optional arguments:
  -h, --help            show this help message and exit
  -c CONFIG_FILE, --config-file CONFIG_FILE
                        path to a config file with a noid section
  -v, --validate        validate the given noid [default: False]
  -s SCHEME, --scheme SCHEME
                        the noid scheme [default: 'ark:/']
  -N NAA, --naa NAA     the name assigning authority (NAA) number [default: ]
  -t TEMPLATE, --template TEMPLATE
                        the template by which to generate noids [default: 'zeeddk']
  -n INDEX, --index INDEX
                        a number for which to generate a valid noid [default: random positive integer]
  --verbose             turn on verbose text [default: False]

Validating a noid

Validate a noid using the -v/--validate flag and pass a noid.

noid -v $(noid) # self-validation

API Usage

You can also use this package's API in your code.

import random

from noid import mint, validate, calculate_check_digit, generate_noid

# with default arguments
noid = mint()

# arguments: template, n, scheme, naa
noid = mint(template='zeedeeedk', n=37, scheme='https://', naa='802938')

# validating a noid
validate(noid) # True/False

# calculate the check digit
calculate_check_digit(noid)

# low-level generate a noid from a mask and number; no check digit is appended
noid = generate_noid('eeddeed', random.randint(100, 1000))

Testing

pip install -r requirements.txt
