* [39:41] Explanation of Wikibase Technology: SQL datastore of triples. There is a CRUD API that interfaces with that. But it also uses a graph database to enable SPARQL queries. The SQL database gets fed into BlazeGraph using the 'updater' but this has a delay (a second to several hours). So query results may not be as up to date as what is in the database.

* [46:29] Namespaces
** [48:55] Can you move pages between Namespaces? Yes. (show how)
** [49:25] Do users have their own sandbox namespace? Yes everything under your username is a namespace e.g. you can just make [[User:Alexbfree/ExampleSandboxPage]]. (This could be useful for testing things privately before they are shared with other users)
** [50:46] The Easy Query Gadget [[MediaWiki:Gadget-EasyQuery.js]] which shows all items that have this property. Activated by default for everyone. Just click the [...] next to a title.
