     41We 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.
     42 * !OpenStreetMap IDs can change over time if records are deleted/recreated
     43  * They can [http://wiki.openstreetmap.org/wiki/Humanitarian_OSM_Tags/Humanitarian_Data_Model#ID hold additional uid/uuid fields] though
     44 * Geonames data isn't free enough for OSM: http://wiki.openstreetmap.org/wiki/Geonames
     45  * Geonet can be: http://wiki.openstreetmap.org/wiki/GEOnet_Names_Server
     46 * Yahoo WoE data is in the public domain:
     47  * XML: http://code.flickr.com/blog/2009/05/21/flickr-shapefiles-public-dataset-10/
     48  * Tab: http://developer.yahoo.com/geo/geoplanet/data/
     49 * Ushahidi doesn't have a common set of IDs across instances
     50  * No space for a UUID either?
     51 * Longer-term we need a common central repository of UUIDs that is held for the common good.
     52  * Propose that Sahana start this off & then give up ownership/branding later:
     53  * Sahana can use UUIDs of format: http://geo.sahanafoundation.org/<ID>
     54  * These are associated with an OSM ID & Geonames ID for cross-correlation
     55  * The Source ID field shows the source, so that OSM export can filter out sources like Geonames
     56  * IDs from Ushahidi instances can be appended to the comments field in Sahana
