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?

The content from Foundational Standards that is highly structured with predictable patterns is available in CDISC Library. For example, domain specification tables from the SDTM and SDTMIGs, metadata tables from CDASH and CDASHIG, data structure variables from ADaMIGs, and Controlled Terminology quarterly publications.

How does authentication work?

The CDISC Library API supports queries made using HTTPS scheme. When they are made using HTTP however, the server redirects the queries to HTTPS unless an application client is configured not to automatically follow the redirect. In this case, an HTTP 301 status code (i.e., Moved Permanently) will be the result.

In terms of authorization method, Basic Auth is supported.

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 [] does not exist."

I use a web browser to submit a query. Where can I find the HTTP status code mentioned above?

An HTTP status code is part of the response header when receiving a response from the server. Consult the web browser's manual on how to view this information.

Web browsers are a great tool to grasp the basics of CDISC Library API. API development and testing tools will be useful when building an application. There are plenty free and open-source options in the marketplace. A few suggestions are: Postman (, SoupUI (, and Insomnia (
