In this presentation, we will discuss the Data Documentation Initiative (DDI) standard for describing the data produced by surveys and other observational methods in the social, behavioral, economic, and health sciences.
We will spend the bulk of our time highlighting DDI-Codebook and DDI-Lifecycle. DDI-Codebook is a more light-weight version of the standard, intended primarily to document simple survey data. DDI-Lifecycle is designed to document and manage data across the entire life cycle, from conceptualization to data publication, analysis and beyond.
It encompasses all of the DDI-Codebook specification and extends it to more complex, linked, and longitudinal data. Based on XML Schemas, DDI-Lifecycle is modular and extensible.
We will also briefly discuss the DDI Alliance organizational structure, as well as products currently under development. 1) To understand DDI-Codebook, including when and how to use it. 2) To understand DDI-Lifecycle and an applied example. 3) Learn how the DDI Alliance organization maintains the DDI metadata standard.
