Hello,
Our organization currently uses Wikidata subject terms for our taxonomy, but we apply them manually. We are researching setting up a Wikibase, but I am curious about the interoperability with Wikidata.
Does anyone have any examples of a Wikibase instance that is interoperable with Wikidata?
Thank you,

(MHz Curationist logo) MHz Curationist is a project of the MHz Foundation http://www.mhzfoundation.org.
I operate a Wikibase of domain names: https://domains.wikibase.cloud/wiki/Project:Home.
If Wikidata is organized around concepts, this Wikibase is organized around domain names which are then linked back to their Wikidata ID. For example, you can see that the item for "cnn.com" https://domains.wikibase.cloud/wiki/Item:Q146 links back to the Wikidata item on the underlying publication https://www.wikidata.org/wiki/Q12217473.
Rather than create items locally for different countries, I use the Wikidata ID for the country: https://domains.wikibase.cloud/wiki/Property:P27. This is used to indicate on the "cdc.gov" item that it is a resource that comes from the United States https://domains.wikibase.cloud/wiki/Item:Q136#P27.
You can then use that Wikidata URI in a SPARQL query to identify other items annotated with that country value: https://domains.wikibase.cloud/query/#PREFIX%20wdt%3A%20%3Chttps%3A%2F%2Fdomains.wikibase.cloud%2Fprop%2Fdirect%2F%3E%0ASELECT%20DISTINCT%20%3Furl%0AWHERE%20%7B%0A%20%20%20%20%3Fitem%20wdt%3AP1%20%3Furl%20.%0A%20%20%20%20%3Fitem%20wdt%3AP27%20%3Chttp%3A%2F%2Fwww.wikidata.org%2Fentity%2FQ30%3E%20.%0A%7D.
This does not represent full interoperability between the two, but rather, how to get that baseline functionality. If I were to integrate it more deeply into Wikidata, I would do these two things:
(1) Create a combined query service with Wikidata and this dataset as well. Right now, if I want to incorporate Wikidata into my Domains Wikibase query, I need to know which exact Wikidata URI I am working with, or I would need to bring in the Wikidata Query Service as an external service within my SPARQL query (which is doable, but slower, plus you're liable to Wikidata Query Service timeouts if you don't have your own endpoint like I do). I would like to at some point operate a combined query service with these additional data sources but I haven't gotten around to creating it yet.
(2) Develop an interface extension to remotely load Wikidata statements on a local Wikibase. Internet Domains Wikibase, for example, has a sub item representing the English language https://domains.wikibase.cloud/wiki/Item:Q22240, a designated "exact match" of https://www.wikidata.org/wiki/Q1860. Such an interface extension would look up statements from Wikidata Q1860 and present them on the Internet Domains Wikibase item so that you don't have to leave that page.
I believe pulling Wikidata dynamically from the frontend, coupled with a combined query service, would be the most effective way to build a Wikibase that is a logical extension of Wikidata. If anyone is interested in making this happen, I am eager to discuss more.

Hi everyone.
On the topic of interoperability between Wikibase instance <> Wikidata, you might find this interview with the MiMoText team that we've recently published at the WMDE Tech News Blog to be of interest: Modeling the Enlightenment novel: an interview with the MiMoText team https://tech-news.wikimedia.de/en/2024/06/28/modeling-the-enlightenment-novel-an-interview-with-the-mimotext-team/
With very best wishes, Christos

If Wikidata is organized around concepts, this Wikibase is organized around domain names which are then linked back to their Wikidata ID. For example, you can see that the item for "cnn.com" < https://domains.wikibase.cloud/wiki/Item:Q146%3E links back to the Wikidata item on the underlying publication < https://www.wikidata.org/wiki/Q12217473%3E.
Rather than create items locally for different countries, I use the Wikidata ID for the country: < https://domains.wikibase.cloud/wiki/Property:P27%3E. This is used to indicate on the "cdc.gov" item that it is a resource that comes from the United States https://domains.wikibase.cloud/wiki/Item:Q136#P27.
You can then use that Wikidata URI in a SPARQL query to identify other items annotated with that country value: < https://domains.wikibase.cloud/query/#PREFIX%20wdt%3A%20%3Chttps%3A%2F%2Fdom...
.
This does not represent full interoperability between the two, but rather, how to get that baseline functionality. If I were to integrate it more deeply into Wikidata, I would do these two things:
(1) Create a combined query service with Wikidata and this dataset as well. Right now, if I want to incorporate Wikidata into my Domains Wikibase query, I need to know which exact Wikidata URI I am working with, or I would need to bring in the Wikidata Query Service as an external service within my SPARQL query (which is doable, but slower, plus you're liable to Wikidata Query Service timeouts if you don't have your own endpoint like I do). I would like to at some point operate a combined query service with these additional data sources but I haven't gotten around to creating it yet.
(2) Develop an interface extension to remotely load Wikidata statements on a local Wikibase. Internet Domains Wikibase, for example, has a sub item representing the English language < https://domains.wikibase.cloud/wiki/Item:Q22240%3E, a designated "exact match" of https://www.wikidata.org/wiki/Q1860. Such an interface extension would look up statements from Wikidata Q1860 and present them on the Internet Domains Wikibase item so that you don't have to leave that page.
I believe pulling Wikidata dynamically from the frontend, coupled with a combined query service, would be the most effective way to build a Wikibase that is a logical extension of Wikidata. If anyone is interested in making this happen, I am eager to discuss more.

Hello,
Our organization currently uses Wikidata subject terms for our taxonomy, but we apply them manually. We are researching setting up a Wikibase, but I am curious about the interoperability with Wikidata.
Does anyone have any examples of a Wikibase instance that is interoperable with Wikidata?
Thank you,
