Never mind! I found a rogue entry in plugin.pl on live that was causing confusion. All sorted now.

Okay, so it’s all working in my test environment but not on live and I can’t work out why.

I’ve copied the LocalRSS2.pm file over into archive/myarchive/cfg/plugins/EPrints/Plugin/Export, restarted Apache and regenerated views and abstracts. There are no RSS2 icons at all showing on the abstract pages and when I try to access http://eprints.lincoln.ac.uk/cgi/exportview/creators/uid/LocalRSS2/uid.xml where I expect the feed to be found I get an Error in export page, i.e. http://eprints.lincoln.ac.uk/cgi/exportview/creators/726/LocalRSS2/726.xml.

I’ve checked perl_lib/EPrints/Plugin/Export and RSS2.pm is in there, so it’s not missing the master file – I’m not sure what’s not there. The fact that the basic RSS2 feed isn’t showing makes me wonder if it’s a server set up issue, maybe a missing perl module?

Add

sub is_feed { return 0; }

Which will keep it as an export plugin but prevent it being in the list of feeds on search and view pages.

So! Any ideas how I stop the RSS icon for this feed showing up on browse views? :D

Thanks for all the replies – changing the RegEx and the date has worked, however there is the issue now that some of our data contains incomplete dates. I’m working on adding in some extra regex checks to pad the dates as necessary and that seems to be effective so far!

 

I’ve got some other bits to clean up on EPrints before 2018 so you may not have heard the last of me 😉 (Not a threat, honest!)

Thanks for responses guys.

I totally agree that this isn't the correct use for this feed but I'll bite my tongue lest I say something unprofessional ;)

My comment about the date was more that this isn't the date we need, rather than it was incorrect for its purpose.

Of course I'll be implementing this in a unique feed! :)

I'll take a look at suggestions tomorrow and let you know how I get on.

On a related note, I'll be moving off EPrints work at the University as of next January following a reshuffle of staff roles. I'll still be here but my focus will be more on library systems development, so some of us may cross paths again in the future. But thanks to everyone on this list for the help and support over the last few years (and beer for those who I've met in person in places like Dublin and Edinburgh!) I won't pretend I've come away knowing everything about EPrints; the code still baffles me on a number of levels which I find frustrating as someone who has coded for a living for 15 years, but I'm thankful for your patience, especially as I've been working on moving our repository to its new home. I'm not sure who at Lincoln will be replacing me on EPrints duty but whoever it is will get a recommended list of names of people to badger ;)

Once again, a massive thanks, I'll let you know how I get on with this feed.

Yes, what John said :)

By the way, for some of our sites, we use the normal views feature for this. Every /view/ page can have a .include file. eg.

https://eprints.soton.ac.uk/view/people/bf4af598-26bf-47f4-a0a4-800095a23eb5.html

has a matching

https://eprints.soton.ac.uk/view/people/bf4af598-26bf-47f4-a0a4-800095a23eb5.include

with just the HTML of the main bit in. Handy to include elsewhere.

Ah, Mr. Gutteridge…  close, but no cigar! :o)

 

The 'date' field normally doesn't include the time component - so the regex

/^(\d{4})-(\d{2})-(\d{2}) (\d{2}):(\d{2}):(\d{2})$/

won't match. This should:

/^(\d{4})-(\d{2})-(\d{2})$/

 

*BUT* I'd advise against updating the RSS2 feed to do this. People may be using it in the way it's intended.

I'd subclass the RSS2 feed - adding your new date sorting method.

-OR- configure an author browse view, and use the RSS links embedded in them (or pull in the .include version of the view page).

 

Cheers,

John

That's the correct behaviour for an RSS feed. I'm guessing the logic of this is that your website has an RSS importer already that makes it the desired route.

