Is there any kind of metadata associated with dictionaries? If not, are there reasons to add it and ways to do it, or is that the domain of a DBMS?

In programming languages like Python, dictionaries themselves don’t inherently carry metadata in the way that a database management system (DBMS) might handle metadata. However, you can achieve similar functionalities by incorporating metadata into your dictionary structure or by using nested dictionaries, as such:

my_dict = {
    'data': {
        'key1': 'value1',
        'key2': 'value2'
    },
    'metadata': {
        'created_at': '2024-02-15',
        'created_by': 'user123'
    }
}
