The document outlines the agenda for a presentation on the MISSY microdata information system, focusing on various aspects such as variable information, data preparation, and the MISSY editor. It highlights issues related to DDI 3, including a lack of general information and concerns about nested concepts. The presentation also invites discussion and questions regarding the system and its use.
