The Data Modelling Days 2023 was an online event designed for the Wikidata community and focusing on how we describe and organize data on Wikidata. During 3 days of discussions, workshops and social events, we covered a broad range of modelling challenges and other tricky cases. This event offered a space for editors of all experience levels as well as data reusers to discuss, learn new tips and tools, work on Wikidata's ontologies together and improve documentation and project pages.

This event is now over. You can find the documentation links (slides, videos and notes) in the program below. You can also find the outcomes page where the participants can add what they did during the event. If you have any questions or feedback about the event, feel free to contact Lea Lacroix (WMDE) (lea.lacroix_extwikimedia.de or @Auregann on Telegram).

12:00 UTC 50min	Break - open "live editing" slot
13:00 UTC 50min Notes Video	Scaling Wikidata Query Service - Split the Graph experiment Wikidata Modeling Days - Scaling Wikidata Query Service - Split the Graph experiment Wikidata Query Service is a vital tool for data quality work, especially around modelling data and finding ontology issues in Wikidata. It is currently under a lot of strain and work is ongoing to improve the situation. In this session we want to present the next step towards improving the sytem, the current experiment done by WMF on Splitting the WDQS Graph, followed by a Q&A / Discussion. Speaker: GLederrey (WMF), DCausse (WMF)
14:00 UTC 50min Notes Video	Alternate reference model Slides for Wikidata Data Modelling Days 2023 Friday 14:00 UTC session Wikidata references are separately attached to each statement. This is fine when the source(s) for each statement differ, but this is often not the case, and items can get loaded down with many repetitions of the same reference. There are a variety of gadgets to simplify adding these repeated references. But wouldn't it be better to just state the reference information once, then refer back to it by a short identifier? Wikipedia (most languages) does this now, though we don't necessarily want to follow that model with a separated reference section. Serious problems caused by the current state will be discussed, and options for improving the situation raised with the hope of the session selecting a preferred path forward. Speaker: ArthurPSmith
15:00 UTC 50min Notes Video	Feedback session - How to make it easier to see the bigger picture of the ontology when making very local edits?

