I'd like to propose that we add the 'dc.creator' metadata field to the Author Browse index in out-of-the-box DSpace. This would also be more consistent with our Search Index (which indexes 'dc.creator' as an Author already by default).
Currently, in DSpace 1.5.x, the Browse Configuration in dspace.cfg only indexes 'dc.contributor.*' fields as Authors:
webui.browse.index.2 = author:metadata:dc.contributor.*:text
I'd like to suggest we make the very minor change to also index 'dc.creator':
webui.browse.index.2 = author:metadata:dc.contributor.*,dc.creator:text
I can commit this change in preparation for 1.6 assuming others agree that this seems like a reasonable setting for out-of-the-box DSpace.
