From Meta, a Wikimedia project coordination wiki

Archived notes from Etherpad of the 2020-08-06 meeting.



  • 3-4 of the participants do short (e.g. 5min) presentations on some of their work with modeling GLAM data in Wikibase (or Wikidata), possibly with a focus on mapping existing ontological standards.
  • Q&A after each presentation.
  • Group discussion in the end on lessons learned, challenges, success stories, etc with all participants.
  • Topic and schedule of the next meeting
  • AOB

  • Mohammed's introduction
    • WMDE folks introduce themselves before Lozana takes it away
    • 22 participants
  • Lozana
    • Asks whether participants are comfortable with recording the session
    • Idea of this session was an informal meeting where we could share our experiences with GLAM modelling
    • Lozana is working as a researcher at Rhizome (based in New York) and has been involved in other projects involving Wikibase
    • About Rhizome
      • Working with internet art/net art, which varies from traditional art
      • Art deals with concepts of network, could be a website, performances, videos etc
    • Rhizome needs different metadata standards to describe this kind of art
    • Wikibase instance describing Rhizome artworks
    • How did they deal with describing this kind of art, which is more difficult to describe than traditional art collections?
    • How did people go about mapping nonsingulars?
    • Wikibase offered data-model flexibility unavailable in Wikidata
    • Looked at other standards and one particularly useful standard called PROV
    • Developed their own interpretation of PROV standard which allowed them to describe really complex things
    • Question: how are people thinking about event based modelling in wikidata and wikibase?
      • Rhizome experience so far: both very flexible, but limited when it comes to actually doing event based modelling
    • Event based modelling
      • CIDOC-CRM community does not seem to be as interested in mapping, used a lot by archaeologists
      • presentation slides by Lozana -
      • Possibly also relevant – open access to the paper that goes alongside the presentation:
      • Franziska: really use it as a reference model, how can i relate to the concept of this event or person? Want to use wikibase as a hub for several research projects dealing with different questions about literary history. Fond of event based model, using standards to develop own model
    • If anyone would like to join project page from Rhizome, they would be interested in proposing a new Wikidata property and could potentially do this collectively - a lot of these museums (moma etc) would also likely benefit. Also doesn't necessarily need to be variant of, but something similar - e.g. manifestation of, expression of, instantiation of, etc.
    • The Sphere:
    • Discussion of variant-related issues (among other film modeling issues in Wikidata/Wikibase):


  • Franziska --> do you make use of inverse properties? if yes, how do you deal with that regarding consistency in data recording?
    • Lozana --> We do use inverse properties, variant is best example of this. Consistently use has variant and variant of - we think it would make querying much easier. Another inverse example: creator and creator of
    • Franziska --> so you don't introduce a inverse property for everything, but just for those instances where it is useful
    • Lozana --> try to think about it in terms of what will people query
  • Christine --> Would you run into notability issues for something like an individual casting of a sculpture, in Wikidata?
    • Richard --> I don't think notability would be an issue, at least if it's in a public collection
  • Lozana --> How do we share work progress and learnings across domains? A good converation to have in the future. Also discuss other areas that could be topic of future sessions.

Suggestions for next meeting[edit]

  • I would be interested in looking into setup/configuration of wikibase, because we are struggeling with that. (e.g. setting up a base URI and stuff like that) (Franziska Diehr)
    • As the resident technical writer I'm trying to build out documentation around stuff like this, so please send me concrete questions not answered by at . yay! I'll help however I can, and stuff I don't know I'll look up and publish for everyone's use.
    • oh great, thank you! We will reach out to you! (Also I think maybe we are just kinda lost at the moment ;)
