What is important here is that the key names of the above array match the key names of the resource type arrays in STYLEMAP. This is how the data from your particular database is mapped to a format that OSBib understands and this is why you must edit the key names of the resource type array in STYLEMAP. The one exception to this is the handling of creator elements (author, editor, composer, inventor etc.) which OSBib expects to be listed as 'creator1', 'creator2', 'creator3', 'creator4' and 'creator5' where 'creator1' is always the primary creator (usually the author). Do not edit these key names.
