Does metadata in CDISC Library match those in the publications? Does it contain corrections?

CDISC requires metadata in CDISC Library to match what is originally published. CDISC uses automated tools to take the metadata from the specifications in the publications and put it into CDISC Library. The CDISC Library Release Notes describe where there are exceptions and/or limitations. CDISC is working to ensure that known issues in the published standards are addressed.

Which part of a published standard is available in CDISC Library?

CDISC Library contains highly structured content such as domain specification tables from the SDTM, SENDIGs and SDTMIGs, metadata tables from CDASH and CDASHIG, data structure variables from ADaMIGs, and Controlled Terminology quarterly publications.

Why does this query fail /mdr/sdtm/1.6?

CDISC Library uses dashes for version. There is no v or V. /mdr/sdtm/1-6 is the correct query construct.

Why does this query fail /mdr/sdtmig/3-2/classes/?

The trailing forward slash is extra, which causes the error. /mdr/sdtmig/3-2/classes is the correct query construct.

Why does this query fail /mdr/SDTM/3-3?

Path parameters are case sensitive. /mdr/sdtm/3-3 is the correct query construct.

What information can I use to help diagnose a failed query?

An HTTP status code is always returned after the server finished processing a request. CDISC Library API generally follows HTTP/1.1's guidelines for status code. For example, 200 indicates a successful request. When a query is not successful, with status code in the 4xx and 5xx series, a message will appear in the response body. For example, when requesting a fictitious version of SDTMIG, sdtmig-5-0:

HTTP/1.1 404
status: 404
Date: Wed, 29 May 2019 23:46:19 GMT
Content-Type: application/json
{
   "message": "Service resource error.",
   "detail": "Requested resource [http://library.cdisc.org/sdtmig-5-0/Product] does not exist."
}
