spdx-licenses

A simple module to determine if a license id is a valid SPDX license and if it is, get the full name and a flag indicating if the license is OSI approved.

Each license entry has the following information:

• name - The full name of the license, e.g. "Academic Free License v3.0"
• id - The abbreviated id you used to acquire the license, e.g. "AFL-3.0"
• OSIApproved - A boolean flag that is true when the license is OSI approved.

An exmaple license follows:

1    "MIT": {
2        "name": "MIT License",
3        "id": "MIT",
4        "OSIApproved": true
5    }

Example usage

1    var spdxLicenses = require('spdx-license');
2    var target = 'LGPL-3.0+';
3    var license = spdxLicenses.spdx(target);
4
5    if (license) {
6        console.log('We are working with the Software Package Data Exchange® '+
7            'list version: ', spdxLicenses.version);
8        console.log('The full name for "LGPL-3.0+" is: '+license.name);
9
10        if (license.OSIApproved)
11            console.log('The license is OSI approved.');
12        else
13            console.log('The license is not OSI approved.');
14    } else {
15        console.error('There is no such license as '+target);
16    }

The above results in the following output:

We are working with the Software Package Data Exchange® list version:  1.19
The full name for "LGPL-3.0+" is: GNU Lesser General Public License v3.0 or later
The license is OSDI approved.
