Properties to use

Ship types

Most ships must be instance of (P31) one or multiple ship types.

Ship types represent a variety of grouping, that may be functional, structural, historical... They may be very generic or very specific. Some examples:

• ferry (Q25653), guided missile destroyer (Q2607934), ore-bulk-oil carrier (Q15272), research vessel (Q391022), museum ship (Q575727)...

See the current list of ship types.

Mandatory ship type properties

Ship types are items, defined by:

• instance of (P31) ship type (Q2235308), and
• subclass of (P279) ship (Q11446) or any other ship type.

Recommended ship type properties

Other properties relevant to ship types:

• ship types are primarily defined by the other types that they derive from (via subclass of (P279)).

Ship classes

Many larger ships are more or less arbitrarily assigned to classes [ ship class (Q559026) ] that share design, builder or manufacturing characteristics.

Ships are associated to ship classes using property vessel class (P289), leaving instance of (P31) to indicate ship type.

See the current list of ship classes and submarine classes.

One example:

• Kotlin-class destroyer (Q206562) instance of (P31) ship class (Q559026) and subclass of (P279) guided missile destroyer (Q2607934).

Essential ship class properties

• instance of (P31) ship class (Q559026), and
• subclass of (P279) one specific ship type (Q2235308), or one specific ship class (Q559026), rarely more than one parent entity.

Mandatory ship class properties

• short name (P1813)
• operator (P137)
• named after (P138) one of its ships, normally the lead ship (Q2095057), which is itself named after some other item
• image (P18)
• service entry (P729)

Recommended ship class properties

• manufacturer (P176)
• country of origin (P495)
• armament (P520)
• NATO reporting name (P561)
• follows (P155)
• followed by (P156)
• service retirement (P730)

See the latest list of all ships types, ship classes, submarine classes.

Individual ships

Example:

• Titanic (Q25173) instance of (P31) four funnel liner (Q3362987), vessel class (P289) Olympic-class ocean liner (Q767166), owned by (P127) White Star Line (Q320466), port of registry (P532) Liverpool (Q24826)...

Essential ship properties

• instance of (P31) one of the ship types
• vessel class (P289) one of the ship classes (only needed if the ship is of a specific class)

Mandatory ship properties

• image (P18)
• short name (P1813)

Recommended ship properties

• operator (P137)
• manufacturer (P176) the shipbuilder.
• yard number (P617)
• service entry (P729)
• country of registry (P8047)
• port of registry (P532)
• shipping port (P504)
• named after (P138)
• gross tonnage (P1093)
• length (P2043) only for the overall length.
• beam (P2261) width at the waterline.
• width (P2049) overall width (widest point).
• draft (P2262) vertical distance between the waterline and the bottom of the hull.
• location of creation (P1071)
• armament (P520)
• powered by (P516)
• significant event (P793) for events. See the list of possible significant events below for possible values and qualifiers.
• IMO ship number (P458)
• MMSI (P587) Maritime Mobile Service Identity.
• call sign (P2317) of radio station (these are the 3 most commonly used ship identifiers)
• cause of destruction (P770) if the ship was destroyed, then this property can be used to indicate what caused the destruction, along with point in time (P585) as a qualifier.
• conflict (P607) to specify any wars or battles in which the ship participated. Including merchant vessels, troop transports, etc.
• pennant number (P879) classification number sometimes painted on the hull
• Terms: Ship

Ship name prefixes

Many ships should be somehow related to one of another ship prefix (Q1501958).

The property to use for establishing that link still has to be identified.
