I use greenstone version 2.50 under linux system(ferdo 1). When I build a oai
collection, I could not edit the metadata using the interface windows, because I
could not see any metadata at the enrich window. However, if I build another
collection like demo using metadata.xml in the import folder, I could see the
metadata at the enrich window of interface. I am wondering how I can edit the
metadata using the interface when I build a oai collection or other collections.
