The Noun Project holds over 1 million openly licensed icons, however the options for mass importing them are very limited (terms of use for API).
A solution would be to create a tool that helps people upload to Commons icons previously downloaded from The Noun Project. The tool should allow to upload one or many icons as needed whilst making sure the upload adds relevant information to the file on Commons. See [[ https://commons.wikimedia.org/wiki/File:Reindeer_(145926)_-_The_Noun_Project.svg | an example of information added here with this file ]] imported [[ https://commons.wikimedia.org/wiki/Commons_talk:Batch_uploading/TheNounProject | through a bot ]].
Also, CC BY-SA icons have the credit within the file written under the icon. This should be removed as the template added information adding to the icon during upload already includes credit: name, author, link, etc.
**Hint:**
- On The Noun Project icon page url follow a certain patter. Eg: `https://thenounproject.com/icon/145926` with the digit part of the url being the unique ID of the icon. The url contains description such as author name, author url, license, etc.
- When downloaded from The Noun Project, icons in SVG format or PNG have file names with the following a certain pattern. Eg: `noun_145926.svg`
