The above pull request fixed based_near for to_resource. However, the attempt to migrate from a valkyrie resource back to a fedora object and save in Fedora did not work.

Based_near in Fedora should be saved as a location object, so the migration from a valkyrie resource should handle this behavior (if anyone actually ever needs to do this).
