From the creators:
> The purpose of this project is to create a free, open simple dictionary for students to use. The words in the dictionary will reviewed for quality and appropriateness and ultimately “frozen” for export into a variety of formats, including text, PDF, ebooks, wikis, web, etc., for use on a variety of platforms.
> The site also includes a build-your-own-glossary tool that allows users to construct glossaries for their own books, units, courses, or web sites and export them to text, html, rtf, pdf, or wikitext.
> This is a mass collaboration project, and we hope that you will stop by and add a definition or two.
From [FAQ](http://dictionary.k12opened.com/index.php?p=faqs) page:
> The dictionary is public domain. Anyone may use it for whatever they like.
