openMDR Release 1.0

Friday February 12, 2010 – The openMDR team is pleased to announce the release of OpenMDR version 1.0. OpenMDR is a suite of software that provides caGrid-compatible semantic metadata management capabilities. The suite includes four different components: 1) MDR Core, 2) MDR Query, 3) MDR Plugin, and 4) MDR Domain Model Generator.

MDR Core - an ISO11179-compliant Metadata registry that stores semantic metadata for a domain or institution. MDR Core is extended from UK cancergrid's cgMDR project (http://cancergrid.org). MDR Core is capable of storing, versioning and maintaining semantic metadata in the form of Common Data Elements (CDEs). Core provides a web frontend for users to create, edit, deploy and re-use CDEs for new UML model development.

MDR Query - An API and Grid Service that supports federated query and retrieval of semantic metadata from repositories across the Grid, including MDR Core and caBIG caDSR.

MDR Plugin - an Enterprise Architect plug-in that allows a modeler to search for relevant semantic metadata using the MDR Query Grid Service. The modeler then annotates the UML model with the chosen CDEs.

MDR Domain Model Generator - a tool used by a caGrid service developer to generate a caGrid domain model from an annotated UML model. This component provides caGrid compatibility by generating a caGrid domain model, an artifact that is required to create a semantically-annotated caGrid Data Service.

In summary, MDR Core is a semantic repository. MDR Query is a grid service used to search multiple semantic repositories (including MDR Core). UML modelers use MDR Plugin to search for semantic concepts from within Enterprise Architect. caGrid Service Developers use the MDR Domain Model Generator to create caGrid data services.
