 == Motivation

-FRC robots generate a lot of real-time data of various data types (most typically numeric values, but also strings and more complex data such as camera images). While there is good support in the WPILib software ecosystem for real-time display of this data on dashboards (via NetworkTables), there is no current standard for logging of timestamped data values for offline analysis. In the absence of a standard, teams have developed various ad-hoc solutions, including CSV files.
+FIRST robots generate a lot of real-time data of various data types (most typically numeric values, but also strings and more complex data such as camera images). While there is good support in the WPILib software ecosystem for real-time display of this data on dashboards (via NetworkTables), there is no current standard for logging of timestamped data values for offline analysis. In the absence of a standard, teams have developed various ad-hoc solutions, including CSV files.

 Similar to how the NetworkTables standard protocol enabled ecosystem development of multiple dashboards, it is expected that a standard format for data logging, in combination with built-in library support for easy on-robot logging of robot data, will facilitate ecosystem development of offline data analysis tools.

-Standard logging facilities currently available (e.g. in Java) are generally designed for string messages, not for binary data. As a binary format, this will be faster with less overhead for the typical data (e.g. numbers) coming from a robot in real time (at least dozens, if not hundreds, of data points every ~20 ms). String formatting is significantly more expensive than just copying the binary number, and is more difficult to read back into analysis tools. Latency of the actual logging to the main program is also critical in the FRC application. WPILib also needs a common logging format and implementation across both C++ and Java.

    The WPI Robotics library (WPILibJ) is a set of Java classes that interfaces
