Dear Sir, Thank you for your input on the forum. I want to know how do you integrate the two difference repositories (KOHA Catalogues which is MARC21 Compliance & DSPACE Catalogue which is Dublin Core Compliance), What is synchronization method of the meta data and other Administrative (User/Patron Records) data between the system. Does KOHA & DSPACE are installed & implemented separately? I have the same requirements of ILS & DL system but I dont know how it works together? Thank you Regards, Ateeq
