[EP-tech] Atom.xsl Patch Submission
Thanks for submitting this patch.
The ?yomiko? part is a good catch.
When I export something as Atom, I get these category elements:
<category term="article" label="Article" scheme="http://eprints.whiterose.ac.uk/data/eprint/type"/>
<category term="archive" label="Live Archive" scheme="http://eprints.org/ep2/data/2.0/eprint/eprint_status"/>
These are generated here: https://github.com/eprints/eprints/blob/3.3/perl_lib/EPrints/Plugin/Export/Atom.pm#L258-L272
The ?eprint_status? one uses the eprints.org namespace ? which I think is what should possibly be used instead of ?yomiko? [EPrints Services: how does 3.4 (without a default ?flavour?) handle this?].
The ?type? one uses the repository namespace ? I think because these can be configured at the repository level.
I have created this pull request: https://github.com/eprints/eprints/pull/419 for this.
For the ?subjects? part, in EPrints, the subjects field is normally a controlled-value field, based on the ?subjects? dataset.
If values added to the subject field don?t exist in the subjects dataset, EPrints doesn?t break ? but they will render like this:
?? value ??
? which isn?t normally what is wanted.
By default (in the perl_lib Atom.xsl file), I think it?s safer to *not* map the dcterms:subject into the subjects field (I haven?t done this in the pull request above).
To achieve the improved import of data for Artivity, I would either
(i) make a new XSL import mapping (see warning below!):
~/archives/ARCHIVEID/cfg/plugins/EPrints/Plugin/Import/XSLT/ArtivityAtom.xsl (change the attribute to ept:name=?Artivity Atom XML?)
Or (ii) override the default Atom plugin:
!! WARNING !!
I?m not sure how the code here: https://github.com/eprints/eprints/blob/3.3/perl_lib/EPrints/Plugin/Import/AtomMultipart.pm#L96-L113 will behave when there are multiple plugins defined that can handle application/atom+xml imports. If you have two plugins: Atom.xsl and ArtivityAtom.xsl, things might not work. I haven?t tested this (please let us know if you go down this route and it works!).
Also, I?ve never over-ridden an XSL plugin. To override perl EPrints plugins this is the way to do it:
I?m not sure if you?d need to, or how you would define the ?plugin_alias_map? aspect?

Subject: [EP-tech] Atom.xsl Patch Submission
I have found the reason why the category id and subjects are not recognized when depositing files in E-Prints using the Atom Publishing Protocol. The XSLT stylesheet 'Atom.xsl'  in the Import directory does not handle those elements when converting Atom to EPrints XML.
Please find attached a version of the file which handles the dcterms:type and dcterms:subject terms and translates them into E-Prints XML. The dcterms vocabulry seems to be widely used in SWORD protocol implementations (i.e. ).
Additionally, I corrected a line in the stylesheet which transforms a submitted eprints status. The line checked for the status being equal to 'MailScanner has detected a possible fraud attempt from "yomiko.ecs.soton.ac.uk80" claiming to be http://yomiko.ecs.soton.ac.uk:8080/data/eprint/status/<http://yomiko.ecs.soton.ac.uk:8080/data/eprint/status/>'. It seems to me that this is a concrete EPrints instance, so the line would not work for any other EPrints instance. I changed the line to: 'contains(@scheme,'/eprint/status')'. This should work for all EPrints instances, including my test server.
Please let me know if you will be including my patch into the repository.
