Description Tomás Cohen Arazi 2016-01-08 13:39:50 UTC
Created attachment 46429 [details]
Original style

Both EPrints and DSpace projects ship XSLT stylesheets that are included in the OAI response so using a web browser to navigate the repository. We should add one ourselves.

See the attached screenshots for better understanding this enhancement proposal.

It doesn't work for me when your stylesheet is in opac-tmpl/xsl/. I have to put it in opac-tmpl directly, and modify Repository.pm file to make it works. Could you try on your side? I've seen in your screenshot you're working with 'localhost' as your server URL. It may come from there.

A remark: you introduce a new syspref OAI-PMH:CustomStylesheet. I think that
this kind of parameter belongs to the 'Extended Mode'. The YAML config file
could be used to link to a local stylesheet.

I'm using kohadevbox:ansible. I think the permissions (apache ones) on a regular dev/normal install have diverged from the packages. I'll take a look.

That's probably a good idea. I'll dig into it.

This part in apache conf is the culprit:

<DirectoryMatch "__OPAC_WWW_DIR__/.*/(modules|xslt|includes)">
   Order deny,allow
   Deny from all
</DirectoryMatch>

I will propose a patch fixing that, and using OAI server conf file to define custom XSLT for web view.

Tomás, I've signed-off your first patch, and obsoleted the 2 others. You should take a look at mine (2nd patch attached) and sign it whether it seems OK to you. Maybe a third eye (Hector) and sign-off would be welcome. Thanks for the good job.

For me looks very good I'll signed-off if you don't care Tomás.

What's the point of this change? I personally prefer the previous version.

The $conf variable is used above (line 148) in order to get the new extended 'xslt' parameter:

148     $response->xslt(
149         $conf && $conf->{xslt}
150           ? $conf->{xslt}
151           : "/opac-tmpl/bootstrap/css/OAI.xslt"
152     );
Comment 16 Jonathan Druart 2016-01-19 10:07:33 UTC
QA comments:
1/ Could you please add the DSpace license (linked to the xslt) to the about page?
2/ Frédéric, why did you move the xslt file to the OPAC css dir? Why not koha-tmpl/opac-tmpl/bootstrap/en/xslt/?
Comment 17 Jonathan Druart 2016-01-19 10:09:35 UTC
3/ Should the new file be translatable?

See comment 8. The XSL file is accessed directly by the web browser by http. Files in koha-tmpl/opac-tmpl/bootstrap/en/xslt/ can only be accessed by Koha web scripts.

In my opinion, humble as appropriate, no.
Comment 20 Frédéric Demians 2016-03-03 08:21:26 UTC
What point(s) prevent this patch to return to 'signed-off' status?
Comment 21 Kyle M Hall 2016-03-03 17:29:56 UTC
I think the issue at hand is that this patch revealed a new bug in testing where the non-package version of Koha's apache conf no longer matches the package version in behavior and functionality. While appreciated, I think Frédéric's followup is not needed and we should instead fix the bug for non-package installs of Koha. That should solve the issue and once that and the license followup have been submitted this can move forward.

I agree with this plan...

Where is located the Apache conf file? Do you already know what is its difference with etc/koha-http.conf?

My followup patch was also introducing a way to specify a local XSLT in extended mode. See this:

https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=46460&action=diff

But it could be added later when this patch will be in master.

I agree. I think it would be good as a followup on a new bug report. I believe Tomás is going to file the bug and patch for the issue at hand.

This is still valid.

Bug 15527: Add a stylesheet for OAI-PMH to aid usability

This patch introduces an XSLT file grabbed from DSpace and a couple
css files.

To test:

- Point to your dev Koha's oai endpoint. For example:
  http://localhost:8080/cgi-bin/koha/oai.pl?verb=ListMetadataFormats
=> FAIL: Look how ugly it is for humans.
- Apply this patch
- Reload
=> SUCCES: It is styled and provides really useful links to interact with
  the OAI server verbs.
- Sign off :-D
