitations
