2.3.12 Metadata

Metadata are custom properties that you can save to your Capture files that allow you to filter your sensor data based on characteristics of the files. Metadata properties are normally attributes about the subject or object you are recording.

Metadata are used to:

1. Differentiate the subset of captures that you want to work with for modeling

2. Perform aggregations for feature generation (i.e., do SQL-like group-by operations)

Examples:

client.project.metadata_values()

client.project.metadata_columns()

class mplabml.datamanager.metadata. Metadata(connection, project)

Base class for a label object
