About

This page assists me in exploring the FactGrid ecosystem and finding my way through it. I am particularly interested in people who have authored scholarly publications but about whom there is little or no information on Wikidata.

Sample entries to work on

People or groups

By knowledge domain

Mathematicians and math students
Natural history organizations

By location

I have been contributing to curating Wikimedia content pertaining to memorial plaques in Jena. While the commemorated people are usually well-described in multiple sources, the story of their respective plaques is usually less accessible, with several incomplete collections and none of them comprehensive or authoritative.

By curation status

Unidentified authors

Open questions

  • Not sure how the "D-" page system works. For instance,
    • Why does Q6591 redirect to D-Q6591 (instead of, say, Item:Q6591)?
    • D-Q6591 hosts data about Q6591, but does this mean that I should create a page D-Q470508 to host data about Q470508 or would that interfere with anything?
    • What is the deeper meaning behind the link for Q6591 being blue (indicating an existant wiki page) and the link for Q470508 being red (indicating a non-existant), when both essentially have their home in the item namespace, i.e. at Item:Q6591 and Item:Q470508, respectively?
    • If I have further information about Item:Q470508 that can not readily be expressed using existing FactGrid properties, should I put these on D-Q470508 or on Item talk:Q470508 or somewhere else?
  • How to enable gadgets?
  • Does anyone here have user scripts?
  • How to see content in a specific set of (or even all) available languages?
  • Are there any templates for communicating SPARQL queries, e.g. as per d:Template:SPARQL2?
  • How to integrate this with WikiCite?
    • How to reuse references from Wikidata here, or vice versa?
    • How to adapt Scholia to work on FactGrid?
The redirect from Q6591 to D-Q6591 is a historical relic. We started with the simple idea to have parallel pages on the same Q-numbers, but it was not a good idea to have pages of the very same name. The direct Q1234-input should lead the the Item, so wie put a D- in front, signalling a "Document-page". The thing is particularly cool on User:Bruno Belhoste's FactGrid viewer: https://database.factgrid.de/viewer/item/Q6641 as the tool is able to amalgamate information. So: direct Q-pages pages are no longer produced. They are left overs from the moves we made in the beginning, and one might just as well delete them.
Use D- only for document transcripts, commentary on documents and translations.
If you have additional information on Item:Q470508 put it on the talk page and Bruno's viewer will also fuse this information into the page it creates.
Why didn't we put our transcripts on the talk pages in the first place? Because that does not bring them automatically into the regular search of the search box top right. That search accesses our D-Pages without further namespace switches. All in all we realised that documents are extremely important on a historical database. At first we felt we should have bigger text properties with full html support and then we went for the Wiki pages and I think the mix is working nicely by now.
Technically we are lagging behind on all your other questions. We are historians trying to understand what we can do with the kid, but we usually need User:Lucas Werkmeister to implement Wikidata features on our server installation. Lucas is on contract with us, so you can ask him if there is a feature you can use on Wikidata which does not work on our site. We need use cases to understand new features and we are happy about anyone who displays a useful thing on the blog for all the others who might profit from it. Lots of things are not as smooth as they are on Wikidata. But our projects come with data they have and they marvel how easy things are compared to solutions they had been working with so far. --Olaf Simons (talk) 08:52, 17 January 2023 (CET)
