Degree of certainty

[margur78]

In the case of the authorship of a composition one may encounter a composition whose composer can be uncertain, probably, highly plausible, etc. It happens in Tonalities project, but I guess that is a common problem with Tunes and maybe also Facets.

If I am not wrong, currently there is no way to express a "degree of certainty" in PON-MusicMeta or in the Core ontology. Please consider that a "degree of certainty" can potentially be applied also to other metadata, like places, titles, dates, etc.

I wonder if there is the possibility to manage this aspect in a general way, in order to be applied to a large range of metadata.
