Hi there!
Is there any way to have multiple classes assigned to a resource template or multiple properties to a single property field?
I think this is useful for using similar properties that come from vocabularies with different purposes like RDA and schema.org; also making interlinking of structured datasets more flexible.
So, you’re thinking of having the same values be applied to multiple properties automatically?
There’s currently no way to do that, or to assign multiple classes for a resource. Multiple classes for a resource and/or template is probably the more likely of the two in terms of potential features. “Sharing” a value across several properties would be tricky, to say the least (if ever done, it would probably only be possible through the template system, i.e. identifying other “same” properties as part of configuring a property for the template).
