spdx-license-urls

Provide license name via spdx-licenses, generated license URLs and additional details.

Main purpose of this module is to centralize efforts for URL template maintaince and anomaly handling.

The additional info on licenses is very sparse for now, so feel free to pull-request better data for your favorite licenses.

API

• licu(spec): Try to find info on the license spec specified as an SPDX string. If found, return that info as a JS object, else return false.
  • Special list attributes: Some keys in the info object are each either false or an array of identifier strings that you might want to lookup further. The lists have not been checked for validity, so be prepared for errors in the follow-up lookups.
    • alertnatives: Alternative licenses. licu() might know about them.
    • exceptions: Special terms and conditions. licu() can ask the spdx-license-exceptions module about them. Some of them grant additional usage permissions with fewer restrictions, e.g. for fonts.
• licu.orThrow(spec): Like licu(spec) but on failure, throw an error instead of returning false.
• licu.spdxVersions: The list versions of lookup tables used.
