VTechWorks, http://vtechworks.lib.vt.edu/, uses DSpace 5.3, XMLUI, and has ORCID/authority control enabled. As described in VTechWorks issue #116, https://github.com/VTUL/vtechworks/issues/116, a collection, all with the same value for dc.contributor.author, has two values for the author facet. Both have the same authority value but one is labeled with the authority ID, the other is labeled with the actual author name. The facets have the same authority ID but have different confidence levels. Also the number of items in one of the groups is incorrect.
How can we fix this so there is only one facet and if necessary, all the items in it have the same confidence value?
Also, it would be really great if the confidence value, etc. could be documented more completely in the DSpace Wiki.
