In order to facilitate data sharing and unambiguous interpretation of data between different researchers, it is imperative to share a common vocabulary. You are required to use controlled vocabulary for some of the fields in the CUAHSI Formatting Template. CUAHSI maintains a community-driven, staff-moderated set of controlled vocabularies for the Observations Data Model (ODM). The Controlled Vocabulary website is organized by metadata field so you can find the correct vocabulary as you fill in your formatting template. To request new or updated terms, navigate to the associated controlled vocabulary page and click New on the top of the table as shown below. Fill out the form and CUAHSI will get back to you shortly.
