Okay, I think I see what you meant now.

My first test did not work, but that's because the scholia.js still uses internally hardcoded (unconfigurable) URLs. But I can work with this.

Example scholia.ini:

[query-server]
# QLever
#sparql_endpoint = https://qlever.cs.uni-freiburg.de/api/wikidata
#sparql_editurl = https://qlever.cs.uni-freiburg.de/wikidata/?query=
#sparql_embedurl = 

# OpenLink (Virtuoso)
#sparql_endpoint = https://wikidata.demo.openlinksw.com/sparql/
#sparql_editurl = 
#sparql_embedurl =

# Wikidata:
#sparql_endpoint = https://query.wikidata.org/sparql
#sparql_editurl = https://query.wikidata.org/#
#sparql_embedurl = https://query.wikidata.org/embed.html#

# Wikidata Split Main
sparql_endpoint = https://query-main.wikidata.org/sparql
sparql_editurl = https://query-main.wikidata.org/#
sparql_embedurl = https://query-main.wikidata.org/embed.html#

# Wikidata Split Scholar
#sparql_endpoint = https://query-scholarly.wikidata.org/sparql
#sparql_editurl = https://query-scholarly.wikidata.org/#
#sparql_embedurl = https://query-scholarly.wikidata.org/embed.html#

I am trying to understand this. As far as I can determine you do not have polymorphic functions in Javascript, so the second definition of sparqlToResponse will overwrite the first one? Or what am I missing?

[fnielsen]

$ node -e "function f(a, b) { console.log('two arguments'); } function f(a) { console.log('one argument'); } f(1, 2);"
one argument

[egonw]

@fnielsen, good catch. Are you okay to name the new one sparqlToResponse2? If not, what name should it be?

@fnielsen, what do you think?

Okay, we have to start moving. We have less than 6 months left.

Hi all!

As part of the WDQS Graph Split project,[1] we have new SPARQL endpoints available for serving
the “main”[2] and “scholarly”[3] subgraphs of Wikidata.

As you might be aware we are addressing the Wikidata Query Service stability and scaling issues.
We have been working on several projects to address these issues. This announcement is about one
of them, the WDQS Graph Split.[1] This change will have an impact on certain uses of the Wikidata
Query Service.

We are now entering a transition period until the end of February 2025. The three SPARQL endpoints
will remain in place until the end of the transition. At the end of the transition,
[query.wikidata.org](http://query.wikidata.org/) will serve the main Wikidata subgraph (without
scholarly articles). The query-main and query-scholarly endpoints will continue to be available after
the transition.

If you know to want more this change, please refer to the talk page on Wikidata.[4]

Have fun!

Oh, I did write up how to use this patch, but forgot to add the link here: https://chem-bla-ics.linkedchemistry.info/2024/08/23/scholia.html
