Always one to share my choice of licence is attributable, non-commercial, share alike. Whilst I'm totally happy for anyone to use and modify my work I want credit and I don't want anyone else making money from it. Same license as Wikipedia.
Also - mostly to remind myself here are Wiley's 5R's - which pretty much fit my ideal of sharing.
David Wiley (2007) has been one of the key thinkers and drivers in open content, and he proposes the 5Rs of Reuse[Tip: hold ⌘ and click a link to open it in a new tab. (Hide tip)]:
- Retain – the right to make, own, and control copies of the content (e.g., download, duplicate, store, and manage)
- Reuse – the right to use the content in a wide range of ways (e.g., in a class, in a study group, on a website, in a video)
- Revise – the right to adapt, adjust, modify, or alter the content itself (e.g., translate the content into another language)
- Remix – the right to combine the original or revised content with other open content to create something new (e.g., incorporate the content into a mashup)
- Redistribute – the right to share copies of the original content, your revisions, or your remixes with others (e.g., give a copy of the content to a friend)
