CDISC Library uses linked data and a REST API to deliver CDISC standards metadata to software applications that automate standards-based processes. CDISC Library provides access to new relationships between standards as well as a substantially increased number of versioned CDISC standards and controlled terminology packages.
CDISC Library is the single, trusted, authoritative source of CDISC standards metadata and represents a new way of creating, maintaining, and publishing this metadata.
Additional benefits include:
Listed below are the available CDISC standards and terminology. This page will be periodically updated to reflect new released content.
CDISC Library API Account Request
Thank you for your interest in the CDISC Library API. Free access is a benefit of CDISC Membership.Product Inquiry Form to learn about CDISC Membership or fee-based options to access the CDISC Library API.
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.
CDISC Library uses dashes for version. There is no v or V.
/mdr/sdtm/1-6 is the correct query construct.
The trailing forward slash is extra, which causes the error.
/mdr/sdtmig/3-2/classes is the correct query construct.
Path parameters are case sensitive.
/mdr/sdtm/3-3 is the correct query construct.
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,
Date: Wed, 29 May 2019 23:46:19 GMT
"message": "Service resource error.",
"detail": "Requested resource  does not exist."
For a list of supported HTTP status codes, visit https://wiki.cdisc.org/display/LIBSUPRT/HTTP+Status+Codes.
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 (https://www.getpostman.com), SoupUI (https://www.soapui.org), and Insomnia (https://insomnia.rest).
