Hi Kim & Erik,

I've dumped the GBIF backbone from our postgres 9.3 server and placed it here (427MB):

The tables should be fairly straight forward with taxa being in "name_usage" and names in "name".
A simple join to get the core properties for a taxon would be this sql:

	select u.id, parent_fk,n.scientific_name, rank, status, p.citation as publlishedIn from name_usage u join name n on name_fk=n.id left join citation p on name_published_in_fk=p.id order by rank limit 100;

The backbone is the current live one with the higher classification coming from the Catalog of Life.
Quick facts:

  taxa incl synonyms:  4.416.347
  synonyms:  1.143.026
  names: 4.410.899
  accepted taxa by rank:
	PHYLUM: 111
	CLASS: 272
	ORDER: 1183
	FAMILY: 20760
	GENUS: 390790
	SPECIES: 2497114
	VARIETY: 149011
	FORM: 40473
