Hi Richard et al., So sorry for the glacially slow reply. I'm not sure about the header idea. I haven't given it much thought, to be honest. I did want say, "Yes! Exactly!" to you saying, "the schema didn't even come close to fitting dcterms" because in integrating Dataverse (my side) and Open Journal Systems (their side) we agreed upon what I've been calling "the XML attribute" hack to pack more (desperately needed) information into a dcterms XML element. This is best illustrated by example, I believe. Sure we support run-of-the-mill dcterms elements like this... <dcterms:title>Roasting at Home</dcterms:title> <dcterms:creator>Peets, John</dcterms:creator> <dcterms:creator>Stumptown, Jane</dcterms:creator> <dcterms:publisher>Coffee Bean State University</dcterms:publisher> ... but in order to get the article citation from OJS into Dataverse, we special case the "dcterms:isReferencedBy" element, allowing OJS to put extra XML attributes (DDI stuff like holdingsURI, agency, and IDNo) into the XML element like this: <dcterms:isReferencedBy holdingsURI="http://dx.doi.org/10.1038/dvn333" agency="DOI" IDNo="10.1038/dvn333">Peets, J., & Stumptown, J. (2013). Roasting at Home. New England Journal of Coffee, 3(1), 22-34.</dcterms:isReferencedBy> It gets the job done AND I just learned today at http://irclog.iq.harvard.edu/dvn/2014-05-01#i_8982 that OJS got this "hack" merged into the PHP bindings for SWORD in this pull request: Allow attributes on dcterms elements in Atom entries by jwhitney · Pull Request #6 · swordapp/swordappv2-php-library - https://github.com/swordapp/swordappv2-php-library/pull/6 So maybe we (Dataverse and OJS) are not so off the mark with this... "interpretation" of SWORD... but I certainly feel like this isn't in the official spec and I don't know if this sort of thing is supported in any other client or server libraries. Phew! Glad to get that off my chest! :) Phil On Mon, Feb 10, 2014 at 1:42 PM, Richard Jones <ri...@co...> wrote: > Hi Phil, > > We have been doing this for the Duo project in Oslo.
