TwinShip Ontology: Description back to ToC

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. ## Modeling Approach - Restriction-Based Design The 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: - **Precise Semantics**: Restrictions state that instances of a class CAN have certain properties, without forcing classification - **Avoids Unintended Inferences**: Using rdfs:domain would cause any entity using a property to be automatically classified as a member of the domain class - **Flexible Modeling**: Multiple classes can use the same property with different constraints - **OWL Best Practice**: Aligns with OWL 2 design patterns and enables proper use of reasoners ## Visualization and Documentation Most 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. To address this limitation while maintaining correct OWL semantics, we maintain two versions: 1. **Source Version** (in model/ folder): Uses proper OWL restrictions - this is the authoritative version for reasoning and semantic operations 2. **Visualization Version** (auto-generated): A simplified version with explicit rdfs:domain/rdfs:range assertions extracted from restrictions, used solely for documentation generation Both versions are kept synchronized through automated scripts.

Engine Modec back to ToC or Class ToC

IRI: https://twin-ship.eu/twinship#EngineMode

A categorical, ordinal engine operating mode used to classify vessel operation, defined by a power/load range. Individuals are not pre-enumerated or shared globally: the number of modes and their kW ranges are vessel- or engine-specific, derived by a statistical model, so each engine system instantiates its own EngineMode individuals (e.g. a naming convention such as EngineMode1, EngineMode2, ... may be used locally per engine, following the same instantiation pattern as VesselSpeedBin). The engine system declares how many modes it uses via twEngineModeCount; EngineSystem.hasEngineMode lists that engine's full roster of valid modes, while a VoyageLeg's hasEngineMode records which one was active. Ordinal order is derived from twEngineModeLowerBoundInKW, not a separate index. Engine RPM bounds (twEngineModeLowerBoundInRevPerMin, twEngineModeUpperBoundInRevPerMin) are optional and apply where the statistical model bins on engine speed; the bounds are the contract, and any model-internal parameters (e.g. mean and deviation used to derive them) are not stored on the mode. Mode ranges are model-derived and may change when the model is re-fitted: a re-fit should mint new EngineMode individuals so existing VoyageLeg references keep their original meaning.

Engine Speed Binc back to ToC or Class ToC

IRI: https://twin-ship.eu/twinship#EngineSpeedBin

A categorical, ordinal engine speed (RPM) operating region, corresponding to a region of the engine-propeller combinator diagram. Individuals are not pre-enumerated or shared globally: index order increases monotonically with engine/shaft speed, but numeric RPM ranges are vessel- or engine-specific, so each vessel or engine instantiates its own EngineSpeedBin individuals (e.g. a naming convention such as EngineSpeedBin1, EngineSpeedBin2, ... may be used locally, following the same instantiation pattern as EngineMode). For a direct-drive fixed-pitch-propeller vessel, engine speed equals propeller speed directly; for geared or controllable-pitch installations the relationship depends on gearbox ratio and/or pitch setting. Limitation: this class assumes a mechanically-coupled propulsion train (direct-drive or geared) and may not be applicable to diesel-electric or hybrid vessels, where engine (genset) speed is decoupled from propeller speed by the electrical system; how this class should apply to such vessels is not yet resolved and requires domain expert input.
