The immidiate use of Wikidata is not obvious, apart from interwikilinks. However, it is clear that proper semantic linking is key to enable innovation, and just by looking at examples like Reasonator, Histropedia and Wikidata Query, the power of it is revealed. So be careful to always connect new articles and also do take the time to add some statements to make it possible to enable experiments.
We do need to find out if there are any ESD related properties that needs to be added to Wikidata. Are there any databases or authorities whose IDs are relevant to add to entities on Wikidata?
