Welcome to the SEND Implementation Wiki!

The SEND Implementation Wiki is a knowledge base on implementing SEND - a series of articles designed to help you understand and implement SEND, including modeling basics, useful links, FAQs, and more.

In addition to the wiki, the companion SEND Implementation Forum is a place for active discussion and to ask questions not already answered in the wiki.

What Is SEND?

SEND, or the Standard for Exchange of Nonclinical Data, is an implementation of the CDISC Standard Data Tabulation Model (SDTM) which specifies a way to present nonclinical data in a consistent format.

By having a common model to which the industry can conform, many benefits can be realized, such as inter-company exchange that is consistent in format regardless of the parties involved, the ability for vendors to develop tools, and many others.

A SEND package consists of a few parts, but the main focus is on individual endpoint data. Endpoints typically map to domains (essentially, datasets), with a number of variables (a.k.a., columns or fields).
