A breakdown...

The URI for the term stays constant over time:

        URI:            http://purl.org/dc/elements/1.1/date

The amespace and name are the prefix and suffix of the terms’ URI

        Namespace:      http://purl.org/dc/elements/1.1/
        Name:           date

A human-readable label, definition, and comment – in English

        Label:          Date
        Definition:     A date associated with an event in the life cycle of the
                        resource.
        Comment:        Typically, Date will be associated with the creation or
                        availability of the resource.  Recommended best practice
                        for encoding the date value is defined in a profile of
                        ISO 8601 [W3CDTF] and follows the YYYY-MM-DD format.
