I can use this function with the view below, which lists Australian Faunal Directory publications by UUID ("value"), indexed by DOI ("key").
I can get the tab-delimited dump from http://localhost:5984/afd/_design/publication/_list/tsv/doi. Note that instead of, say,
/afd/_design/publication/_view/doito get the view, we use
/afd/_design/publication/_list/tsv/doito get the tab-delimited dump.
I've created files listing DOIs and BioStor ids for publications in the Australian Faunal Directory. I'll play with lists a bit more, specially as I would like to extract the mapping from the Australian Faunal Directory on CouchDB project and add it to the iTaxon project.
