 ## Generally
 
-Data and content created by government employees within the scope of their employment are not subject to domestic copyright protection under 17 U.S.C. § 105. When purchasing data or content from third-party vendors, however care must be taken to ensure the information is not hindered by a restrictive, non-open license. In general, such licenses should comply with [the open knowledge definition](http://opendefinition.org/okd/) of an open license. Several examples of common open licenses are listed below:
+The open data memorandum, [M-13-13](/policy-memo/), states that federal government data must be open. The "[reusable](/principles/)" principle states that data is open if, at a minimum, it is available under an [open license](/licenses/).

+Data and content created by government employees within the scope of their employment are not subject to domestic copyright protection according to 17 U.S.C. § 105. These works cannot be openly licensed because they are already in the public domain, at least domestically. International copyright may still apply.
+
+When acquiring data or content from third-parties, however, care must be taken to ensure use of the work by the public is possible and not restricted by a non-open copyright license. While an [open license](/licenses/), as defined by [M-13-13](/policy-memo/), is now a minimum requirement, agencies should strongly consider making this data "license-free," i.e. in the public domain, along with the works created by the agency itself.
+
+A worldwide public domain dedication such as [CC0](http://creativecommons.org/publicdomain/zero/1.0/) is recommended by a coalition of non-governmental organizations in this [guidance on making government data license-free](http://theunitedstates.io/licensing/), which includes best practices language, real world government examples, and rationale.
+
+When using a license instead, in general such licenses should comply with [the Open Knowledge definition](http://opendefinition.org/okd/) of an open license.
+
+Several examples of common public domain dedications and open licenses are listed below:
