During my first week at Newspeak house while explaining Wikidata and Wikibase to some folks on the terrace the topic of Dams came up while discussing an old project that someone had worked on. Back in the day collecting information about Dams would have been quite an effort, compiling a bunch of different data from different sources to try to get a complete worldwide view on the topic. Perhaps it is easier with Wikidata now?
Below is a very brief walkthrough of topic discovery and exploration using various Wikidata features and the SPARQL query service.
A typical known Dam
In order to get an idea of the data space for the topic within Wikidata I start with a Dam that I know about already, the Three Gorges Dam (Q12514). Using this example I can see how Dams are typically described.
