Description
"The Open Data Commons project was initially funded by Talis, an innovative technology company with expertise in managing semantically rich metadata and in delivering software and services for information management.
The Open Data Commons licenses themselves came out of the Talis Community Licence, their original open data licence, and draws heavily from the work of others in the open source, free software, and open content community. We owe the many contributors to these licences and concepts a debt of gratitude. The initial draft of the Open Data Commons was created by Jordan Hatcher of opencontentlawyer.com, and by Dr. Charlotte Waelde of the AHRC Research Centre for Studies in Intellectual Property and Technology Law at the University of Edinburgh School of Law.
The first set of licences that were developed by the Open Data Commons team, supported by Talis, are available over at opencontentlawyer.com on this page." (http://www.opendatacommons.org/about/)
