    55== Import Data ==

     7=== UUIDs ===
     8We need an agreed set of [http://eden.sahanafoundation.org/wiki/UUID UUID]s for GIS Data so that we can share data more easily across systems.
     9 * !OpenStreetMap IDs can change over time if records are deleted/recreated
     10  * They can [http://wiki.openstreetmap.org/wiki/Humanitarian_OSM_Tags/Humanitarian_Data_Model#ID hold additional uid/uuid fields] though
     11 * Geonames data isn't free enough for OSM: http://wiki.openstreetmap.org/wiki/Geonames
     12 * Ushahidi doesn't have a common set of IDs across instances
     13  * No space for a UUID either?
     14 * Longer-term we need a common central repository of UUIDs that is held for the common good.
     15  * Propose that Sahana start this off & then give up ownership/branding later:
     16  * Sahana can use UUIDs of format: http://geo.sahanafoundation.org/<ID>
     17  * These are asscoaietd with an OSM ID for cross-correlation
     18  * IDs from Ushahidi instances can be appended to the comments field in Sahana
