SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Converts an existing database schema into a formal ontology (TTL/OWL), enabling semantic modeling, knowledge graphs, and reasoner-ready representations.

Core Features & Use Cases

  • Introspects a live database or schema dump to extract tables, columns, keys, and relationships.
  • Generates a structured ontology in Turtle/OWL with Classes, Properties, and Ontological Axioms suitable for reasoning.
  • Use case: transform a PostgreSQL schema into a reusable knowledge graph for data integration and querying.

Quick Start

Connect a database or paste a CREATE TABLE dump and ask the skill to generate a TTL/OWL ontology from the schema.

FAQPage Schema
How do I convert a database schema into an OWL ontology?▼

To convert a database schema into an OWL ontology, you provide connection strings or CREATE TABLE statements, and the tool generates a formal Turtle/OWL semantic model with classes and properties. This transforms relational structures into a reasoner-ready knowledge graph.

Can I generate a knowledge graph from a PostgreSQL or MySQL dump?▼

Yes, you can generate a knowledge graph from a PostgreSQL or MySQL dump by inputting SQL schema dumps or CREATE TABLE statements. The tool extracts tables, columns, and relationships to produce a structured Turtle/OWL ontology output.

What's the best way to create a semantic model from existing SQL tables?▼

The best way to create a semantic model from SQL tables is introspecting a live database or schema dump to extract keys and relationships. It generates a structured Turtle/OWL ontology with ontological axioms suitable for data integration and querying.

Do I need a live database connection to generate a Turtle TTL file?▼

No, you do not need a live database connection to generate a Turtle TTL file. You can simply paste a CREATE TABLE schema dump, and the tool will extract the structural metadata to produce a version-controlled, reasoner-ready ontology.

Does this approach support SQLite and other SQL databases for ontology generation?▼

Yes, this approach supports ontology generation for SQLite and other SQL databases. You can supply connection strings or SQL dumps to produce a formal OWL representation with a configured base URI and scope.

Why convert a relational database schema into a formal ontology?▼

Converting a relational database schema into a formal ontology enables semantic modeling and knowledge graph construction. The resulting Turtle/OWL output provides a reasoner-ready representation with ontological axioms for advanced data integration.
