licenselynx 2.3.0

Deterministically map license strings to its canonical identifier

LicenseLynx for Python

To use LicenseLynx in Python, you can call the map method from the LicenseLynx module to map a license name to its canonical form. The return value is an object with the canonical name and the source of the license.

Installation

To install the library, run following command:

pip install licenselynx 

Usage

from licenselynx.licenselynx import LicenseLynx

# Map the license name
license_object = LicenseLynx.map("licenseName")

print(license_object.id)
print(license_object.src)

# Map the license name with risky mappings enabled
license_object = LicenseLynx.map("licenseName", risky=True)

Organization Licenses

Organizations can register internal/proprietary license identifiers that are kept separate from OSS licenses. To look up an organization license, pass the org parameter:

from licenselynx.licenselynx import LicenseLynx
from licenselynx import Organization

# Map a license name within an organization
license_object = LicenseLynx.map("licenseName", org=Organization.SIEMENS)

The LicenseSource enum is also available for inspecting the source type:

from licenselynx import LicenseSource

Helper methods on the returned license object:

# Check if the license comes from any organization
license_object.is_organization_source()  # returns True if from any org

# Check if the license comes from a specific organization
license_object.is_organization_source_of(Organization.SIEMENS)  # returns True if from Siemens
