=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 OVERVIEW |
| |
|
| |
Authors can only write-access the C</~authorname/> space. They can |
| |
copy resources into the resource area through the publication step, |
| |
and move them back through a recover step. Authors do not have direct |
| |
write-access to their resource space. |
| |
|
| |
During the publication step, several events will be |
| |
triggered. Metadata is gathered, where a wizard manages default |
| |
entries on a hierarchical per-directory base: The wizard imports the |
| |
metadata (including access privileges and royalty information) from |
| |
the most recent published resource in the current directory, and if |
| |
that is not available, from the next directory above, etc. The Network |
| |
keeps all previous versions of a resource and makes them available by |
| |
an explicit version number, which is inserted between the file name |
| |
and extension, for example C<foo.2.html>, while the most recent |
| |
version does not carry a version number (C<foo.html>). Servers |
| |
subscribing to a changed resource are notified that a new version is |
| |
available. |
| |
|
| |
=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. |
