Extending the data model for data-centric metagenomics analysis using scientific workflows in CAMERA

Community Cyberinfrastructure for Advanced Marine Microbial Ecology Research and Analysis (CAMERA) is an eScience project to enable the microbial ecology community in managing the challenges of metagenomics analysis. CAMERA supports extensive metadata based data acquisition and access, as well as execution of metagenomics experiments through standard and customized scientific workflows. Users can use a wide range of community analysis tools to select and invoke integrated annotation of genomic datasets. Users can also search and sort information based on selected metadata over the underlying semantic database. We present the semantic data model of CAMERA and its integration with scientific workflow execution information. We also describe how this model is used to interlink related workflows, where outputs of previous workflow executions can be used as inputs by subsequent workflow executions. We demonstrate the effectiveness of our model and approach through scenarios built on currently supported CAMERA workflows and analysis. © 2010 IEEE.
