metadata layer

The metadata layer has no datasets, and instead uses the following attributes to further describe the MIR data file:

generator_name

Name of the program that created the file, stored as a Unicode string.

For example: foobar

generator_version

Version of the program that created the file, stored as a Unicode string.

For example: 1.0.3

mir_version

Version of MIR specification used when creating the file, stored as a Unicode string.

For example: 1.12.3

created_at

Date and time at which the file was created, stored as a Unicode string in ISO 8601 format.

For example: 2017-08-15T13:51:02+02:00
