Ongoing: Wikidata Cleanup 2024 - Romaine continues his initiative, "Wikidata Cleanup," to coordinate community efforts in addressing the problem of items missing basic properties during the last ten days of 2024, when many users have extra time due to holidays. The aim is to improve data quality by focusing on ensuring all items have essential properties like "instance of" (P31) or "subclass of" (P279), adding relevant country and location data, and maintaining consistency within item series.
Upcoming events: Data Reuse Days - online event focusing on projects using Wikidata's data, 18-27 February 2025. You can submit a proposal for the program on the talk page until January 12th.

Papers
Library Data in Wikimedia Projects: Case Study from the Czech Republic by Jansová, L., Maixnerová, L., & Š´tastná, P. (2024). "The paper outlines the collaboration between the National Library of the Czech Republic and Wikimedia since 2006, focusing on linking authority records with Wikipedia articles and training librarians and users. By 2023, the National Library provided most of its databases under a CC0 license, launched a "Wikimedians in Residence" program, and collaborated on projects involving linked data and using authority records in Wikidata. This partnership has enhanced their cooperation for mutual benefit, identifying key factors for their successful long-term collaboration."

We (Peter F. Patel-Schneider and Egezort) want to run a course on the Wikidata Ontology for a limited number of participants. Designed for those already familiar with Wikidata, it will present information about ontologies and how they form the core of Wikidata, incorporating several exercises on analyses of and fixes to the Wikidata ontology. Upon successful completion (ending with a group project in consultation by us), participants will receive certificates. Please give feedback and suggestions to improve the structure and course content (found in more detail at WikiProject:Ontology Course) which will be incorporated into our Wikimedia rapid grant application to support the effort. Interested in helping or want to share your thoughts? Let us know.
Several database changes will impact Wikidata in the coming months, including the migration of the term store (wbt_ tables) to a dedicated cluster to improve performance and enable future growth. This move will speed up most Wikidata SQL queries but prevent direct joins between term store data and other Wikidata tables. Additionally, the wb_type table will be removed, with its mapping hardcoded in Wikibase, simplifying the codebase. More details.
