One of OBI’s key goals is to enable researchers to collaborate across disciplines, across institutions and across disorders. OBI has established standards to help improve data quality and make data FAIR (findable, accessible, interoperable, and reusable).
Data Quality
OBI has developed a Data Quality Framework (DQF) to support quality data collection and generation. The Data Quality Framework documents can be accessed here:

Standard Protocols and Consent Language
In order to collect data on Brain-CODE, data producers must adopt the standard consent language and protocol language in their consent forms and protocols. The following are available here:
Generic Consent Language for Brain-CODE (Jun 15, 2025)
Brain-CODE Generic Schematic (May 14, 2014)

Common Data Elements
Enabling researchers to collaborate across disciplines, across institutions and across diseases has the power to drive research discoveries like never before. To help achieve this level of collaboration, Brain-CODE Common Data Elements (CDEs) have been developed to provide standard definitions and formats so that researchers collect data consistently across studies. This will reduce variability in data collection and ultimately facilitate comparisons across diseases, merging of datasets, and meta-analyses.
Learn more about Brain-CODE's standardization approach.
The table below provides links to the Brain-CODE’s CDEs, including the instruments and data dictionaries.
