How will Knora or Sipi find resource class icons? about dsp-api

The icons can all be served directly by Sipi, using a IIIF URL.

We just need to be sure that every icon that is used by Knora exists on the Sipi server. We could use a special prefix for that.

Strictly speaking, aren't ressource class icons something that the gui (Salsah) would need to take care of? Salsah can have a default mapping of ressource classes to icons, which then could be changed in the project specific settings.

I think this is a good way to do it! So then we would place the icon files in the salsah-app?

[subotic]

Yes, that's what I was thinking. For now we could create a folder under app/icons and put all resource class icons inside it. Then somewhere in Salsah, we will need to define the mappings between the classes and the icons. Later on, these default icons could then be changed by adding custom project specific themes to Salsah, or something like this.

Now, I added a function that creates URLs for resource icons: e2a141b

It takes the Iri of a resource class and gets out the name of the ontology it was defined in. Then it is expected that the actual icon is in a folder with that name in Salsah's icon project folder: http://localhost:3335/project-icons/incunabula/page.gif
