This is different though. This is from wikipedia, and aims at structuring data that is used in wikipedia. I am guessing this is because if something changes in the world, then in wikipedia, the information needs to be changed in all articles (all languages, all connex articles etc.). This would add a level of indirection for facts.

Ya but I haven’t seen a new release of DBpedia in years.

Unlike DBpedia, Wikidata is not structured content extracted by parsing Wikipedia articles, but instead a structured collection of factual knowledge created by human editors.

How do you find datasets on wikidata? Their search is hard to use

I made a data import project for Brazilian higher education organizations and was impressed by the amount of documentation, process and tooling available. On the other hand, I was also impressed at how few data imports are completed for me to take as example. To this day I receive dozens of notifications about edits on the entities I created so I’m happy to see it’s alive and well.

you need to use SparQL, on query.wikidata.org there are tons of examples

There is a SPARQL query page, with useful examples included.

In general, Wikidata is not made up of discrete "datasets". Rather, each identifiable real-world entity, event or concept has a unique Q-identifier and a listing of "properties" that apply to that entity. So, to construct a dataset, you'd query for entities that participate in some set of properties you might care about.

Wikidata is a fantastic data source for all sorts of applications, not just for the Wikimedia projects (infoboxes, templates, etc.). I'm also excited about the Wikifunctions project (https://en.wikipedia.org/wiki/Wikifunctions) to created a large body of executable snippets that can be applied to data types.

Wikidata is one of the main data sources in my Conzept encyclopedia project: https://conze.pt (https://twitter.com/conzept__)
