For this, JOpac2  is written in Java and is build on a class structure that make easy to load data in any ISO2709 format (ISIS, UNIMARC and text-only if you map it on a ISO2709 structure). JOpac2  is currently used by the University of Trieste for two small catalogs: non SBN data from a old ISIS based system  and a journal catalog . Now at v.1.0, we are working for a new release and a loan module."
