Object property hasTopic has two ranges: "Topic" and "EditorialObject"

[JuergenGrupp]

The two ranges should be combined with an or-statement:

1) EditorialObject hasTopic (Topic or EditorialObject)

[tormodv]

Yes, this is a bug, but there might be more than one. "hasTopic" is a sub-property of hasSubject, but they do not have the same range. We have other properties without range, and the proper class restriction implicitly defines the range.

So a solution can be to remove the hierarchy and the range statement.

Or should we use "min 0" here too?

What about EditorialObject concerning EditorialObject

or isAbout?

[JuergenGrupp]

I think we should use a new property like "isAbout", and not include it in the above mentioned hierarchy of hasSubject.
