=head1 NAME |
|
|
|
lonpublisher - LON-CAPA publishing handler |
|
|
|
=head1 SYNOPSIS |
|
|
|
B<lonpublisher> is used by B<mod_perl> inside B<Apache>. This is the |
|
invocation by F<loncapa_apache.conf>: |
|
|
|
<Location /adm/publish> |
|
PerlAccessHandler Apache::lonacc |
|
SetHandler perl-script |
|
PerlHandler Apache::lonpublisher |
|
ErrorDocument 403 /adm/login |
|
ErrorDocument 404 /adm/notfound.html |
|
ErrorDocument 406 /adm/unauthorized.html |
|
ErrorDocument 500 /adm/errorhandler |
|
</Location> |
|
|
|
=head1 DESCRIPTION |
|
|
|
B<lonpublisher> takes the proper steps to add resources to the LON-CAPA |
|
digital library. This includes updating the metadata table in the |
|
LON-CAPA database. |
|
|
|
B<lonpublisher> is many things to many people. |
|
|
|
This module publishes a file. This involves gathering metadata, |
|
versioning the file, copying file from construction space to |
|
publication space, and copying metadata from construction space |
|
to publication space. |
|
|
|
=head2 SUBROUTINES |
|
|
|
Many of the undocumented subroutines implement various magical |
|
parsing shortcuts. |
