. . "Complete TwinShip ontology for digital twins of ships. This is an aggregate ontology that imports the base foundation (twinship-base) plus all domain modules. Use this ontology to get the complete TwinShip conceptual model including vessels and weather. For modular development, import twinship-base and specific modules instead.\n\n## Modeling Approach - Restriction-Based Design\n\nThe TwinShip ontology follows a restriction-based modeling approach using OWL class restrictions (owl:Restriction with owl:someValuesFrom, etc.) rather than simple rdfs:domain and rdfs:range assertions. This is the recommended OWL engineering practice as it provides:\n\n- **Precise Semantics**: Restrictions state that instances of a class CAN have certain properties, without forcing classification\n- **Avoids Unintended Inferences**: Using rdfs:domain would cause any entity using a property to be automatically classified as a member of the domain class\n- **Flexible Modeling**: Multiple classes can use the same property with different constraints\n- **OWL Best Practice**: Aligns with OWL 2 design patterns and enables proper use of reasoners\n\n## Visualization and Documentation\n\nMost ontology visualization and documentation tools (WIDOCO, WebVOWL) were designed for RDFS-style ontologies and provide limited support for OWL restriction patterns. They expect simple rdfs:domain and rdfs:range assertions to generate diagrams.\n\nTo address this limitation while maintaining correct OWL semantics, we maintain two versions:\n\n1. **Source Version** (in model/ folder): Uses proper OWL restrictions - this is the authoritative version for reasoning and semantic operations\n2. **Visualization Version** (auto-generated): A simplified version with explicit rdfs:domain/rdfs:range assertions extracted from restrictions, used solely for documentation generation\n\nBoth versions are kept synchronized through automated scripts."@en .
