r

• Import scientific data from various sources through one easy Python API.
• Use iterator patterns for each data source (configurable data generators + functions to get next data chunk).
• Skip parser programming and file format handling.
• Enjoy a common namespace for all data and unleash the power of data fusion.
• Handle data distribution in different modes: (1) local download, (2) caching of accessed data, or (3) online stream access
• Easily pull data on cloud servers through Python scripts and facilitate large-scale parallel processing.
• Build on an extensible plattform: Adding access to a new data source only requires addition of its "DataFetcher.py".
• Open source (MIT License)
