Wikidata:WikiProject Datasets/Models
This page details how datasets are described on Wikidata.
Model datasets edit
Wikidata requires examples for developing data models. In some WikiProjects the selected examples will be more visible to public examination than others. Here at WikiProject Datasets, the models we choose are very likely to be the subject of discussion among students using datasets and among anyone discussing Wikidata itself. Because of the extra visibility, be mindful when choosing examples to present as models. There are some popular datasets which are encumbered with usage restrictions, a branding story for corporations who have values in conflict with those of the wiki community, or which lack the quality and relevance to merit presenting to large numbers of learners.
Ideally, the datasets which the Wikidata community models here have the following characteristics:
- free and open
- large and diverse enough for use in student exercises including machine learning, while also usable in subsets for smaller projects
- the subject of journalism or academic publication in the humanities which considers the data for social significance
- relevant or meaningful across language and cultural barriers
- has no close tie to any corporate brand
- promotes public benefit
- easy to understand and appreciate even among people who know nothing of datasets
In addition to the datasets themselves here we also need models for dataset creators, tools which use the datasets, and other related concepts. Perhaps not all examples be a perfect example, but please try for the best. Keep Wikidata a community managed project which promotes ethics and values for public benefit.
Proposed model datasets edit
Please edit this section freely and discuss the datasets on the talk page. Perhaps we could seek to identify about 10 datasets to model. The following datasets may meet the above criteria.
- Wikidata?
- OpenStreetMap
- Something from Internet Archive?
- Sloan Digital Sky Survey (Q840332)
- Laser Interferometer Gravitational Wave Observatory (Q255371)
- Protein Data Bank (Q766195)
- something from National Institute of Standards and Technology (Q176691), perhaps from their AI project
- something from the World Bank?
- CKAN
- Human Genome Project
- Global Biodiversity Information Facility (Q1531570)
- The General Index (Q108864972)
- ?? your suggestion
- Unacceptable or not preferred
- Internet Movie Database (Q37312) because only personal use and noncommercial
- CiteSeerX (Q2715061) because of noncommercial license
- AGROVOC (Q292649) this United Nations multilingual agriculture vocabulary has a CC-By license, so incompatible with Wikidata

Dataset creator edit
- organization
- individuals
- ambiguous cases - how to model Wikidata's creators, for example?
Publication featuring a dataset edit
- Intended for modeling academic articles which feature a dataset
- possibly also for books, journalism, or other popular media featuring a dataset
Tool using a dataset edit
- Intended for modeling digital tools which rely on a dataset
- Examples: Wikipedia uses Wikidata; weather and mapping services use public data which government shares
Set profiled in a dataset edit
- intended for either special Wikidata items for the profiled collection, or perhaps just the general concept Wikidata item
- Titanic passengers --> Titanic passengers dataset
Other issues edit
Modeling Wikipedia infoboxes edit
In addition to modeling datasets in Wikidata we eventually need to model datasets for infoboxes across Wikipedias. As of 2021 the French language Wikipedia is still one of the few but growing number to embrace the linking of Wikidata and Wikipedia for infoboxes. Here are a set of examples from French Wikipedia for modeling datasets in infoboxes.
Modeling with intent to import to Wikidata edit
Modeling for FAIR compatibility edit
