This is a wholly-owned LLC that provides opt-in services for third-party content reuse, delivered via API services.

A Wikidata query service JNL file for public use

Back in 2019 I wrote a blog post called Your own Wikidata Query Service, with no limits which documented loading a Wikidata TTL dump into your own Blazegraph instance running within Google cloud, a near 2 week process.

A first look at WikiCrowd

I have quite enjoyed the odd contribution to an app by Google called Crowdsource. You can find it either on the web, or also as an app. Crowdsource allows people to throw data at Google in controlled ways to add to the massive pile of data that Google uses to improve its services and at…
