As far as I am aware, there is no guidance in TMF assets regarding how to name characteristics. Bear in mind that characteristic names, especially in product (BSS) layer, are likely to be displayable to end customers.
Disregarding for the moment the issue of support for multiple national languages, this would indicate that names should be "friendly", avoiding complex acronyms, including spaces, and initial capitalization, such as Network Role, Notes, etc.
If, however, you devolve all displayable strings, including catalog strings, to a content management system, the characteristic names become more like software elements, and you might want to adopt the conventions for attribute/property names.
Hope it helps
