So DSpace uses dublin core by the default and apparently you cannot touch that schema; since I am creating a collection of images, I want to create an IPTC schema. So I went to "Metadata" under Registries and clicked on "Add new schema". I named it and went ahead with adding fields. I've added a few to my first submission only to realize that they are essentially useless. I can't search with them. For example, if my dublin core title field says "Image a" but my IPTC title field says "John Smith", searching for John and/or Smith turns up nothing.
What is the appropriate way to make this a functional schema?
