The DwB Resource Discovery Portal (DwB-RDP) provides mechanisms to researchers and applications to search and retrieve metadata for the catalogued datasets. It currently allows search at the study level. The portal user interface consists of three separate views, the discovery portal home page, the search results page, and the study details page.
The DwB-RDP is built on a metadata model starting from DDI as a representation of community best practices and standards in metadata development. To harvest and register information into the portal repository, both development lines of the DDI (Codebook and Lifecycle) are identified as core specifications.
