Re: [sword-app-tech] migrate DSpace to Islandora using SWORD

[Glen R. <gle...@ll...>]

Hi Mark,

I think I've misunderstood what Ying was trying to do, I though it was a plain METS document being submitted rather than a METS document in a zip file which was why you would need a http URL or relative file URL for the sword-fedora plugin to find what it needs to ingest. If you want to submit a zip file with a METS manifest you could use a mime-type of application/zip and a packaging of http://www.loc.gov/METS/ and looking at the code it will add any dmdSecs as metadata datastreams in Fedora and any files it finds in the zip file. 

Its not the ideal way of doing it as you mention below, ideally it should take the METS file as a manifest and understand the myriad of URL possibilities and only ingest the items mentioned in the METS file but the way it works currently may be enough to get Ying started. As it currently doesn't parse the METS:file section it shouldn't matter if the LOCTYPE is URL or something else (assuming I'm reading the code correctly).

Sorry for the confusion but hope this is a possible solution.

Thanks

Glen

The best solution is probably to change the links to http URLs if you can and if not if you could change the file paths to absolute (assuming the files are on the same server the fedora sword web app is installed).
