Mapping licenses

The ISO19139 field that is used to express the license in CKAN is the one displayed in GeoNetwork as “Resource constraint” (Italian labels: “Vincoli sulla risorsa”/”Limitazione d’uso”).

This field is a free text, that needs to have one of these values to be properly parsed by CKAN:

String	Open License
odc-pddl	LicenseOpenDataCommonsPDDL http://opendatacommons.org/licenses/pddl/
odc-odbl	LicenseOpenDataCommonsOpenDatabase http://opendatacommons.org/licenses/odbl/
odc-by	LicenseOpenDataAttribution http://opendatacommons.org/licenses/by/
cc-zero	LicenseCreativeCommonsZero http://creativecommons.org/publicdomain/zero/1.0/
cc-by	LicenseCreativeCommonsAttribution http://creativecommons.org/licenses/by/3.0/
cc-by-sa	LicenseCreativeCommonsAttributionShareAlike http://creativecommons.org/licenses/by-sa/3.0/
gfdl	LicenseGNUFreeDocument http://www.gnu.org/copyleft/fdl.html
other-open	LicenseOtherOpen
other-pd	LicenseOtherPublicDomain
other-at	LicenseOtherAttribution
uk-ogl	LicenseOpenGovernment

These are the values for the recognised non-open licenses:

String	Non-open License
cc-nc	LicenseCreativeCommonsNonCommercial http://creativecommons.org/licenses/by-nc/2.5/
other-nc	LicenseOtherNonCommercial
other-closed	LicenseOtherClosed

Values different from these ones will be handled as non-recognized closed licenses.
