AbstractSpanRole needs TEXTCLASS attribute #57

Closed kosloot closed 5 years ago

kosloot commented 5 years ago

"hd" and "Dependent" nodes are AbstractSpanRole nodes and may NOT have TEXTCLASS. But they contain WordRefs which are textclass dependent. Just like entities, which are AbstractSpanAnnotation and MAY have TEXTCLASS

I think this is unbalanced, probably an oversight.

FWIW: Do we need this Role vs. Annotation distinction?

proycon commented 5 years ago

I think they should probably inherit their textclass from the parent span annotation, as I don't really see a use case for different textclasses within a single span annotation element.

I solved this (more elegant I think) in libfolia for 2.0. closing this
