Limiting names shown

Although all names should be shown for exports, sometimes an EPrint has so many creators or editors it is really not useful to display then all without user prompting. Therefore, a render function (in lib/cfg.d/limit_names_shown.pl) has been written for EPrints 3.4.2+ to allow some names to be hidden and then displayed when a link on "et al" is clicked. Below describes how you can make good use of the render function:

1. Edit your archive's cfg/cfg.d/eprint_fields.pl and create a virtual field replica of the name field on which you want to be able to limit authors. The example bellow will limit the number of creators display to 10 before showing an "et al" so you can display the rest.

{
        name => 'creators_name_limited',
        type => 'name',
        virtual => 1,
        render_value => 'limit_names_shown',
        render_limit => 10,
        render_dynamic => 1,
},

render_dynamic determines whether the "et al" gets made into a link that will reveal the other names. If it is not included or set to 0, the et al will not be a link and remaining names will not be displayable.

2. Copy your archive's cfg/citations/eprint/default.xml (or cfg/citations/eprint/default_for_summary_page.xml if it exists) to cfg/citations/eprint/display.xml.

3. Edit cfg/citations/eprint/display.xml adding _limited to all the name fields you want to limit the number of names initially displayed.

4. Edit your archive's cfg/citations/eprint/summary_page.xml and cfg/citations/eprint/result.xml replace item.citation('default') (or item.citation('default_for_summary_page')) with item.citation('display'). (N.B. you may need to modify other citation styles if they have been created for your archive). If the summary_page.xml and result.xml do not already exists in you archive, you need to copy these from flavours/pub_lib/citations/eprint/ to you archive and then edit these files within the archive's cfg/citations/eprint/ directory.

5. Refresh abstract pages. Either by clicking the Refresh Abstracts button in the Config. Tools tab of the Admin page or by running the following command as the eprints user (substituting ''EPRINTS_PATH and ARCHIVE_NAME appropriately):

EPRINTS_PATH/bin/epadmin refresh_abstracts ARCHIVE_NAME

6. Reload the webserver, using the appropriate command for your particular Linux operating system. E.g.

root@redhat> apachectl graceful
root@ubuntu> apache2ctl graceful

If you want to use limited names citations for search results and browse views, then you will need to make similar changes to cfg/citations/eprint/default.xml and cfg/citations/eprint/result.xml. Like for updating abstract pages, you will need to click Refresh Views button in the Config. Tools tab of the Admin page or by running the following command as the eprints user (substituting 'EPRINTS_PATH and ARCHIVE_NAME appropriately):

EPRINTS_PATH/bin/epadmin refresh_abstracts ARCHIVE_NAME

If you have updated either browse view or search result citations, you will also need to reload the webserver (see step 6 above).

If you want to update all citations, then technically you need only modify (like described in step 3) the cfg/citations/eprint/result.xml' and cfg/citations/eprint/default.xml (and cfg/citations/eprint/default_for_summary_page.xml) citation files and need not create a cfg/citations/eprint/display.xml nor modify cfg/citations/eprint/summary_page.xml (steps 2 and 4). However, you will still need to run refresh abstracts, refresh views and reload the webserver.
