Format condition is wrong and could be improved
[edit]The format condition seems wrong and should be corrected... Should be fixed now (the regexp is assumed to be from start to end and therefore a .* was needed). --Zuphilip (talk) 08:40, 29 August 2017 (UTC)
We could also restrict further: After urn:nbn:
a country code (ISO 3166) has to come and then a separater which is either colon :
or dash -
. The resolving page supports the country codes DE, CH, AT, CZ, FI, HU, IT, NL, NO, SE which seems a good start for the regexp, i.e. something like
urn:nbn:(de|ch|at|cz|fi|hu|it|nl|no|se)[:\-].*
(This is not yet tested). Should we do this? --Zuphilip (talk) 08:54, 29 August 2017 (UTC)
