Hi,

(For the benefit of other people on the list)

This problem was caused by a bug in the explode_metadata_database.pl
script, which I've fixed. You can download an updated version of this
file from
http://www.cs.waikato.ac.nz/~mdewsnip/greenstone/temp-2.63/explode_metadata_database.pl
(it goes in the Greenstone "bin/script" directory).

Exploding Lucia's database on my machine seemed to be unreasonably slow,
and I tracked this down to some built-in Java code. I've managed to work
around this code and exploding databases is now significantly faster (at
least on my machine). This improvement will be included with Greenstone
v2.70.

Regards,

Michael
