Jump to navigation Jump to search

This page is to help writing requests for people to share their work under an open license compatible with Appropedia.

Example 1[edit source]


I am a member of the community at Appropedia, a wiki for Sustainability and development. I recently became aware of some excellent work of yours that would be a great fit at Appropedia.

We use the Creative Commons Attribution-Share Alike license, which gives rights to people to reuse and make derivative works, as long as they give attribution (which usually means a link to the original site - in this case, your site) and they share any improvements they make to the content under the same conditions. Therefore, anything we use on Appropedia needs to be shared under those terms. This license is used by many other organisations including Wikipedia and most other wikis so content under this license can be easily shared and copied between these sites. See our CC-BY-SA page for more information.

  • Can you confirm that you own the copyright, or are authorised to act on behalf of the copyright owner for #Name of Document we would like to use#?
  • Will you agree to distribute this work under the Creative Commons Attribution Share Alike license (unported, version 3.0 or later)?

This is prompted by our wanting to use particular works of yours. However, we recommend using free licenses for all your work, and being part of the "green commons" for knowledge on sustainability. Do you have other content which you agree to distribute under this license?

Let me know if you have any questions,


Example 2[edit source]

This is an example that can be used for contacting copyright holders or (for works without explicit copyrights) authors. Minor adjustments may be made, but the key elements regarding requesting permission, mentioning and describing the CC-BY-SA license and directing to the text, and requesting explicit permission for specific content are all required.

Example 2[edit source]

A conversation starter - leaves confirmation of license till later, but gives the links for them to read for themselves:

Hi - I've just been looking at your website. I am with Appropedia, the sustainability wiki, and we all have a lot in common in terms of our interest in ("creating abundance with a small footprint," or something relevant to the specific site). and Sharing knowledge about how to do that.

We would love to be able to share your wisdom on Appropedia. Have you considered using an Open license that would allow us to do that? With attribution of course.

I hope to hear from you.
