CBIIT or Stakeholder Organization

The purpose of this document is to collect, analyze, and define high-level needs and features of the National Cancer Institute Center for Biomedical Informatics and Information Technology (NCI CBIIT) BRIDG 2.1 Release. This document focuses on the functionalities proposed by the product stakeholders and target users in order to make it a better product. The use case and supplementary specifications document will detail how the framework will fulfill these needs.

Vision and Needs

The Biomedical Research Integrated Domain Group (BRIDG) recently announced the release of version 2.1 of BRIDG. This version incorporates several new capabilities focused on representing the people, organizations, and core components describing clinical trials protocols. These changes include compatibility with the World Health Organization (WHO) and clinical trials registries, and much better modeling of the protocol abstraction itself. Together these changes simplify the collection, analysis and comparison of standards-based clinical trials data between sites and between different trials.

BRIDG is a domain analysis model that facilitates semantic interoperability between standard data models and service data objects (SDO) like those developed by CDISC, HL7, and ISO. BRIDG has been developed collaboratively by a community that includes the Clinical Data Interchange Standards Consortium (CDISC), the HL7 Regulated Clinical Research Information Management Technical Committee (RCRIM TC), the US Food and Drug Administration (FDA), and the National Cancer Institute (NCI), specifically the caBIG® program.

Beginning with the release of BRIDG version 1.0 in June 2007, caBIG® contributed the data models for the Cancer Clinical Trials Object Model (CTOM) and the Patient Study Calendars (PSC). These first models were supplemented in BRIDG version 2.0 by information on adverse events (caAERS), the participant registry project, and models describing Persons/Organizations, part of the caBIG® COPPA project (Correlations, Organizations, Persons and Protocol Abstractions). More information about caBIG®'s involvement with BRIDG can be found here.

Current Solution

[Optional, briefly describe the existing solution and shortcomings.]

Proposed Solutions

Semantic Inheritance Concept Mapping: SIW Support for Complex DataTypes - Solution Chosen

This solution suggests to treat certain data types as associations, and certain data types as simple attributes.

The caDSR curation team will make a determination as to which data type will be treated as an association and which will be treated as an attribute.

A list of valid data types will be published so that model owners know which types they can use.

Functional Requirements

caDSR will only load ISO 21090 Data Types that are relevant to the COPPA Model and the BRIDG 2.1 Model. All other remaining data types will be loaded in caDSR at a later time.

Please see ISO 21090 Data Types spreadsheet (MasterListwithBRIDG.xls - no longer online)

Brief description of non-functional requirement

(Approved or Proposed)


Example, "Although there are no functional changes to the product for this requirement, the team must migrate the existing software to Hibernate 4.1 to be compatible with the caCORE technology stack."

General Support Activities

This section describes in detail all the related activities which must be performed for this release but do not add functionality. These activities are included in the scope and project plan due to level of effort or relative importance to the overall success of delivery of the release.

Out of Scope Items

Items that are out of scope were evaluated as part of the initial scoping activities for this release, and subsequently not included in the final approved scope. These items are also documented in the cumulative backlog of requirements found on the product GForge site. They include out-of-scope functional requirements (enhancements or new features), bug fixes, non-functional requirements, and general support activities.
