Data Standards

caBIG® Data Standards

Common Data Elements (CDEs) are annotations collected in a uniform manner across multiple institutions, allowing the sharing of data in a standardized format. To date, over 20 CDEs have been accepted for use by the caBIG® Community as Data Standards. To view a list of caBIG® accepted Data Standards, click on the link below for the list in alphabetical order.

Data Standards Process

Development and Governance Process  [February 2010]

The governance process for identification of standard Common Data Elements (CDEs) to be used in caBIG® is described graphically in a caBIG® CDE Governance Process diagram. The process includes the conceptualization and development of Proposed Standard CDEs, review and approval of Candidate Standards by the caBIG® Vocabularies and Common Data Elements (VCDE) Workspace, and periodic review and maintenance of the Standard CDEs. Registration status is used to track progress from a Proposed standard, to a Candidate standard, and then to a Standard approved for use by the caBIG® community.

A current list of CDEs under consideration for caBIG® Data Standard status can be found by using the caDSR Browser (CDEBrowser). Data Standards are registered in the caBIG® context under Classifications in the Browser tree and presented by registration status of Proposed, Candidate, and Standard.


Candidate caBIG® Data Standards/Modifications Under Review

There are currently no reviews. There is a harmonization activity for the existing CDEs in the caDSR that is owned and led by the Dianne Reeves and the content curators.
