Hi Phil,
Looks like devious usage of dcterms xml :)
I'm sure a metadata purist would not be so happy, but from sword's point of
view this is all fine. I guess either way you need to modify the ingester
on the repository end to pull out all your special attributes, and so if
you wanted to be less-dc about it, you could just replace the existing
ingester which understands the full OJS export format.
Just thinking out loud: OJS has a native export format (which contains the
base64 encoded files) and also supports the DOAJ format. Would be cool if
they were available over sword, and if there was an ingester for DSpace
that could handle them. Probably wouldn't be an enormous amount of work,
either!
Cheers,
Richard
