That's my impression too:

The WikiPathways SPARQL endpoint URL has changed, and I have requested an
update (Jan 2020, [0]), but no update or reply yet.

Maarten, that is causing the simple query in this report to fail.

Hi, do you like citation networks? Already 51% of all citations are
available  available for innovative new uses
. Join me in asking the American
Chemical Society to join the Initiative for Open Citations too
.
SpringerNature,
the RSC and many others already did .

Re: [Wikidata] Qualifiers/sources for YSO authority links

[Osma Suominen]

Thanks for the advice Denny!

We've now created two web pages that describe the work we do linking YSO 
and Wikidata:


In English: https://www.kiwi.fi/x/SYO_CQ
In Finnish: https://www.kiwi.fi/x/cIK_CQ

So following your suggestion, I will now create a Wikidata item for 
"Project for linking YSO to Wikidata" or something along those lines. 
The item could then link to the above URLs (using which property?).


Then in the actual YSO ID statements (which are many), the newly created 
WD item would be referred to as the source.


Does this make sense or did I get it wrong?

Yes, that sounds good to me.

Either create an item for that (preferred) or link to the URL directly.

Thanks Denny.

Do you have a practical suggestion how to do this? There's no obvious
source URL to refer to currently. What Joachim did was to set up a
small
document on GitHub and refer to that in the statements. Should I do
something similar here?

I created https://phabricator.wikimedia.org/T249041 for this. The 
Wikimedia site requests is one of the more active boards in my 
experience. Let's see how it goes. If it goes well, we can just start 
moderating 
https://www.wikidata.org/wiki/Wikidata:SPARQL_federation_input and 
create a site request for everything that gets approved.
