Does this depend on the WIRIS web service

Hi there! Good question, I'm actually not 100% sure. I did spot the following though:

This npm module uses remotely hosted services to render MathML data. In case of wanting to install these services on your own backend, please contact support@wiris.com.

Source: https://www.npmjs.com/package/@wiris/mathtype-ckeditor5#user-content-ser...

In my very quick testing I did see multiple outgoing request to
- https://www.wiris.net/demo/plugins/app/configurationjs
- https://data.wiris.cloud/telemetry/v1
- https://www.wiris.net/demo/editor/editor?lang=[object%20Object]&stats-ed...
- https://www.wiris.net/demo/hand/hand.js?httpstatus=true
...

So I guess the answer is yes. There are options to self host things going from the documentation, but you seem to need a license for that as well.

Which also raises the question to me I still don't understand how the licensing is being handled for Wiris. I only adopted the module to make it D9 compatible and now D10 :) but I was not part of the "core development" of the module. So still have to figure things out about that aspect.

Thankyou @BramDriesen, good pointers.

Reading this...

Do you think that is referring to the eventual Drupal rendered page or, I seems sensible to me, only for rendering the MathML in the pane within the editor itself.

This is a crucial consideration for us because, as stated, the WIRIS CKEditor plugin is not responsible for site rendering, we use MathJax for that that and so we really don't want yet another dependency loaded in the front end for site visitors if we don't really need it.

It also begs the question if we use MathJax in the front end, why not use it in the editor's rendering pane too?

The only dependency the Drupal module declares is: "@wiris/mathtype-html-integration-devkit" which is not requiring anything really beside what is already in Drupal: https://github.com/wiris/html-integrations/blob/stable/packages/ckeditor...

I did not have to add the MathType script in order for it to render, so I guess this is included by the plugin somehow. I do believe this is also using MathJax actually. But not 100% sure on that.

To follow up further,

Installing the module on a local development site results in it working happily working...

When pushed onto a live-dev (hosted) site...

This pretty quickly becomes...

I have managed to successfully negotiate free access for our non-profit educational site and I have been told that 'an adjustment' has been made WIRS' end and that the trial status will disappear soon.

I will keep you up to date.

How does the licensing actually work? Do they need to whitelist your site or something? Never really figured that part out.

As for the rendering, it currently does look a bit different between the back-end and the front-end.

It looks like it's currently just HTML that is trying to do it's best at rendering this. I guess if you have a dependency installed like MathJax or MathType the rendering looks different.
