Newline characters, i.e.,
\n, in JSON media type outputs are not present in the XML media type outputs.
Data Standards Browser
NEW The following indexed entries are erroneous for when scope is '
class'. This impacts search results using both API endpoint and Data Standards Browser. It has no content impact to the underlying SDTM metadata. CDISC will look into patching this issue in future updates.
Note: Queries using scope search are also affected, e.g.,
Currently, the JSON object
_links/priorVersion is part of the API response when querying codelists and terms belonging to the earliest CDISC Controlled Terminology package loaded into the metadata repository. CDISC is working to address this so that
_links/priorVersion will be removed from the API response in this case.
CDASH products contain mapping information to target variables in the SDTM and the SDTMIG. These targets do not always exist in their associated SDTM and SDTMIG product's class or domain specification tables; therefore, these targets are not available in the metadata repository. An example is the CDASHIG variable ECVAMT, where ECVAMT is not present in the SDTMIG v3.2 EC domain specification table. CDISC is working with the standards development teams to identify a resolution.
The Supplemental Qualifier dataset’s variable definitions are not instantiated for any general observation class dataset in any of the SDTMIG publications. Therefore, all CDASH variable mappings that involve a domain-specific Supplemental Qualifier target (SUPP--) are generalized. For example, SUPPCM.QVAL is referenced as SUPPQUAL.QVAL. CDISC is working with the standards development teams to identify a resolution.
Variable order (i.e., ordinal) is a numeric property in the metadata repository. In cases where they are not numerical in the published CDASH standard, variables are reassigned a value that preserves their original sequence in the documentation. Example, "10a", "10b", "12a", "12b", etc. for variables in the CDASH v1.1 AE domain where reassigned values of "10", "11", "13", "14" and so on.
CDISC is working with the standards development teams to identify a resolution.
For CDASHIG v1.1.1, domain and scenario fields do not have the
title component in the hypermedia links, i.e.,
_links/self/title. This is due to the lack of variable label metadata in the original published standard. This metadata gap is resolved in CDASHIG 2.0. For example, an excerpt from CDASH v1.1.1's CMTRT using
In contrast, this is an excerpt from CDASH v2.0's CMTRT using
/mdr/cdashig/2-0/domains/CM/fields/CMTRT, where the
title component is present in the hypermedia links:
NEW title is not available within the hypermedia link for CDASH Model v1.1's AP-- domain due to lack of such metadata in the CDASH Model v1.1 publication.
By the same token, label is not available in the response body of this API request:
SDTM & SEND
The Supplemental Qualifier (SUPPQUAL) dataset is not instantiated for any general observation class datasets in any of the SDTMIG publications. In other words, there is only one SUPPQUAL dataset for each version of the SDTMIG and the SENDIG. CDISC is working with the standards development teams to identify a resolution.
NEW The hypermedia link about parent product is omitted from these API endpoints. In other words, the JSON path
$._links.parentProduct does not yield any results:
NEW For both SENDIG v3.1 and SENDIG-DART v1.0, the CDISC Library has the described value domain "ISO 21090 NullFlavor enumeration" attached to the TSVALNF variable. It is different from the intention to use a SEND Controlled Terminology codelist due to a typographical error. NULLFLAV is the SEND CT codelist shortname. However, it is erroneously listed as "(NULLFLAVOR)" in the SENDIG v3.1 publication. CDISC is working to address this with the SEND team.
NEW For SENDIG v3.1, a portion of the CDISC Notes for the variable MISTRESC is missing in CDISC Library. The missing portion is "Neoplastic findings must be populated using the NEOPLASM controlled list."
ADaM & ADaMIG
For ADaM TTE v1.0, the response of this API query
/mdr/adam/adam-tte-1-0/datastructures shows Basic Data Structure for Time to Event Analyses (ADTTE) as a data structure.
In data modeling, ADTTE is a specialized form of the BDS data structure. CDISC is working with the standards development teams to apply this modeling concept into applicable foundational standards.
NEW For ADaM OCCDS v1.0, these hypermedia links about prior version of the OCCDS data structure are malformed. The href value is incorrect, causing title and/or type missing:
