John -- See http://www.loc.gov/standards/mods/v3/mods-userguide-elements.html#coordinates ------ <coordinates> "coordinates" contains a statement of coordinates covered by the resource. One or more statements may be supplied. If one is supplied, it is a point (i.e., a single location); if two, it is a line; if more than two, it is a n-sided polygon where n=number of coordinates assigned. No three points should be co-linear, and coordinates should be supplied in polygon-traversal order. ------- We should correct this. "statement of coordinates" was intended to represent a single point (i.e. a single pair - latitude and longitude) and looking closely at it, it doesn't (it seems that it represents a bounding box, i.e. 4-sided polygon). So we need to change the wording, so that: " 'coordinates' contains a statement of coordinates covered by the resource. One or more statements may be supplied." should be replaced by something along these lines: " 'coordinates' contains a pair of coordinate representing a single geographic point. It is repeatable (so one or more points may be specified)." I take it that you want to represent a bounding polygon, arbitrary number of sides (i.e. not limited to a 4-sided polygon)? --Ray ----- Original Message ----- From: "John Banning" <[log in to unmask]> To: <[log in to unmask]> Sent: Wednesday, May 10, 2006 4:37 PM Subject: [MODS] <coordinate> examples Hi all, I was curious if anyone could provide examples of how geographic coordinates are being represented in MODS. I am specifically interested in representing bounding coordinates for maps. I read in the user guide that the information contained in this element is "equivalent to MARC 21 fields 034 and 255" but wanted to know specifically if decimal degree (34.558889°, 16.253889°) or degree/minute/second (34° 33' 32.00", 16° 15' 14.00") the preferred geographic representation? Thanks in advance, John Banning
