The NCI caDSR CDE Browser can be used to download collections of metadata describing data held in repositories for cancer research and clinical trials.

The caDSR Form Builder can be used to create, view and download the Case Report Forms (CRFs) designs.

Currently, CDEs can be downloaded in Excel or XML Format, CRFs can be downloaded in Excel format.

Since it may not be easy for occasional or novice users of the CDE Browser and Form Builder to discover collections of CDEs or CRFs, since the high level organization of CDEs and Forms in the Navigation Tree is by Context, which correlate to user communities, not CDE topic. After selecting a Context in the caDSR navigation tree, one can browse the Classifications, which represent user defined collections of CDEs for specific purposes, but this may not be intuitive. Some find the use of the Advanced Search helpfulwhich also offers a text search by Classifications namesModernization of the caDSR content access services is plannedThere are currently no NCI Recommended CDEs for use other than the  CDEs marked as having a Registration Status of "Standard".  Any CDE in caDSR can be reused, but the ones marked "Standard" have been through a broader governance process. There communities within NCI who have agreed to use a set of CDEs for specific purposes, for example EDRN, TCGA, NCTN, and many others.  If you wish to collect data that is compatible with a specific group, you should begin by looking for the group's CDEs using the CDE Browser.  The Context name is an organizing principle for tree based navigation, and the "Advanced Search" provides a way to search for CDEs grouped by Classifications, or keywords.
