Metadata Publication and Access Working Group (MPAWG)

Purpose: This working group aims to promote the machine-actionable publication and standardized access to DDI metadata in support of the FAIR data principles. By encouraging the visible use of DDI standards—such as DDI-Codebook, DDI-Lifecycle, and DDI-CDI—the group seeks to enhance the adoption and impact of DDI across the data community.
