1.90 matthew 71:
72: lonpublisher - LON-CAPA publishing handler
73:
1.94 harris41 74: =head1 SYNOPSIS
1.90 matthew 75:
1.94 harris41 76: B<lonpublisher> is used by B<mod_perl> inside B<Apache>. This is the
77: invocation by F<loncapa_apache.conf>:
78:
79: <Location /adm/publish>
80: PerlAccessHandler Apache::lonacc
81: SetHandler perl-script
82: PerlHandler Apache::lonpublisher
83: ErrorDocument 403 /adm/login
84: ErrorDocument 404 /adm/notfound.html
85: ErrorDocument 406 /adm/unauthorized.html
86: ErrorDocument 500 /adm/errorhandler
87: </Location>
88:
89: =head1 DESCRIPTION
90:
91: B<lonpublisher> takes the proper steps to add resources to the LON-CAPA
1.90 matthew 92: digital library. This includes updating the metadata table in the
93: LON-CAPA database.
94:
1.94 harris41 95: B<lonpublisher> is many things to many people.
1.90 matthew 96:
97: This module publishes a file. This involves gathering metadata,
98: versioning the file, copying file from construction space to
99: publication space, and copying metadata from construction space
100: to publication space.
101:
1.94 harris41 102: =head2 SUBROUTINES
103:
104: Many of the undocumented subroutines implement various magical
105: parsing shortcuts.
