Doublet ?

 Question I found this property : powered by (P516). Is there any doublet here? I think we must merge the two property to avoid ambiguity. What do you think? Antoinelam (talk) 12:06, 7 November 2013 (UTC)

Hi! No duplicate because powered by (P516) refers to the machine that provides the propulsion (motor, turbine, rocket, ...), while this property is intended to store the fuel of the propulsion (diesel, benzine, rocket fuel, solar panels, battery, ...). You can add aliases or change the label if you think the label is too ambiguous. --Tobias1984 (talk) 17:47, 7 November 2013 (UTC)

Constraints

Right now only subclasses of form of energy (Q3935690), combustible matter (Q42501), energy source (Q1522115) and energy storage (Q837718) are allowed values. A good outset, but it excludes fuels such as hydrogen (Q556), acetylene (Q133145) and methanol (Q14982). Is there a way to include objects based on subject has role (P2868) and has use (P366) and not just subclass of (P279)? /ℇsquilo 07:31, 5 September 2021 (UTC)
