Obsidian
Scientific applications vary widely in data management requirements: types and sizes of objects, rate of production, number of data sources, query and access patterns. A typical approach to this problem generalizes requirements from multiple applications and builds a single, integrated system. An alternate approach is to build an architecture or toolkit of reusable, open source utilities that can be rapidly assembled for specialized data management solutions that scales up to Grid collaborations and scales down to individual lab needs.
Obsidian provides such an architecture and has been successfully used for collaborations in:
- X-ray crystallography
- Photometric studies in astronomy
- Clinical radiation therapy
- Bioinformatics
- Fusion energy simulations
Obsidian can be accessed as a library, a web service that works with science portals, or a CCA component.
