eXtensible Data Model and Format [1] XDMF (eXtensible Data Model and Format) provides a standard way to access data produced by HPC codes. [1] Data format refers to the raw data to be manipulated, the description of the data is separate from the values themselves. It distinguishes the metadata ( Light data) and the values themselves ( Heavy ...
In communications and computing, a machine-readable medium (or computer-readable medium) is a medium capable of storing data in a format easily readable by a digital computer or a sensor. It contrasts with human-readable medium and data . The result is called machine-readable data or computer-readable data, and the data itself can be described ...
Apache Parquet is a free and open-source column-oriented data storage format in the Apache Hadoop ecosystem. It is similar to RCFile and ORC, the other columnar-storage file formats in Hadoop, and is compatible with most of the data processing frameworks around Hadoop. It provides efficient data compression and encoding schemes with enhanced ...
Hierarchical Data Format (HDF) is a set of file formats (HDF4, HDF5) designed to store and organize large amounts of data.Originally developed at the U.S. National Center for Supercomputing Applications, it is supported by The HDF Group, a non-profit corporation whose mission is to ensure continued development of HDF5 technologies and the continued accessibility of data stored in HDF.
