Best way to add WorldCat items?[edit]

The Portland Bee (Q55833876) existed from 1876 to ~1880. There were both daily and weekly editions; and there were two owners. (Founder sold to second owner; second owner sold it back to the founder.) These facts, I think, account for the fact that OCLC/WorldCat has three entries:

Should I add all three to Q55833876? Or is there a better way to handle this? -Pete F (talk) 22:33, 30 July 2018 (UTC)

Seems like a common issue with newspapers. The Sellwood Bee has the same problem -- it's been a continuous paper since 1906, but has used the names "Sellwood Bee," "Sellwood-Moreland Bee," "The Bee," and briefly "The Milwaukee Bee". OCLC seems to have a different identifier for each (or at least for some of them. Wikidata wants to only have one OCLC identifier per item; to me, it seems silly to create a separate data item here for each, simply because WorldCat/OCLC chose to do so. But maybe I'm wrong. What's the best practice? If we did make several different data items, how do we go about linking them to Wikipedia? -Pete F (talk) 23:47, 30 July 2018 (UTC)
One can easily add several identifiers per item. The "named as"-qualifier can be used to indicate how they differ.
I leave it to the more active project participants to decide what you consider the best way to handle this. Personally, I wouldn't create a new item on each change of ownership (sample Q7743126#P127 just gives a start date). I think it's debatable if each new name should get a separate item.

Thanks @Jura1:, it sounds like you and I have the same instincts, and I like the idea of pairing it with "named as." I agree it would be good to hear from more people. In early discussions about Wikidata (~2013) I recall hearing from a couple people that there was no such thing as a fact too insignificant for Wikidata. So, for instance, every grain of sand might have its own Wikidata entry. That seems several steps beyond what's practical or useful to me, but I don't know how much it is part of the defining spirit of Wikidata. Under that theory, of course we would have separate entries for each name a publication had...but then, it becomes challenging to link the overall publication (the thing that carries the significance and the identity in "human-scale" terms) to other Wikimedia projects etc. When I add a second OCLC number, I get this warning: "single value constraint - This property should only have a single value with the same distribution qualifier." I wonder if that is merely a cautionary note, or if it means that some day somebody will come along and change it to comply with a policy. Difficult to tell, and I'd like to understand better. Perhaps Property talk:P243 would be a better place for me to ask. I see a similar question there from June 2018, but no answer yet. -Pete F (talk) 17:04, 1 August 2018 (UTC)

Title language of journals[edit]

Minor thing: I just noticed that these are English by default (sample fix).

Mismatch in taxonomy of Wikidata and English Wikipedia[edit]

This is a vexing issue in my work on newspaper articles, though it would apply to other subject areas as well:

There is not (and should not be) a perfect 1:1 relationship between Wikidata items and Wikipedia articles. Case in point:

w:en:German language newspapers of Oregon discusses several newspapers.

Wikidata should have items for each of those newspapers. (Currently, here are two: Q55627861 and Q57207037.)

It seems to me that these items and the Wikipedia article should be linked, but it's not possible to do so. I tried to link each of the Wikidata items to the Wikipedia redirect page for each newspaper, but Wikidata "resolves" the redirect to the article it points to, so it's not possible to add a Wikipedia link to the second (or third, etc.) Wikidata item related to that article.

What's the best approach here? -Pete F (talk) 19:45, 10 October 2018 (UTC)

A possible, if incomplete, approach: I could create a Wikidata item for "German language newspapers of Oregon," and make each newspaper item an "instance of" it. I suppose that's probably the only viable way to do it that fits into the way Wikidata works...yes? -Pete F (talk) 19:49, 10 October 2018 (UTC)
  • The article you mention seems more like a list. I added a sparql equivalent to the item that could be used to generate the list (provided that the items have place of publication and language). You could try to add an automated w:Template:Wikidata list at Wikipedia. --- Jura 21:24, 10 October 2018 (UTC)
