The metadata information in the caDSR is developed by groups or organizations divided into domain-specific work areas called Contexts. A Context Administrator for each group provides oversight for creation, maintenance, and designation of CDEs within the Context. A list of contact of contact information for Steward/Context Administrators, Stewardship Organization/Curators and Embedded Curators (doc)  is is available.

The current Contexts in the caDSR are listed below with the Context Administrator for each (updated 0106/1229/2017).2021). Note - In the event the Steward/CA and/or SO/Curator leaves your organization, please contact the caDSR.RA@mail.nih.gov with new POC name and email if available.

The Context Administrators/Stewards work together to coordinate and harmonize metadata development efforts so common building blocks for data capture and reporting can be created. The goal is to ensure that shareable CDEs are not redundant across contexts and are based on the consensus of participating Contexts. To help minimize redundancy and duplication of CDEs across Contexts, the Context Administrators encourage reuse, or designation, of existing CDEs by other Contexts. Often an item is a candidate for reuse if minor edits can be made. If changes are needed to caDSR content, please contact the owning Context Curator.

The NCI, together with its partners in the user community, is actively developing CDEs and standard vocabularies to be used as metadata descriptors for NCI-sponsored research and for caCORE-NCI applications. Workgroup and Content Meetings are regularly held to identify subject areas for standardization, develop CDEs and supporting documentation, and present proposed data standards to the user community for review. The data standards that have been adopted and those currently under review may be seen on the caBIG®-NCI Data Standards page.
