<DIV>Morning all,</DIV>
<DIV> </DIV>
<DIV>I made a bit of a mess. </DIV>
<DIV>A while back I uploaded some PDF documents to DSpace and ran Filter media to extract the text. Recently the creators of the pdf files sent me a batch with updated volume numbers etc to replace the existing ones already on the server. So I simply removed the items and added new bitstreams. And in the back of my mind I remember something about that not really being the right thing to do.</DIV>
<DIV>Now when I run the filter media process again the text doesn't get extracted - could this be because the checksums don't match or because the original was located in one assetstore and the new one in another?</DIV>
<DIV> </DIV>
<DIV>Thank you in advance</DIV>
