Copyrighted

Copyright

"Copyrighted" means that the copyright owner is exercising full rights.

Here's a decent article discussing the basics: https://www.wipo.int/copyright/en/

That means you cannot:

• edit the document
• make derivative works
• re-post the document

You may LINK to the document, but that's about it.

Creative Commons Licenses

Creative Commons Licenses are interesting because they leverage Intellectual Property rights in specific ways. Basically, the original copyright owner specifies specific conditions in which their work can be used, which generally follow along several options:

• BY -- you can use the document freely (edit, deratives, repost, charge $$) as long as you include attribution to the original copyright holder
• NC -- you can use the document freely for non-commercial purposes
• SA -- you can use the document freely but any derivative works must share the same exact set of permissions as the original
• ND -- you can use and report the document, but you may not make any changes or produce derivative works

These rights are normally grouped into one of several licenses:

CC-BY: https://creativecommons.org/licenses/by/4.0/

• (tl;dr: you can do anything you want as long as you attribute the original (BY))

CC-BY-NC-ND: https://creativecommons.org/licenses/by-nc-nd/4.0/

• (tl;dr: you can download and repost but cannot change anything (ND) AND must attribute original (BY) AND cannot be used for commercial purposes (NC))

CC-BY-NC-SA: https://creativecommons.org/licenses/by-nc-sa/4.0/

• (tl:dr: you can download and repost and change whatever you want (as long as you include attribution to original) (BY) but any derivative work must follow the same licensing guidelines (SA) AND cannot be used for commercial purposes (NC))
