English: Wikidata is not just some kind of database application. Consequently, a logo for Wikidata should not focus on the pure technical aspect. It is the democratic purpose of Wikidata that has to be expressed by the logo - Wikidata's data is for everyone. This logo proposal symbolizes that very granular level of Wikidata - regarding both aspects that are actually meaningful from a user perspective: Gathering and distribution of data. Small chunks symbolizing chunks of data are joining together to form a harmonic superset: Wikidata. The growing circles symbolize the data distribution - Wikidata will send out its data without applying any privileges - everyone may use the data.
For the purpose of using all WMF colours, in one version of the logo a red dot has been placed in the logo's centre. However, from an aesthetic point of view, the one without the dot should be preferred since the red dot puts more focus on technical centralism than on the democratic intention. The monochromatic version even more inherits the variety of data that is gathered.
