I'm posting there as i haven't found any mailing-list for the geography subgroup. I would like to discuss the use of GML for geographical data in systematics databases. GML is (or will become soon) a standard for geographical data exchange/storage, so it would be really interesting to use it for our own needs. Moreover, it's really designed to be included in other data formats. However it is mostly coordinate-based, while most of our current data are not. We have relationships between locations/areas, such as 'collection x is located in city y, that is located in country z', but rarely latitude and longitude of a them. GML could eventually support strictly hierarchized data, such as points located inside an area, but not overlaping areas realtionships. Has anyone else already examined this issue ? -- Guillaume Rousse <rousse@ccr.jussieu.fr> GPG key http://lis.snv.jussieu.fr/~rousse/gpgkey.html
