Meta

The XLSForm specification includes several meta question types that capture specific information related to the form or device. Here is a description of each meta question type:

1. start: The start question type marks the beginning of the form and is typically used to capture the start time of data collection. It serves as a reference point for tracking the duration of the data collection process.

2. end: The end question type marks the end of the form and is used to capture the end time of data collection. It helps in calculating the total duration of the data collection process.

3. deviceid: The deviceid question type captures the unique identifier of the device used for data collection. It can be useful for tracking and identifying the specific device associated with a particular set of collected data.
