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.
The single, trusted, authoritative source of CDISC standards metadata, CDISC members can leverage CDISC Library via a Data Standards Browser or API to:
- Access and easily browse multiple versions of Foundational Standards' metadata and Controlled Terminology
- Retrieve standards metadata in JSON, XML, ODM, CSV, Excel
- Create Diff Reports, which deliver machine-readable (JSON, Excel) metadata comparisons that compute and display differences between normative content in two versions of a standard.
- View Draft Content to test upcoming standards' releases in your systems.
Additional benefits include:

Listed below are the available CDISC standards and terminology. This page will be periodically updated to reflect new released content.

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.
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.
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, 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."
}
