About [[EOL:Website-activerecord.attributes.eol statistic.total triples/en]]
As with all "activerecord.attributes.*" translations, these are translations used for creating forms and generating error messages and the string provided is meant to capture a particular field on a particular model.
However, in this case I suppose it's worth clarifying that a "triple" is a form of data storage, where you have a predicate, relationship, and object. So, for example, a single triple might be "American robins [predicate] prey on [relationship] worms [object]". In this case, we're talking about an "eol statistic", so we're counting the total number of triples in the database at a given point in time.
I've added that to the qqq.
