Flexible Creation and Adaptive Execution of Scientific Workflows in Cloud and Grid Environments by Using Web 2.0-Based Electronic Lab Notebook Metaphor

A metaphor of Electronic Lab Notebook (ELN) can be leveraged not only to make the process of creation and editing of scientific workflows easier, but to execute, monitor, and troubleshoot workflows. By using ELN as a metaphor for Scientific Workflow Management System (SWFMS), scientific users can have the familiar user interface it offers with the benefits of SWFMS, such as the ability to automate recording provenance of scientific experiments and to facilitate reproducing of scientific results. Furthermore, Web 2.0 can enhance ELN to make it easier to collaborate and share scientific content by using emerging Web standards. Cloud and Grid environments require that workflows be fault-tolerant and can adapt to changes. ELN, as an underlying storage model for SFWMS, allows necessary flexibility in adapting running workflows both automatically and by users editing ELN to change their workflows.
