Properties to use edit
Ship types edit
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 edit
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 edit
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 edit
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 edit
- 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 edit
- 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 edit
- 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 edit
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 edit

- 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

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.
