Each license begins as a traditional legal tool, in the kind of language and text formats that most lawyers know and love. We call this the Legal Code layer of each license. But since most creators, educators, and scientists are not in fact lawyers, we also make the licenses available in a format that normal people can read — the Commons Deed (also known as the “human readable” version of the license).
The Commons Deed is a handy reference for licensors and licensees, summarizing and expressing some of the most important terms and conditions. Pendientedemigracion.ucm.es/info/multidoc/multidoc/revista/num10/paginas/pdfs/Codina.pdf.
