FDA Adds CDISC ODM Define.xml to Study Data Specifications

The FDA has now included the CDISC Case Report Tabulation Data Definition Specification (define.xml), which is based on the CDISC ODM, as part of the eCTD Study Data Specifications for the eCTD for submissions using the SDTM. The revised specifications are available at http://www.fda.gov/cder/regulatory/ersr/ectd.htm.

Case Report Tabulation Data Definition Specification (CRT-DDS, also called define.xml)
Final Version 1.0

CRT-DDS Released for Implementation February 10, 2005.

The CDISC define.xml Team has published the Case Report Tabulation Data Definition Specification (define.xml) Version 1.0 for implementation, which supersedes all prior versions. Version 1.0 reflects changes from a comment period through the Health Level 7 (HL7) Regulated Clinical Research Information Management Technical Committee (RCRIM) in December 2003 (www.hl7.org) and CDISC's website in September 2004 as well as the work done by the define.xml team in conjunction with the CDISC ODM team to add functionality, features, and additional documentation.

This document specifies the standard for providing Case Report Tabulations Data Definitions in an XML format for submission to regulatory authorities (e.g., FDA). The XML schema used to define the expected structure for these XML files is based on an extension to the CDISC Operational Data Model (ODM).

The 1999 FDA electronic submission (eSub) guidance and the electronic Common Technical Document (eCTD) documents specify that a document describing the content and structure of the included data should be provided within a submission. This document is known as the Data Definition Document (e.g., "define.pdf" in the 1999 guidance). The Data Definition Document provides a list of the datasets included in the submission along with a detailed description of the contents of each dataset. To increase the level of automation and improve the efficiency of the Regulatory Review process, define.xml can be used to provide the Data Definition Document in a machine-readable format.

Filename Description
CRT_DDSpecification1_0_0.pdf
Case Report Tabulation Data Definition Specification (define.xml), Version 1.0.
define1-0-0.xsd The define.xml schema version 1.0.
This schema “glues” the extensions and the ODM together to create the full define.xml definition.
Applications implementing define.xml should reference only the define1-0-0.xsd directly.
define-extension.xsd This schema defines where in the ODM the define.xml extensions should appear.
define-ns.xsd This schema defines the elements and attributes that are included in the define.xml extensions to ODM.
SchemaFiles.zip A ZIP file that includes all of the schema related files only (define1-0-0.xsd, define-extension.xsd, and define-ns.xsd).
define1-0-0.xsl An initial define.xml style sheet (Version 1.0) that is compliant with XSLT Version 1.0 specification (1999). Future releases of the style sheet will expand the available functionality and features.
Example 1: define.xml An example of the data definition document in XML without a style sheet reference.
Example 2: define.xml An example of the data definition document in XML with a style sheet reference.
ExampleFiles.zip A ZIP file that includes both examples, including all referenced external files for the 2nd define.xml example (e.g., define1-0-0.xsl, sample SAS Version 5 Transport Files, blankcrf.pdf, and supplementaldatadefinitions.pdf).
CRT_DataDefinitionFiles.zip A ZIP file that contains all of the files referenced above (excluding the above zip files).
To insure the latest copy of the define.xml specifications and supporting materials, users should 1) check the CDISC website for news related to new versions of the define.xml specifications, style sheet or support documentation, and 2) compare the website posting date with their file download date and update when necessary
