COMMENTS DUE NOVEMBER 9, 2015 - bioCADDIE DDI Identifier Recommendations

WG2 DDI Identifier Recommendations

Deadline for Public Review and Comment:  November 9, 2015



Working Group final version released for public comment 30 October 2015.


This document is meant to review identifier practices in the context of the bioCADDIE Data Discovery Index (DDI) prototype. The goal of this document is to provide the bioCADDIE Core Development Team the necessary guidelines and operating procedures to produce a functional prototype that enables data discovery and facilitates data sharing and re-use of data found within data repositories and the NIH Commons.

Scope of Identifier Recommendations

The identifier recommendations contained within this document are focused on the need for the DDI to uniquely identify data sets within biomedical data repositories and the NIH Commons. Other aspects of identifiers were deemed out-of-scope for this document. Data citation, for example, is already being addressed by many groups, including the FORCE11 Data Citation Implementation Group which is building on the Joint Declaration of Data Citation Principles. The DDI, similar to PubMed, must reference the appropriate citable identifier provided by the data set maintainer.

Intended Audience

This document is primarily aimed at the bioCADDIE Core Development Team that is implementing the bioCADDIE prototype; however, this document may also be informative for other groups, such as those involved with the NIH Commons, community aggregators, and developers of data harvesting and other tools.


In the context of the NIH BD2K bioCADDIE project, we aim to provide recommendations for the appropriate handling of identifiers for datasets and data repositories (repository as used in this report refers to a source of data/datasets) within the bioCADDIE prototype. This document was generated from the discussions of bioCADDIE Working Group 2. During these discussions, a number of identifier related topics were described as being out-of-scope for the current work of this working group – many of these topics potentially relate to the work of other active or future bioCADDIE working groups or broader community working groups.
