wikidata | Simple Ruby client for Wikidata

I have a REST API of classical actors that I want to visualize in Postman. The image URL of an actor is not in the API, so I will need to create a mashup from a combination of the core API and another API.

The core API/endpoint is at http://henke.atwebpages.com/postman/actors/actors.json:

I am new on this side, the question-asking side, so please tell me if you need any additional information.

I have a dataset with 2900 entries consisting mostly Dutch and Flemish poets. I want to add information to this dataframe by querying wikidata; gender, nationality, day of birth, day of death. Now how many poets can two small countries have? Not all of them are to be found on wikidata (I'm going to take care of that later), and for the ones that are, the info is sometimes very scarce.

I have used the following query:

I'm trying to parse this .txt file in R: https://ftp.expasy.org/databases/cellosaurus/cellosaurus.txt

It's essentially a single column data frame of some ~2 million rows, with each entity being described by multiple rows and bookended by rows containing the string "//".

Ideally, I could capture each entity, made up of multiple rows, as a list element by splitting at "//", but I'm not sure of the most efficient way to go about this.

Any help is much appreciated.

EDIT:

Here's a snippet of what I'm working with:

I am trying to recreate this list:

https://en.wikipedia.org/wiki/List_of_states_and_territories_of_the_United_States_by_GDP

with a Wikidata SPARQL query.

I can find states by population with this query

Additionally, the fields:

• population (P1082)
• GDP (P2131)
• And some extra ones, like unemployment (P1198)

are covered by the wikiproject economics, though only at the country level.

That said, seeing the "List of states and territories of the United States by GDP" article makes me think at least P2131 may be available at the state level.

I have tried the following query.

I have the following query:

I am running an Apache Jena Fuseki server als the SPARQL endpoint that I can connect to when using the application normally. Everything works and I get the output from the resulting query.

But When I try to run my test with Springboot, Junit5 (I assume) and MockMVC it always get stuck on the following part:

I create directed graphs like the following from wikidata with the help of networkx and nxv. The result is an svg file which might be embedded in some html page.

Now I want that every node and every edge is "clickable", such that a user can add their comments to specific elements of the graph. I think this could be done with a modal dialog popping up. This dialog should know from which element it was triggered and it should send the content of the textarea to some url via a post request.

What would be the best way to achieve this?

I want to login to Wikidata using their API: https://www.wikidata.org/w/api.php

I had prepared a few requests and tried them against the test instance of Wikidata: https://test.wikidata.org/w/api.php. Everything worked fine and I changed the call to target the real Wikidata instead. But now the action clientlogin won't work, even though the settings are exactly the same as for the test instance. I have looked for documentation, but none seem to describe any differences between the test and the real instance.

I'm using Postman for making the POST requests. I have the parameters:

I'm looking to recreate this list of cities in Texas by population using wikidata.

I see I can do states by population with this query:
