Abstract:
Scientists have always recognized the importance of sharing data to maximize research impact and establish new collaborations. However, past efforts to develop public data repositories have fallen short of fulfilling their intended role due to not being able to address users’ needs. Toward enabling researchers to share data and collaborate on data analytics effectively we propose SCICADA, a Secured Cyber-Infrastructure for Collaborations and Advancing Data Accessibility. SCICADA is developed based on the recognition that: (1) Data owners are prohibited by the lack of control over their dataset once it’s openly available through a public repository (e.g., no accountability for attribution, access control, and misuse); and (2) Researchers using data from public repositories are challenged by the lack of information on data provenance, data quality, and support from the primary data collectors. SCICADA is a secured peer-to-peer collaboration and data-sharing platform that comprises an index of simplified data descriptors to enable elastic search and a data-collaboration utility called Globally Federated File System (GFFS, an XSEDE product). Through these services, SCICADA is portable and capable of supporting different modes of data collaborations – well beyond what is possible with public repositories. In this webinar, we describe the effort of integrating SCICADA’s core components (identity management, elastic search, and GFFS). We also discuss key issues such as security, performance, and scalability. If time permits, we may also discuss our strategy for deployment and community building.
