Integrating distributed data grid, ontology and Web-based workflow technologies into geospatial cyberinfrastructure: system design and case study
نویسنده
چکیده
Geospatial research increasingly relies on shared geospatial data, interconnected models and successively refined analysis which requires not only more powerful but also more accessible cyberinfrastructure systems for support. In this study, we propose to integrate data grid, ontology and Web-based workflow technologies to build more accessible cyberinfrastructure systems for geospatial computing by providing essential functionality such as Web-based workflow composition and execution, semantically enhanced data searching and workflow validation, seamless integration of data search and workflow composition and automatic data and workflow provenance. A prototype system is developed to demonstrate the feasibility of the proposed approach and key features are illustrated using an ecological case study.
