Based on similar experiences in other Schema.org extension areas, when it has become complex/difficult to gain consensus on a particular point, especially with an initial proposal: I suggest that we agree on a property name for this (these) concepts and create it with a range of Text and a suitable, not too specific, description. After some use in the real world, we can then review that usage and come up with enhanced propert(ies) definition, range, etc. as part of a further following proposal. At this current stage translating the forgoing discussions in this email trail into a concise description, that will be understandable to the Schema,org community that will receive, and hopefully accept, our proposals seems a challenge too far for this initial release. ~Richard Richard Wallis Founder, Data Liberate http://dataliberate.com Linkedin: http://www.linkedin.com/in/richardwallis Twitter: @rjw On 16 February 2018 at 17:39, Nate Otto <nate@ottonomy.net> wrote: > Thanks for digging in to get more precise on level here. > > I like how the SCQF reasons about levels of accomplishment.
