Of course systems should still read 10 digit ISBNs, but only 13 digit
ISBNs are issued.
This is not a problem for your proposed microformat per se, but I
just wanted to make sure
everyone involved in the discussion which will start around your isbn
format is up to date
on current ISBN standards. Also a extension which reads ISBN numbers
automatically convert any 10 digit ISBNs to their 13 digits
equivalent for use with other
I think disallowing 10 digit ISBNs in the microformat is not a good
idea as there may be
websites that want to mark up their existing ISBN lists.
