TRIM export contents

A TRIM export consists of

• A manifest of the transfer (manifest.txt)
• XML schema documentation for all xml files in the transfer (container, location and document xml metadata)
• Location metadata (Location.xml)
• Container metadata (ContainerMetadata.xml)
• Document metadata (eg DOC_2012_000100_Metadata.xml)
• Documents (eg DOC_2012_000100.docx)

Processing a TRIM export

Parsing contents to the SIP

• Each container becomes a single transfer OR each transfer is broken into one SIP per container
• The md5 checksums present in each document metadata file are verified
• manifest.txt is copied to /metadata/submissionDocumentation
• Location.xml is copied to /metadata
• All schema documentation is copied to /metadata
• The relevant ContainerMetadata.xml is copied to /metadata
• The relevant document metadata files are copied to /metadata
