Wikidata showing chemical properties with references

As you have seen in my blog, I'm a fan of Wikidata. Because of the Open nature, it's creating an enormous eco-system, in which many scientists are involved and with innovative visualizations. Data comes from many trusted databases, but the complexity of it all requires some hard decisions now and then. However, unlike many other databases, Wikidata has data provenance high on the agenda: all statements can be complemented with primary literature references, which I have been using when porting the pKa data.

A new visualization of the data is provided by SQID Markus Kr√∂tzsch et al. And this interface propagates the references for each bit of fact, though by default hidden behind an arrow icon at the top right of the fact. Clicking that will show the provenance, though that is currently still often a database, rather than primary literature.

and a hazardous chemical exposure.
I really like where this is going! Why have publishers not been able to do something like this in the past 20 years?? This is knowledge dissemination as we want to see it.
