19.1.1.3 HDF5

XML is not very efficient at handling large volumes of numerical or array data, so for this purpose Energistics uses the Hierarchical Data Format, version 5 (HDF5), which is a data model, a set of open file formats, and libraries designed to store and organize large amounts of numerical/array data for improved speed and efficiency of data processing.

DAS uses HDF5 to store both raw and processed measurement data. HDF5 is also part of the CTA, and its general use in Energistics is described in the CTA Overview Guide.

For more information about how to use HDF5 with DAS, see 19.5 Defining the DAS Acquisition Data (Raw and Processed Data) .
