Configuration

The set of dictionary keys holding license_select configuration for values are as follows:

The transform can be configured with the following key/value pairs from the configuration dictionary.

# Sample params dictionary passed to the transform

{ 
"license_select_params" : {
        "license_column_name": "license",
        "deny_licenses": False,
        "licenses": [ 'MIT', 'Apache'],
        "allow_no_license": False,
    }
}

license_column_name - The name of the column with licenses.

deny_licenses - A boolean value, True for denied licesnes, False for approved licenses.

licenses - A list of licenses used as approve/deny list.

allow_no_license - A boolean value, used to retain the values with no license in the column license_column_name

Usage

The following command line arguments are available.

--lc_license_column_name - set the name of the column holds license to process

--lc_allow_no_license - allow entries with no associated license (default: false)

--lc_licenses_file - S3 or local path to allowed/denied licenses JSON file

--lc_deny_licenses - allow all licences except those in licenses_file (default: false)

The optional lc_license_column_name parameter is used to specify the column name in the input dataset that contains the license information. The default column name is license.
The optional lc_allow_no_license option allows any records without a license to be accepted by the filter. If this option is not set, records without a license are rejected.
The required lc_licenses_file options allows a list of licenses to be specified. An S3 or local file path should be supplied (including bucket name, for example: bucket-name/path/to/licenses.json) with the file contents being a JSON list of strings. For example:

[ 'Apache-2.0', 'MIT' ]
The optional lc_deny_licenses flag is used when lc_licenses_file specifies the licenses that will be rejected, with all other licenses being accepted. These parameters do not affect handling of records with no license information, which is dictated by the allow_no_license option.
