Notes[edit]

  • Overview for new attendees: this is a monthly call about WB development and bringing like-minded folks together to expand on how to use WB
  • Last month's preso from Lozana (see notes)
  • Today: open discussion on success stories, etc.
  • Introductions (see participants list :) )
  • Lozana discussed PROV last time, we wanted a further discussion this time on different ontologies
  • Talks about us having an open sessoin where different people can share their experience using standard ontologies in custome Wikibases or even in Wikidata
  • CIDOC represents a common, event-based standard. Difficulties in implementing such standards in WB
  • CIDOC specialists hoped for but not currently present
  • Lozana solicits questions on the event-based topic
  • https://seco.cs.aalto.fi/publications/2019/hyvonen-en-sampos-2019.pdf  - group of knowledge websites on various topics  which are using CIDOC-CRM model in the background e.g. https://biografiasampo.fi/  collection interlinked biographies of prominent people in Finland.
  • Rhizome: custom ontology -- project page (link) shows how to map onto PROV standard
  • Lozana explains the reasom why we Rhizome focuses on CDOC is not because of special preference but because it is a commons standard and it is also event based.
  • Prov is a standard for digital provenance. where it is a relevant to cidoc crms,
  • Lozana presents an overview of PROV & Rhizome's implementation
  • https://www.wikidata.org/wiki/Wikidata:Federation_input
  • https://artbase.rhizome.org/wiki/Property:P117
  • https://www.wikidata.org/wiki/Wikidata:WikiProject_Digital_and_Performative_Arts/Provenancial_Data
  • Feel free to go and have a look and add comments here or on Telegram
  • We have our own custom ontology because it's useful to be able to connect accross instances
  • where relevant, things have been mapped to prov standards
  • Types of records have been separated; artworks and their differnt variatins altjought its not a fully fledged standard
  • Basically as a group we were interesting to see if there was a better way not necessarily similar to what we have done at Rhizome
  • Lozana: one of hte way I've been trying to go about with documentation is to write Wikiproject pages for the differnt project I'm involved in
  • Question: how do you do trhe mapping in the wikibase --> yes we use the exact map [missed point] which is also done in wikidata.
  • For now each of the properties we are able to connect it to the wiki. if people really want to learn, they could follow the proper ontology
  • "Proper federation" --> Wikidata folks.
  • Active project: federated properties, as in properties from Wikidata that can be used on your Wikibase instance.
  • On the roadmap: other federation-adjacent topics (reusing items, etc.) -- "far future, not this year"
  • Discussion about what need to happen with federation on the wikipages can be communicated with the people whon were invioved in it. https://www.wikidata.org/wiki/Wikidata:Federation_input
  • Rhizome would be interested to do some more work with WMDE with regrds to federatrion
  • Question: If you want to use a certain published model in your wikibase, such as CIDOC-CRM, would you 1) upload the model properties "as is" into your wikibase? (Lozana: No -- not practical) Or 2) would you do a selection of properties and then upload, or 3) would you enter them one by one?
  • With zero human curation and everything done with scripts, maybe it's possible. But creating "third-tier" entities programmatically doesn't seem like a good idea.
  • Lozana --> openrefine could be the solution to [missed part] move items around different databses (in connection with federation)
  • There is also some news on making OpenRefine work with Wikibase. ; adding labels , statements, overriding, etc to Wikibase -- OPenRefine can now read your manifest and understand your custom data structure, not just Wikidata's any more
  • It will be GUI based
  • Question --> Wikibaseimport extension does allow importing properties attached to items, but it does not import all properties(?) -- see below
  • Discussion on modeling events and RDF
  • For the example with our case at Rhizome we care about finding out in one query all the artworks that were made by an event like web archiving
  • Using WikibaseImport / WikidataIntegrator to successfully import properties/items
  • In WikibaseImport, use --all-properties to load all properties with an item (found onhttps://stuff.coffeecode.net/2018/wikibase-workshop-swib18.html#_via_wikibaseimport_code_importentities_php_code)
  • This blog post https://medium.com/@thisismattmiller/wikibase-for-research-infrastructure-part-1-d3f640dfad34 demonstrates how to use add_properties.py and add_items.py available in this repohttps://github.com/SemanticLab/data-2-wikibase
  • Question? --> Are there better ways to document our work going forward, on different platforms; work with data models or also data upload and import and exchange.
  • Sarah, we'd like to have documentaiton on the within the wiibase instance
  • Dan -- hoping to have a clear space to find stuff  https://wikibase-registry.wmflabs.org/wiki/Main_Page
  • Exhortation to add your WB instance to the registry above; plan to add all docs tohttps://mediawiki.org/wiki/Wikibase
  • Provenance presentation that was shared by Lozana --https://docs.google.com/presentation/d/1aAotYvqgUYevqttYjJytRBQL5t9hx7tz2rq_nAH1KXI/edit?usp=sharing
