Using Metadata for Speedy Delivery

Summary: In this R Adoption Series Webinar, the R Consortium invited two Pharmaceutical organizations to share their experience in leveraging metadata for automation pieces of the clinical delivery workflow. This session starts with Christina Fillmore using Open Source R packages {metacore} and {metatools} for creating metadata objects and enhancing columns in existing datasets. Following Christina, Yujie Zhao and Keaven Anderson will discuss {metalite} which is used to define a unified data structure to save metadata information for analysis & reporting (A&R) based on ADaM datasets in clinical trial development. The last section of the event will be focused on answering questions about leveraging metadata in the delivery pipeline and soliciting other ways to use metadata to enhance current processes
