Wikibase options

From Wikibase Personal data
Jump to navigation Jump to search


This page attempted to list wikibase options. At some point I switched systems. I am now using PersonalData.IO Wikibase production instance (Q2060). This page still contains information that wasn't passed on though, so it is kept.

Options for configuration

Main services

  • Wikibase
  • WDQS
  • WDQS backend
  • QuickStatements



"The Gadgets extension provides a way for users to pick JavaScript or CSS based "gadgets" that other wiki users provide."


  • EasyQuery.js gadget, needs to be updated for the query endpoint, at the very least. Can be done manually to start.

Customizing the menu

** Special:NewItem|New item
** Special:NewProperty|New property

User rights and namespaces

Constraints handler

  • wikibase constraints work (meaning when you go to an item page, the constraints show up; will need to test myself)

Links on Wikibase installs

Add the following setting to LocalSettings.php:

$wgWBRepoSettings['formatterUrlProperty'] = 'P49';

where formatter URL (P49) depends on the instance (P49 on

  • See here for reference.

Scripting extensions

Embed videos

(redundant with the Widgets extension, possibly)

Query prefixes

  • need to add as default prefix in the query service:
PREFIX pdio: <>
PREFIX pdiot: <>

For reference, this is current list:

PREFIX wd: <>
PREFIX wdt: <>
PREFIX wikibase: <>
PREFIX p: <>
PREFIX ps: <>
PREFIX pq: <>
PREFIX rdfs: <>
PREFIX bd: <>


  • Widgets
  • See for instance Youtube. Error: "Error from line 24 of /var/www/html/extensions/Widgets/WidgetRenderer.php: Class 'Smarty' not found"


  • Is it possible to have multiple namespaces for items?
  • how do we fix autocomplete? (wait until default prefix is set up properly)
  • why do properties on wikidata also have an item associated to them? what is the use case?
  • canonical way to refer from an item to a template? could be used to define ShEx --> Template and create ShapeMap
  • hold properties and their alignment on wikidata/registry
