Attempting to download all the caDSR CDEs would result in a file size that is too large for a single MS Excel download, and currently forms can only be downloaded one form at a time.
Therefore, "canned", or pre-downloaded collections of all the NCI Standard CDEs, and "Released" CDEs, and CDEs by selected individual projects in is provided for your convenience.
Therefore, "canned", or pre-downloaded collections of all the NCI "Released" CDEs, and CDEs by selected individual projects in is provided for your convenience. The NCI Preferred Standards have become too large to download in a single file, so they can be extracted from the "Released" CDE files.
Note that NCI added an FTP site where all "Released" CDEs as XML.
If importing caDSR content from a download into another ISO/IEC 11179 or other similar CDE or CRF metadata registry, please add the caDSR Registration Authority Identifier (RAI) 2.16.840.1.113822.214.171.124 to the metadata to keep the caDSR content distinct from the local repository. Per ISO/IEC 11179, the RAI is part of a globally unique identifier known as the IRID (Item Registry Identifier), and uniquely identifies registry content as being related to particular registrars. The IRID for all caDSR content is the <caDSR OID + Item public Id + item version>. For example, if the caDSR item public id = 2181292, version = 1.1, when importing you would add the RAI, and the result would be an IRID = 2.16.840.1.1138126.96.36.199 + 2181292 + 1.1.
