Hi !
<p>This is good idea and it will save lot of time.
<p>We did similar work for Wimpy-Point and Glossary (PGSQL only) that can be found here : https://openacs.org/new-file-storage/one-file.tcl?file_id=434
<p>Currently ns_xml module can be used to export/import but I think there are efforts underway to replace it with TCLDOM etc, but for time being ns_xml should be ok.
