About caDSR

CBIIT’s management of metadata began as part of an effort to support CTEP’s reporting for breast cancer trials, and from a need to develop and disseminate standards that would ensure consistency and accuracy in reporting across the NCI Clinical Trial Network (NCTN/ETCTN) and Lead Protocol Organizations (LPOs). This led to the establishment of a centralized resource and associated web-based tools for creating, clearly documenting, and sharing human- and machine-readable data descriptions. The need to maintain and share data about data, or metadata, became the basis for the NCI’s repository of CDEs, metadata, and data standards, what is now known as the caDSR. A CDE Steering Committee was formed to define what kind of metadata was needed for the repository. Driven by the needs from community to create, share, and manage CDEs over time, a set of metadata attributes was established, which included attributes such as human friendly name(s), text definition(s), valid values, unique identifiers, and workflow status. Consultation with appropriate experts identified ISO 11179, an international standard for metadata registries, as meeting the needs identified by the CDE Steering committee. As time went on, more groups wanted to record their data elements and share them via the caDSR, so additional features were added, including extensions of ISO 11179 to enable storage of metadata describing Case Report Forms (CRFs) that use CDE metadata as the basis for questions on the CRFs.

  • caDSR Database and Tools
    Provides access to caDSR tools and links to the tool summary page for current user documentation and technical information like release notes.
  • caDSR Projects
    Focuses on specific projects. The pages include projects spanning across tools and products and projects involving inter-metadata registry sharing. For projects related to one specific tool, refer to the caDSR Database and Tools section.
    caDSR for Application Developers
    Focuses on the software interfaces to the caDSR available to programmers and software developers. The pages include details on the caDSR API, XML messages produced and consumed by the caDSR products and the caDSR UML Model.

  • caDSR Installation and Implementation
    Focuses on Open Source adoption of the caDSR Database and Tools. The pages include ISO 11179 implementation extensions, software implementation architectures and Downloads.

  • caDSR Future Requirements
    We continually look at new requirements and have an initiative begun in 2014 to replace the aging software and infrastructure currently supporting caDSR end users.  This is an opportunity to link our efforts more broadly with NIH wide CDE and metadata initiatives.  Please see the caDSR Requirements pages for more information.
