I am new to the GBIF web services but have had some experience using the web services exposed by ITIS, WoRMS and the Atlas of Living Australia. I have a number of questions that this mailing list may be able to assist with.  I will send each question in a separate email to make it easier to follow threads in case that becomes important.  If appropriate, please just respond by directing me to the relevant web-services documentation (to date I have been working from http://www.gbif.org/developer/species and http://www.gbif.org/developer/occurrence).

My first question is how to request all available taxonomic classification data for a taxon using GBIF web services?

For example, from Atlas of Living Australia web services, a request for that information for the species Ecsenius bicolor yields:

kingdom: Animalia
phylum: Chordata
subphylum: Vertebrata
class: Actinopterygii
superorder: Acanthopterygii
order: Perciformes
suborder: Blennioidei
family: Blenniidae
genus: Ecsenius
species: Ecsenius bicolor

From ITIS, I get the somewhat more detailed:

kingdom:Animalia
subkingdom:Bilateria
infrakingdom:Deuterostomia
phylum:Chordata
subphylum:Vertebrata
infraphylum:Gnathostomata
superclass:Osteichthyes
class:Actinopterygii
subclass:Neopterygii
infraclass:Teleostei
superorder:Acanthopterygii
order:Perciformes
suborder:Blennioidei
family:Blenniidae
genus:Ecsenius
species:Ecsenius bicolor

I can currently get the kingdom, phylum, class, order, family, genus and species from GBIF but I cannot get ranks like subphylum and superorder etc.

I have found an enumeration of taxonomic ranks within GBIF suggesting that such ranks are supported:  
http://gbif.github.io/gbif-api/apidocs/org/gbif/api/vocabulary/Rank.html

However, it is not clear to me how to access this information using the GBIF web services.
 
Any pointers in the right direction would be very helpful.

Many thanks
