From Damaris at Duke: I am trying to understand how the terms “publication” and “activity” are being defined/used on the beta.vivosearch.org browse page? These terms don’t appear to be defined in the ontology and I’m wondering if there are a set of attributes identify a publication or activity? I see some items (ex. Grants, projects) are being classified as both a Publication and an Activity. For other items (ex. Human Study, Process, Project, Program, Subject Area), it’s not clear to me what makes them Publications?
