CDISC-ODM

Experimental

CDISC-ODM conversion is still experimental. It only works with controlled exports from REDCap projects.

CDISC stands for Clinical Data Interchange Standards Consortium. ODM stands for Operational Data Model.

CDISC is an organization that develops standards for data exchange of clinical research. From their standards, we accept the Operational Data Model (ODM)-XML as input as it is widely used for representing forms for case-reporting in many electronic data capture (EDC) tools.

About ODM-XML

ODM-XML is a vendor-neutral, platform-independent format for exchanging and archiving clinical and translational research data, along with their associated metadata, administrative data, reference data, and audit information.

CDISC-ODM as input

Command-line

ODM versions

We're accepting CDISC-ODM v1 (XML). Currently, v2 is in the process of being approved.

We'll need three files:

1. CDISC-ODM v1 (XML)
2. REDCap data dictionary (CSV)
3. Mapping file (YAML or JSON) (see tutorial)

convert-pheno -icdisc cdisc.xml --redcap-dictionary dictionary.csv --mapping-file mapping.yaml -obff individuals.json

About other CDISC data exchange standars

We are currently exploring Dataset-XML (extension of ODM-XML) and the new Dataset-JSON formats. The idea is to support them in the future.
