I have tried different options but I am starting to wonder if it is even possible. Our omeka install contains differents item-sets that have been inherited from the collections of our omeka classic install.
I’d like to take advantage of migrating to omeka-S to merge some of them. Internally it makes sense that they are in differents item-sets but on the public side I’d like to have only one item-set displayed, as on my home page I show all the pubic item-sets.
So basically what I wanted to do was to create an item-set defined as the combination of the pre-existing sets, that would therefore contains the sum of all the items of the previously existing item-sets.
Is this even possible?
