DOAJ XML failed OJS 2.4.6.0

mmargale · April 28, 2015, 12:46pm

Last Monday (20/04/2015) we update to version 2.4.6 of OJS.
Now I’m trying to send information to DOAJ with the pluguin installed and gives me error:
“processing failed - Unable to parse file”

Until now the 2.4.5 version was correct, but I see that the pluguin has quite changed in this version.

Can anybody help me

Thanks.

Hi @mmargale,

The changes we made between 2.4.5 and 2.4.6 are documented here:

At the moment, the DOAJ Export Plugin provides the possibility to generate an XM…L file containing all data of a journal (including all issues and articles). But often it is necessary to upload just certain issues or articles - so in this case the XML file has to be edited manually. So it may be difficult to keep track of whether an issue / article is already uploaded or not. Furthermore there may be file size constraints in DOAJ which have to be considered. To tackle this problem it would be beneficial to have the following features (at least number 1 and 2): 1) Export single issues / articles 2) Select several issues / articles an export them 3) Flag already exported issues / articles (in order to export just the hitherto untagged issues / articles) 4) Export all changed issues / articles As this problem is part of our project we plan to implement it ourselves. Best regards, Felix

The XML structure didn’t change, but additional tools were added e.g. to only export partial content from the journal. Could you start by validating the XML against the schema file to make sure that it’s correct? See plugins/importexport/doaj/doajArticles.xsd for details. If it does validate, and you’re still getting error messages, I’d suggest contacting DOAJ to see what they say.

Thanks asmecher,

But XML is correct.

The problem is that the file doajArticles.xsd in OJS 2.4.6 is different than the doajArticle.xsd in DOAJ (https://doaj.org/static/doaj/doajArticles.xsd)

I’ve changed this file and now when I export an issue with a OJS DOAJ pluguin, DOAJ process successfully.

I am totally missing where the copy of doajArticles.xsd is even referenced in the code. All I see is the:
define('DOAJ_XSD_URL', 'http://www.doaj.org/schemas/doajArticles.xsd');
Where is it hiding?

ctgraham · April 29, 2015, 2:15pm

We also tested exports again today from journals which did not work yesterday, but without the updated doajArticles.xsd. These were successful today. I believe plugins/importexport/doaj/doajArticles.xsd is a dead file and the issue existed and was resolved on DOAJ’s end.

asmecher · April 29, 2015, 3:10pm

Hi @ctgraham and @mmargale,

DOAJ_XDS_URL is later referenced in DOAJPlugin.inc.php in the _exportJournal function. That’s the only reference.

I wonder whether DOAJ has recently changed something; I’ll check with them.

@asmecher, yes, the URL is used correctly (and the underlying schema at that link changed a NS URI recently), but I still think plugins/importexport/doaj/doajArticles.xsd is a dead file.

asmecher · April 29, 2015, 3:23pm

Hi @ctgraham,

I see what you mean – yes, that’s probably suitable for removal. No sense maintaining a local copy, particularly if it’s not used.

Hi all,

See [OJS] Enhancement for uploading metadata to DOAJ · Issue #305 · pkp/pkp-lib · GitHub for a quick note – it sounds like there was a short-lived bug over at the DOAJ website.

Hi,

I have the same problem with OJS xml export and DOAJ xml structure. I used free xml check to convert right structure. It didn’t work so is there anybody can help me.

Thanks.

asmecher · July 2, 2015, 5:49pm

Hi @oneridergisi,

Are you selecting articles for export that are not yet published? Make sure that all your articles are published; you can check by looking at the XML file for articles that don’t have a element. There shouldn’t be any.

Hi Asmecher,

I checked all xml file and it start from our early published issue to the last published issue. You can check the file from this link:

Hi @oneridergisi,

I used the xmllint XML validator to check your XML file:

 xmllint --schema doajArticles.xsd Oneri.xml

This gave me the following messages:

Oneri.xml:9: element volume: Schemas validity error : Element 'volume': This element is not expected. Expected is ( publicationDate ).
Oneri.xml:42: element volume: Schemas validity error : Element 'volume': This element is not expected. Expected is ( publicationDate ).
Oneri.xml:69: element volume: Schemas validity error : Element 'volume': This element is not expected. Expected is ( publicationDate ).
Oneri.xml:102: element volume: Schemas validity error : Element 'volume': This element is not expected. Expected is ( publicationDate ).
(...etc...)

I’d suggest checking your articles to make sure a valid publication date is set.

Hi asmecher,
Thank you for your help on this matter. After a long research I find to problem (publicationDate) and I fix it. It is coming from our xml export and there are structural problem with it.

Thanks,

Hello oneridergisi,
I am facing the same problem (OJS 2.4.5.0). Could you tell me what was exactly the probelm with the publicationDate and how you fixed it.
Thanks a lot,
Antonie
