The OpenEDI Specification defines a standard, language-agnostic, and format-agnostic interface to all EDI and HL7 messaging standards, allowing them to be used with HTTP APIs by both humans and computers.
I'm evaluating your format for use in our company, and I'm wondering if there's a potential license problem. Section 6 of the apache licence specifically states that you do not allow use of trademarks, but at the same time, your format specifically uses your trademark in all the object keys, specifically x-edination-.
It would probably be useful for you to explicitly allow the use of the edination trademark in code derived from this specification in your license grant or README.
Alternatively, replacing x-edination with x-openedi in a new version of the standard would also solve this problem (if openedi isn't trademarked)
