The purpose of CEDAR is to improve metadata and its use throughout the biomedical sciences. These pages describe the project's intentions in more detail.
User Personas are roles that people take on as part of their job. For example, a biologist may act as a lab manager, a data analyst, a lab technician, and a teaching professor in the course of a single day.
In software development, User Personas are used to describe the target users for the delivered system and its products. In simple cases, each user persona can be briefly titled and described; more advanced systems benefit from having detailed descriptions of hypothetical users, reflecting all their user personas and relevant personal interests and characteristics.
