== GIS Import/Export ==

This page hosts the detailed specification for the [https://blueprints.launchpad.net/sahana3/+spec/gis-import-export Blueprint for the GIS Import/Export].

We need to be able to Import & Export these XML formats to/from the Database:
 * GeoRSS (URL fetch/publish)
 * GPX (File upload/download)
 * GML (? Low priority, not used much in real world)
 * KML (File upload/download & URL fetch/publish)
 * OSM (File upload/download)

This is probably best-done using an XSD parser:
 * [http://georss.org GeoRSS]
  * http://georss.org/xml/1.1/georss.xsd
  * http://georss.org/xml/1.1/gmlgeorss.xsd
 * GPX
  * http://www.topografix.com/gpx/1/1/gpx.xsd
 * GML
  * http://schemas.opengis.net/gml/3.2.1/
 * KML
  * http://schemas.opengis.net/kml/2.2.0/ogckml22.xsd
 * OSM
  * http://dev.openstreetmap.org/~kleptog/osm-0.5.dtd

This claims to be the fastest validating XML parser for Python:

This is another option for Import (via Python structures):
