Here's what Wikidata says about Earth, an item that is number 2 in the ID list, and also on their front page as an example of incredible data. https://www.wikidata.org/wiki/Q2 https://www.wikidata.org/wiki/Q2 I struggle to find anything interesting on this page. It is apparently a "topic of geography", whatever that means as a statement. It has a WordLift URL. It is an instance of an inner planet. The first perhaps verifiable, solid fact, that Earth has a diameter of "12,742 kilometre", is immediately suspect. There is no clarifying remark, not even a note, that Earth is not any uniform shape and cannot have a single value as its diameter. This is my problem with SPARQL, with "data bases", in that sense. Data alone is useless without a context or a framework in which it can be truly understood. Facts like this can have multiple values depending on exactly what you're measuring, or what you're using the measurement for. And this on the page for Earth, an example that is used on their front page, and has the ID of 2. It is the second item to ever be created in Wikidata, after Q1, "Universe", and yet everything on it is useless.
