These keys have all changed (there is a family of them), but I shall add descriptions to the translation files.
Where "rank" is one of the variables, they resolve in formats similar to this: "Species recognized by Integrated Taxonomic Information System:" or "Integrated Taxonomic Information System as a Taxon". In the latter case, this entry would be seen as a paragraph under a header named "Recognized by". These can get more complex, as occasionally the values are created with Rails' #to_sentence method. Thus, you can end up with "The Integrated Taxonomic Information System and T Orrell (custodian) in Catalogue of Life as a Taxon", where the "and" was inserted between two values for the "recognized_by" variable. These do not need to read with prefect grammar, as they are meant to be citations and not flowing speech.
Hope that helps.
