Hello,
in 2007, january, the ISBN will be on 13 digits. afaik, it will use the standard vendor code, that for instance is : 978+ (isbn-controldigit) +controldigit re-calculated.
Yes, it is. You can find all information from ISBN Users' Manual (ISBN-13). http://www.isbn-international.org/en/manual.html
What will we have to do in Koha ? * modify the DB to handle this longer ISBN
It is the must. check 10 and 13 digits automatically.
* re-calculate all previously entered ISBN ?
Need not change any issued 10 digits ISBN. Unused 10 digits ISBN still valid even after 2007, january.
* rewrite show-isbn-with-dash sub ?
Koha need minor change to handle this.
* that's all ?
