I'm not sure I understand what you mean here by "method", since the first method is the sequence. > But, you would need to do some customizations to the UI to > ensure it was somehow determining the next unique handles to assign. Here I thought generating the handle has nothing to do with UI, because the handle.handle column contains '12345/6789'. So I imagined if I changed only the generating code, there would be nothing to change in the reading/UI part. Is this wrong? What if I only changed this (dspace/etc/oracle/update-sequences.sql:97): @updateseq.sql handle_seq handle "to_number(regexp_replace(handle, '.*/', ''), '999999999999')" "WHERE REGEXP_LIKE(handle, '^.*/[0123456789]*$')" > But, should you go this route, I'm sure others would be interested in the work > (and it could also lead towards a new feature in a future version of > DSpace). I'm afraid I don't have the Java skills needed, so anything may I do will probably be limited to my simple use case of a static prefix to the local handle part. Though I can imagine other useful use cases - like generating a prefix for each comunity, i.e. "/comm1.1234", "comm2.1234" and some less useful ones like a hash or UUID.
