 Note: Before you add any types of your own, there should be a single type called "dataset". If you add "software" or "workflow", these types will be sent to DataCite (if you use DataCite). Otherwise, the only functionality you gain currently from adding types is an entry in the "Dataset Type" facet but be advised that if you add a type other than "software" or "workflow", you will need to add your new type to your Bundle.properties file for it to appear in Title Case rather than lower case in the "Dataset Type" facet.
