According to http://www.openarchives.org/OAI/2.0/guidelines-oai-identifier.htm, OAI-PMH identifier must follow this format: oai-identifier = scheme ":" namespace-identifier ":" local-identifier scheme = "oai" namespace-identifier = domainname-word "." domainname domainname = domainname-word [ "." domainname ] domainname-word = alpha *( alphanum | "-" ) local-identifier = 1*uric At the moment in Koha you can put whatever you like in OAI-PMH:archiveID and make all sorts of invalid identifiers. We should change this.
It would be good to actually have a subsystem of "global system preference" validation rules...
