Hi Vlad,Btw: which fields do you use for pictures shot in Galapagos Islands, Frank?
brilliant question
The Galapagos are, politically/administratively, a province ("provincia") of Ecuador divided in three counties ("parroquias").
Geographically the Getty Thesaurus (generally a very widely accepted standard of geographic place names) refers to the archipelago as "island group". That is unfortunate, because a publication by Snell et al. (1995) suggested to group the more than 100 island into several biogeographically and geologically island groups. Thus, for example the central island of Santa Cruz has several close satellite islands, islets and rocks, together Snell et al. (1995) treat thos as one of several main island groups - instead of calling the entire archipelago an island group in the sense of Getty's.
The National Park and the Research station generally follow Snell et al. (1995). So the labels that I am using to tag the photos use the political hierarchy mapped to the relevant IPTC fields, but below that the geo-labels follow Snell et al. (1995) - there are no fields available in IPTC, but the DarwinCore has some suitable fields - like island group and island, to which those labels are mapped.
Cheers,
Frank
