Purposes of MDF Files
Measurement Data Format, or MDF for short, is a binary file format used to store measured or recorded data for offline analysis, long-term storage, or post-measurement processing. Although it is utilized in many other application areas, the format for measurement and calibration systems (MC-systems) has come to be considered the de facto standard. Large volumes of measurement data can be efficiently and highly performantly stored using ASAM MDF, a compact binary format. The raw measurement values and associated conversion formulas can be stored in the file format, allowing post-processing tools to correctly interpret and assess the raw data. Descriptive and modifiable additional data can also be stored in MDF files. Flexible extensibility is provided by ASAM MDF through generic XML fragments and a number of new features like events, attachments, and custom signal grouping.
