Topics • Use Case • TRIAD • openMDR • TRIAD – openMDR Workflow • Questions
Use Case • A clinical researcher is conducting an outcomes study in which they want to utilize data collected during the course of standard clinical care, as well as bio-specimen data from the Tissue Bank. • For patients that have consented to have their tissue specimen stored in the Tissue Bank with specific sexGenotype, ethnicity and gender - The researcher is interested in knowing Pre-Operating Room Diagnosis and Procedure, as well as Post-Operating Room Diagnosis and Procedure. • The researcher would like to be able integrate and analyze all of this information as a single data set.

The Translational Research Informatics and Data Management Grid (TRIAD) TRI D
TRIAD Introduction • TRIAD = CTSA + caGrid • Data Service Wizards • Federated and Localized Metadata Management • caBIG - Cancer Biomedical Informatics Grid • Grid - “Controlled and coordinated resource sharing and problem solving in dynamic, scalable virtual organizations.” • caGrid - Provides the software infrastructure that underlies the tools and applications of caBIG TRIAD middleware
TRIAD Design • TRIAD is an instance of caGrid that leverages existing, core components: • Service oriented architecture utilizing Axis, Globus, and caGrid extensions. • Data model management via the Global Model Exchange. • Customizable security infrastructure leveraging GAARDS. • Graphical strongly typed grid service creation using Introduce. • Extendable and customizable web service infrastructure. • TRIAD extends caGrid: • Additional options for data service creation, security policy, metadata management, etc. • Federated and/or local metadata management utilized for semantically annotated grid service creation • “Out of the box” data services for popular tools such as I2B2 and RedCAP • Integration with commercial and open-source CTMS platforms TRI D
Compatibility and Interoperability • caBIG® provides standards-based compatibility guidelines for creating software systems that are syntactically and semantically interoperable.

Enhanced Data Services • Data service generation wizards for common data centric applications Class Model & Assertions CDEs & Semantics
TRIAD Development Process Create an Information Model using a modeling tool Perform Semantic Integration using the EA Plugin Transform the Model into Metadata using the Domain Model Gen. Generate Code and Interfaces using the caCORE SDK Code Generator Generate a Grid Service using Introduce Information Models Vocabularies CDEs APIs Grid • caCORE is a robust set of tools and resources to support the development of caBIG®-compatible systems • NCI offers comprehensive training for caCORE tools Reference: Dr. Robert Freimuth, Vocabulary Knowledge Center Director

OpenMDR-based • Federated WorkFlow openMDR - TRIAD based domain modeling and annotation workflow
openMDR:mdrCORE • Metadata Registry - Capable of storing, versioning, and maintaining semantic and representational metadata. • Utilizing/enhancing the UK cancergridcgMDR ISO11179 database. • Built on eXist database. • Metadata is annotated with conceptual information from a local or remote lexEVSsystem(s). • Web based front-end for creating and curating semantic metadata.
openMDR:mdrQuery • API and Grid Service for querying across many disparate semantic metadata repositories • caGrid grid service - capable of talking to caDSR and many openMDR systems enabling federated query of common data elements. • Enhances and wraps the cgMDRmdrConnector in order to parse the received information into a common format. • caGrid service enables it to be deployed in any local or production grid environment and can be configured and modified to talk to many semantic metadata systems.
openMDR:mdrEAPlugin • Semantic Annotation Tool • Enables semantic annotation of federated semantics • Utilizes MDRQuery service for locating and utilizing CDE’s from multiple semantic metadata sources • Options for Search Filters • Enables Search within “Context” • Tags are created that identify CDE via local unique id • No need to leave the EA environment
openMDR:mdrDomainModelGenerator • Process an MDR Plugin annotated model and create service metadata which will enable the service to be a semantically annotated grid service and easily discovered • The metadata can be used to generate a data service using the Introduce Data Service Wizard.

OpenMDR Service Creation Phases CDE curation in Local instance of openMDR - using concepts from Local or Remote (NCI) LexEVSinstance Create an information model - create logical model, data model and Map Object Model to Data Model in Enterprise Architect (EA) Annotate logical model with CDE's in EA - using openMDR EA plugin. Export annotated XMI Create domain model file (XML file) with grid service metadata Generate a system using caCORE SDK 4.X by supplying your UML model as input Create Grid Service - Use Introduce grid Service Authoring Toolkit
