Hoi,
The WDQ database is likely to include all the information that you need.
It is optimised to be fast. Did you consider to use it?

Can you explain this a bit more? How would I use the WDQ database for this application? (I guess you don't mean via the Web API)

Thanks,

Markus

    Hi,

    Something to be noted here is that initial loading is quite a bit
    slower than it used to be, since there are a lot more classes now.
    We are looking into options of making this faster, but this might
    need a full rewrite to become really fast. The good thing is that
    loading only has to happen once per month (until the next data update).

    There is a known issue with character encoding now, leading to "?"
    in some labels/descriptions. We are looking into it.

    Another new feature is that we now also count properties used on
    property pages:

    http://tools.wmflabs.org/wikidata-exports/miga/#_cat=Properties/Uses%20in%20properties=1%20-%2020000

    Compared to the old data, we have a lot more objects in some classes
    now (it's amazing how many asteroids, first names, bands, and legal
    cases there are ...). It seems we have more than 10,000 galaxies on
    Wikidata already.

    Here are our top-100 classes by number of instances:

    http://tools.wmflabs.org/wikidata-exports/miga/#_cat=Classes/Number%20of%20direct%20instances=10000%20-%2010000000

    Other classes have a lot of subclasses rather than instances:

    http://tools.wmflabs.org/wikidata-exports/miga/#_cat=Classes/Number%20of%20direct%20subclasses=1000%20-%20200000

    And of course, as usual, you can browse individual properties to see
    the classes of objects they are used on ("What kind of things have a
    diameter?") and browse classes to see which properties are typical
    for them ("What kind of statements do we have about poems?").

    Cheers,

    Markus

        Hi all,

        there  are some good news: I updated the Miga Classes and Properties
        Browser which collects several statistics about classes and
        properties
        used in Wikidata. In the future it will be updated monthly.

        You can find it here:
        http://tools.wmflabs.org/wikidata-exports/miga/

        Hint: Since Miga uses WebSQL, the browser does not run in Internet
        Explorer or Mozilla Firefox.

        Best regards,
        Markus
