If your bothering to encode the Handle into a QR code, and you are
registered with handle.net, I would use that handle.net version of your
handle instead of your local repository's domain. (i.e. persistance of URL).
As Steve said you could be having URL encoding issues, try doing a log.info()
to see if you are generating the right URL.
We've had two projects locally with making cover pages for our PDF's.
One was to build a curation task, that an administrator can run over a
collection, and will move the original PDF to a bundle called PRESERVATION,
and put the cover-page version into a bundle called DISPLAY. We also then
changed the UI to link to the DISPLAY bundle version of the PDF with the
cover-page attached to it.
The other implementation of this same thing is to go back to the OAIS
reference model (SIP, AIP, DIP), keep the ORIGINAL bundle PDF alone (our
AIP), but to intercept requests for it and make a cover-page version of
that PDF on-the-fly in response to the request, and serve that (DIP).
As much as we've thought that the on-the-fly generation of a citation PDF
would slow us down, at least on development (quad-core i7 with
solid-state), it only adds a marginal delay (100-200ms).
We too have put the QR code on the page. I'm not sure if that will stay on
the cover-page when we deploy this to production, but we've been looking at
it.
We are using the itextpdf library, instead of the Google Charts API.
BarcodeQRCode qrCode = new BarcodeQRCode(handleURI, 100, 100, null);
Our code for the curation / citation-PDF is at:
https://github.com/osulibraries/DSpaceOSUKB/tree/citation-pdf
There's no public write-up or documentation yet, as this is still in
development.
