Support for rdflists in authors and contributors

Is your feature request related to a problem? Please describe.
In order to preserve author/contributor order, one may use an rdf list. But this is not properly recognized by Widoco at the moment.
Example: https://github.com/glosis-ld/glosis/blob/master/glosis_unit.ttl

Describe the solution you'd like
The list should be properly recognized, and the order, preserved.