Time and links	Sessions and speakers
09:00 UTC 50min Notes Video	Indonesian intangible cultural heritages in Wikidata Wiki Loves Living Heritage at DMD2023 Modelling heritage #1: living and intangible cultural heritage RXerself - Indonesian intangible cultural heritages: Around 11,000 intangible cultural heritages are registered in the official list of the Indonesian Ministry of Education and Culture.1 These range from traditional dances to local speciality dishes, agricultural practices, rituals, and ceremonies. The ample supply of the heritages in the list made it a staple of source to be used in online editing events by the Indonesian Wikidata community. However, the variety of the heritages present may not be smooth when they are inserted into Wikidata as constraints are frequently met. Several examples of these would be presented during the session and we hope to receive more input from the wider Wikidata community in tackling this challenge. Susannaanas - Modelling living heritage. Questions and discussions
10:00 UTC 50min Notes Video	Building a Wikibase.cloud instance for internal knowledge, which exists alongside Wikidata Building and modelling a Wikibase instance from scratch Jason.nlw - Build a Wikibase as a connector between Wikidata and the National Library of Wales's name authority data: challenges, advantages and our experience of building a custom ontology, whist retaining interoperability with Wikidata. Alicia Fagerving (WMSE), André Costa (WMSE) - Wikimedia Sverige is using Wikibase Cloud to build a structured database of the chapter's events, documents and projects (Metabase). We're exploring the strengths and limitations of using structured data for this in comparison with our our own wiki. In the long run, we hope other affiliates would like to join us with their data. In this session, we invite everyone interested in this initiative to discuss some relevant questions, including: How to strike the balance between compatibility with Wikidata and avoiding data duplication? What properties and structures do we need that we do not have on Wikidata? How to best document the work? We have only worked with WMSE's own data so far, so we'll appreciate other perspectives a lot to make sure we're not inadvertently building a platform that only works for our needs. Dr. Gitanjali Yadav - The SemanticClimate.org citizen science initiative values the AR6 reports and wants to make them semantic so they can be re-used faithfully by humans and machines. This includes indexing, linking to Wikipedia/Wikidata, and creating a computable knowledge graph. They have been experimenting with a Wikibase instance on Wikibase Cloud, import a glossary, and point to resources on the Wikimedia projects. Questions and discussions
11:00 UTC 50min Notes Video	Modelling heritage #2: protected areas and monuments Modelling protected areas: a proposal. DMD2023 - Modelling Heritage, Monuments Olea - Modelling protected areas: we'll propose an extrapolated model of heritage designation (P1435) and intangible cultural heritage status (P3259). VIGNERON - Modelling historical monuments. Questions and discussions
12:00 UTC 50min	Break - open "live editing" slot
13:00 UTC 50min Notes Video	Data Modelling Clinic Money, money, money Have you been struggling on modelling a specific type of data on Wikidata? Are you involved in a stalled discussion or a tricky problem? During the Data Modelling Clinic sessions, you can come with a modelling challenge and get input and help from others! Proposed topics: Budgets, grants and other financial information (André Costa (WMSE)) Serialized (web) fiction (Walkuraxx) Facilitators: Lydia Pintscher (WMDE)
14:00 UTC 50min Notes Video	Wikibase federation & WikiCite Slides for Wikidata Data Modelling Days 2023 Saturday 14:00 UTC session Wikicite and some other projects would like to either add much more data to Wikidata, or else to have their own Wikibase that is closely federated. The Wikibase route would mean that many item values (authors, topics, author affiliations, journals, publishers, etc. etc.) should be linked directly to their Wikidata values, rather than duplicated. Can Wikibase be extended to allow external (presumably cached) references for item values? Some ideas for how to do this will be raised, and the discussion should help refine next steps. Speaker: ArthurPSmith
15:00 UTC 50min Notes Video	The QLever SPARQL Engine The QLever SPARQL Engine We will report on the status quo of the QLever SPARQL engine, which is a possible replacement for the current Blazegraph SPARQL engine, as discussed in detail here. We will show, how many queries that are currently very slow or infeasible with Blazegraph, can be processed quickly by QLever. We will also show QLever's context-sensitive autocompletion for constructing SPARQL queries for non-experts. Speakers: Hannah Bast and Johannes Kalmbach
16:00 UTC 50min Notes Video	Wikidata Challenges in the semantic web community Wikidata Challenges in Semantic Web Community This presentation explores the usage of Wikidata across the Semantic Web and Linked Data communities, and the challenges that users face. In the second part of this session, we will collect tips and good practices on data modelling together. According to you, what are the most important things people should keep in mind when organizing data on Wikidata? At the end of the session, we will have a list of ideas, that can be reused later on on presentations or documentation pages. Speaker: AWesterinen
17:00 UTC 50min Notes Video	Modelling gender Modelling Gender on Wikidata We will examine the current process of modeling gender in Wikidata, with a primary focus on the methodologies, prevailing practices, and potential challenges. Our aim is to discuss the decision-making process behind these models, evaluate our existing practices, and address potential concerns. We will explore the various techniques employed for inferring gender information and conduct an in-depth analysis of how such data is documented on Wikidata. This session is designed to analyze the pros and cons of incorporating gender information, offering valuable insights into potential issues. Furthermore, we will engage in collaborative brainstorming to generate suggestions for enhancing future edits within this context. Our overarching objective is to deepen our comprehension of gender modeling in Wikidata and contribute to the ongoing discourse regarding its future direction. Speakers: Jsamwrites (Facilitator), Arielle Rodriguez, Beatrice Melis, Chiara Paolini, Crystal Yragui, Daniele Metilli, Katy Weathington, Marta Fioravanti
18:00 UTC 50min Notes Video	Closing session & next steps Slides Let's have a look at what we discovered and learn during the Data Modelling Days. We will also ask how we can bring these discussions further, and how we can facilitate the conversation between data reusers and people making data modelling decisions. Facilitators: Lea Lacroix (WMDE), Lydia Pintscher (WMDE)

146. Jane023 - participance in the WD:SOAP project, including lists of male & female portraits through the centuries, copies of paintings, WD:Provenance, catalogs of paintings (monographs, collections, and large sales), and lists of paintings indexed in the RKDimages database WD:RKD. I am interested in new ways to model paintings related to other works. Artwork types like engravings or sculpture with multiple editions are challenging.
