We're starting to use the one site web service to do ad hoc queries on sites in our area. Some of these are large coastal/marine sites and bring back a lot of data.

We want to limit the data coming back by filtering on dataset because generally we're only interested in a limited number of datasets for each search. I want to make this flexible by presenting all datasets in a checkable list so that we can select the ones we want before each search.

My difficulty is that I cannot find a way to retrieve a list of all the datasets (and dataset keys) available on the Gateway to put into this list. There doesn't appear to be a dataset discovery service per se.

I thought that I'd be able to use the dataset list service, but as far as I can see, this service itself forces you to use a filter of either a taxon, a taxon reporting category or dataset. So there doesn't seem to be a way for me to get a complete list back.

Am I right of have I missed something? If I'm right, can anyone think of a workaround?
