To the question from Vishnu Mohan: I would like to know what will happen to chembox and drugbox? I think this is a wrong question: wikidata don't store complete chemboxes or drugboxes, but only each parameter, that will be used in this boxes (like "smelting point" etc.). So each Wikipedia will have or can have different boxes - but for a given substance all Wikipedias will show the same smelting point. dr.cueppers (redaction for chemistry in German-WP) Dr. Cüppers GmbH Hübnerstraße 2 33104 Paderborn 05254 935700
