The Openness Index
The term open has become popularly used to describe a variety of objects (software and technology, educational resources, education, etc.). Ambiguity exists in the meaning of open, for example open education where anyone can enroll with the only requirement a fee, or open education that is available to anyone, and without a cost. In addition to the ambiguity of open (what it enables), there is also ambiguity with how organizations might operate to allow openness.
The Openness Index attempts to define open attributes and a means to assess the type of openness within the community of practice responsible for the design, development, and distribution of the open artifact.
Importantly, the Openness Index is not designed to assess the "openness" of an artifact (object, software, OER, etc.) claimed to be open–there are plenty of licenses which can be used to assess the openness of an object–rather, the model assess the openness of the organization/community that creates and manages artifact.