Both "date" and "datestamp" should be stored in the same format in EPrints, so you should just have this:

my $datestamp = $eprint->get_value( "date" );

                                if( $datestamp =~ /^(\d{4})-(\d{2})-(\d{2}) (\d{2}):(\d{2}):(\d{2})$/ )

                                {

                                                my $time = timelocal( $6, $5, $4, $3, $2-1, $1 );

                                                $item->appendChild( $session->render_data_element(

                                                                2,

                                                                "pubDate",

                                                                EPrints::Time::rfc822_datetime( $time ) ) );

                                }

So now it's an RSS feed with the dates of the items in the catalogue, rather than of catalogue records.

Okay, so the goalposts have shifted on this since talking in more detail with our ICT team!

 

Basically, our repository feeds our staff directory pages in real time using the available feeds; specifically this feed: http://eprints.lincoln.ac.uk/cgi/exportview/creators/userid/RSS2/userid.xml. I did question why the RSS2 feed was being used and received the answer that this particular feed formats up a “Description” which can be pulled straight into the staff profiles which are then ordered based on the date on the record. So far, so good, but the issue at hand is those dates. I initially thought the problem was the format that the dates were coming out in and proposed that we include the records pre-formatted citation in the standard XML feed for them.

 

However, it now transpires that the date on the RSS2 feed is just plain wrong; it’s using the datestamp, when the record was created, rather than the date that the article, book etc was published, as stored in the date field. For the academics this means that the records on their staff profile are not in publication order. So we come back to the decision – use the standard XML file and add the citation, or change the RSS2 template to use the published date rather than the created date. ICT would prefer the latter so that they don’t have to change the staff directory code.

 

I’ve been taking a look at the latter an I think I’ve found the chunk in the RSS2 script that deals with the date:

 

my $datestamp = $eprint->get_value( "datestamp" );

                                if( $datestamp =~ /^(\d{4})-(\d{2})-(\d{2}) (\d{2}):(\d{2}):(\d{2})$/ )

                                {

                                                my $time = timelocal( $6, $5, $4, $3, $2-1, $1 );

                                                $item->appendChild( $session->render_data_element(

                                                                2,

                                                                "pubDate",

                                                                EPrints::Time::rfc822_datetime( $time ) ) );

                                }

 

I tried tweaking this to change datestamp to date, however this completely removed the date from the feed. I’m guessing that this is something to do with how the RegEx decides to proceed on the if statement. So I thought I’d see what happened if I just pushed the date straight into the element which… didn’t work…

 

                                $item->appendChild( $session->render_data_element(

                                                2,

                                                "pubDate",

                                                EPrints::Time::rfc822_datetime( $eprint->get_value( "date" ) ) ) );

 

I’m sure there’s obvious reasons for that which I probably can’t see (I always feel code dyslexic when I look at EPrints source for some reason…) Personally I’d prefer to push the citation in a more capable feed than RSS2 but I think I’m going to be at the behest of the Staff Directory here.

Unless that field has

    export_as_xml => 0,

 

- like the suggestions field does by default…

 

What are you trying to achieve with your export?

Personally, I'd suggest subclassing that plugin, and adding a citation to it that way - as always, TMTOWTDI!

It depends on how and when you'll be calling the plugin.

 

If it's for active, user-generated requests, Adam's method may be more suitable, as the processing is done when a record is saved, rather than when a record is requested.

Hi Andrew

 

                The XML export just exports all the fields on an object.  I wouldn’t modify it if I were you.  The simplest way would be to add a new field to your item.

 

                I’m not sure if virtual fields come out in the XML export, but if they do, adding a virtual field to your object may be the easiest way to do this.  Alternatively, use an automatic field and write the citation to it.  See

https://wiki.eprints.org/w/Training_Video:Virtual_Fields and https://wiki.eprints.org/w/Training_Video:Automatic_Fields

Hi all,

 

Just took a dive into the EPrints XML export template (perl_lib/EPrints/Plugin/Export/XML.pm) to try and add a node for the records citation to it and I can’t see where you would do this? Is there somewhere separate that defines what data it pulls through?

 

Cheers in advance!
