Designer automatically creates an IRI for each class you create and uses some standard naming scheme for that. But is it possible to let it use a different one, that's linked to the model you're working on, so you can treat the model as an ontology?
When you select a class in Designer you can edit it's IRI, see below:
We will also soon be releasing some updates to our publishing workflow that will make management of your projects and their related artifacts a bit easier.
Thanks, I'd found that option. But using that, I have to enter the IRI for each and every class (and relation) I create. And I'm lazy, otherwise I wouldn't have ended up in IT. Thus my question about a kind of default setting. Will that be part of the publishing workflow?
Yes, you will be able to specify a default base, and everything will be relative to that within your project. And you will still be able to edit each individual resource to customize as you see fit.
