     40== Proposal (nursix): URNs instead of UUIDs ==
     41
     42In the near future, Eden should move from UUIDs to [http://tools.ietf.org/html/rfc2141 URN]s in order to enhance interoperability in multi-application scenarios like Haiti or Pakistan.
     43
     44From experience we know that data exchange in the field can involve a variety of applications other than Eden, each implementing their own identifier schemes - and furthermore data sets which instead of application-specific IDs use officially assigned identifiers (e.g. PAHO IDs for health facilities in Haiti). Implementation of URNs will add support for both multiple different identifier schemes, as well as cross-application common namespaces and ID schemas (as favorable e.g. for geolocations or personal data).
     45
     46In practise, that means:
     47
     48  - there should be a common namespace for sahana applications, at best "sahana"
     49  - uuid="eden.sahanafoundation.org/XXXX-YYYY" would become something like uuid="urn:sahana:eden.sahanafoundation.org/XXXX-YYYY"
     50  - Eden can support other namespaces, by making the namespace a configurable attribute of the "uuidstamp" reusable field
     51
     52
    4053== Mapping ==
    4154We 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.
