You err with the last sentence (which indicates that consistent
naming *is* important):

  "CatalogBrain.getPath" is mapped to "ZCatalog.getpath"
  which is mapped to "Catalog.paths".

  And the comment in "Catalog" says 
  
	# self.uids is a mapping of the
        # object unique identifier to the rid, and self.paths is a
        # mapping of the rid to the unique identifier

  The code confirms this comment:

            self.uids[uid] = index
            self.paths[index] = uid
        

Thus, "getPath" *DOES* return the uid and not the path.
