Question about records, and identifiers:
Geographic data often comprises many files (tiff with tiff world, in this case).
We have catalog records of these files. The question becomes what are we
describing when I point to a catalog record which lists the various pieces,
rather than the actual image/data.
If I point at a catalog record, would this make the OAI record a service? or is
it still an image? or is it both?
Since the final resource is really an image, I am planning on leaving the type
as "image", with a format of image/tif (even though no image/tif exists in the
official dcmi type vocabulary (
http://www.isi.edu/in-notes/iana/assignments/media-types/media-types )
I've attached a present draft of the sample record.
