One last note Patrick...I just realized, your commands are slightly "wrong" (though I'm not sure if this is the cause or not).
With the "manifestOnly=true" option, DSpace will only export mets.xml files. You look to be trying to create a ZIP package (harvest_test-aip.zip). But, in reality the AIP Export is creating *XML* files only. If you want to generate a Zip package, you then you need to remove the "manifestOnly=true" option. I'm not sure that this is the cause of your issues though. But, I wanted to be clear that "manfiestOnly=true" only creates XML files (with just metadata, and no content files). - Tim On Thursday, August 18, 2011 10:59:11 AM, Tim Donohue wrote: > Hi Patrick, > > A few questions for you: > * What version of DSpace are you using? 1.7.0, 1.7.1 or 1.7.2? > * Just a generic question -- is there a reason why you want to run this > in "manifestOnly=true" mode?
