current Fedora based digital repository, which is using MODS as the
metadata standard. <br><br>I am writing to ask is there metadata crosswalk documentation already developed between DDI 3 and MODS or METS? Would you please give me some guidance on that?<br><br>I have found one from the the VDCIntegration Wiki (http://pledge.mit.edu/index.php/VDCIntegration), but only very brief DDI fields were mapped. Are there more detailed mapping developed?<br><br>Also, how DDI is comparable for using in archiving science data? Are there research/practice on the topic? If an institutional data repository is trying to develop its metadata standard in order to be able archive research data in both social sciences and sciences subjects, what would you suggest on that?<br><br>Thank you!<br><br><div><span name="x"></span>-- <br>Minglu Wang<br>Data Services Librarian<br>John Cotton Dana Library<br>Rutgers, The State University of New Jersey<br>185 University Avenue<br>Newark, New Jersey 07102-1814 <br><br>Telephone: (973)353-3810<br>Email: minglu@rutgers.edu<br><span name="x"></span><br></div><br></div></body></html>
