ZooBank continues to use the old Identifier cross-link system within GNUB. We need to update the Zoobank website and associated GNUB data services to use BioGUID.org services for identifier cross-linking.
Need to create an "Advanced" search system tat includes other filter parameters (Object Class, Identifier Domain, Dereference Service, Identifier Class, etc.).
Need to decide how to assign values included in the occurrenceID field of the GBIF dataset to determine how best to index them (particularly in terms of assigning them to Identifier Domains).
