Other Noteworthy Stuff
- WMDE built two tools to help editors get a better understanding of the
quality of Wikidata's data in a specific area of interest. Try them out and
let us know what you think.
- Item Quality Evaluator
<https://item-quality-evaluator.toolforge.org>
- Constraint Violation Checker
<https://github.com/wmde/wikidata-constraints-violation-checker>
- Collaborative translation of *Cita* is now available
<https://translatewiki.net/wiki/Translating:Cita> on
translatewiki.net.
*Cita* <https://www.wikidata.org/wiki/Wikidata:Zotero/Cita> is a
Wikidata addon that adds citations metadata support to *Zotero*, using cites
work (P2860) <https://www.wikidata.org/wiki/Property:P2860> information
from Wikidata, and enabling users to easily contribute missing data.
*Cita* is currently under development with a WikiCite grant from the
Wikimedia Foundation, and presentation workshops will be held on May 27th
(Spanish) and May 31st (English). More info and pre-registration here
<https://www.wikidata.org/wiki/Wikidata:Zotero/Cita#Presentation_workshop>
.
- RaiseWikibase <https://github.com/UB-Mannheim/RaiseWikibase> is a tool
for speeding up multilingual knowledge graph construction with Wikibase.
Among other features, it can be utilized to create a mini Wikibase instance
with Wikidata properties in a few minutes.
- SPARQL-Blockly <https://langsamu.github.io/sparql-blockly> is a tool
to visualise and construct SPARQL queries as visual blocks (Wikidata
example

visualization via a comment in the SPARQL code (phab:T225883
<https://phabricator.wikimedia.org/T225883>)
- Discussed how to get persistent storage of constraint violations
unstuck as this is a prerequisite to making it easier to analyze and query
constraint violations (phab:T214362
<https://phabricator.wikimedia.org/T214362>)
- Discussed a high-level plan for how to move forward with checking
Wikidata's data against 3rd-party databases
