Ship launch date?Edit

Any reason why this can't be used for ships? It is after all where the phrase originates. Danrok (talk) 21:44, 23 June 2013 (UTC)

  • It is hard to make common name for these events types in Russian. It must be named "дата спуска на воду" for ships but "дата запуска" for launch vehicles. — Ivan A. Krestinin (talk) 06:21, 24 June 2013 (UTC)
    • However, I think it is still essentially the same. Shouldn't we try to generalize properties? I don't speak Russian, but how about something like "дата спуска на воду и́ли запуска"? Petr Matas 06:01, 19 November 2014 (UTC)
      • Double naming says that we mix different entities in one object. This is not good from point view of data structure. Why you suggest mix rocket lift off time and ship launch? Why not date of birth (P569) and ship launch? Another point: rocket launch time in known with high precession (usually seconds, sometimes milliseconds). For ships only year is known often. Space vehicles and ships are described in different sources / databases, different groups of users are interested in these areas. I see only one point for this merge: these two different concepts are described using single word in English language. — Ivan A. Krestinin (talk) 18:46, 19 November 2014 (UTC)
        • You are probably right. I came to this idea when thinking about the fictional star ship Enterprise, where the analogy is stronger. Still, I think that the similarity between different properties should be recorded somehow. If properties could have properties, I would say that time of spacecraft launch (P619) and ship launch date are both a subclass of the date of first use or something like that.

Future launchEdit

Why is there a constraint on the value of this property forcing it to be a date in the past? Shouldn't it also be used for planned launch dates? Regards, -- Whidou (talk) 11:55, 30 March 2018 (UTC)
