One of the central features in the ScienceBase Item Core Model is an integration of various types of people and organization contacts associated with items. Contact types designate a contact with a particular meaning. Currently, all contact types from both source materials and the needs expressed by individual communities are pulled together into a single contact types vocabulary. Should the list grow too large or complex, contact types will be broken out into individual code lists based on source and usage.
The current list of contact types can be access in the ScienceBase Vocabulary under item/contact/type here.
