1.90 matthew 67:
68: lonpublisher - LON-CAPA publishing handler
69:
1.94 harris41 70: =head1 SYNOPSIS
1.90 matthew 71:
1.94 harris41 72: B<lonpublisher> is used by B<mod_perl> inside B<Apache>. This is the
73: invocation by F<loncapa_apache.conf>:
74:
75: <Location /adm/publish>
76: PerlAccessHandler Apache::lonacc
77: SetHandler perl-script
78: PerlHandler Apache::lonpublisher
79: ErrorDocument 403 /adm/login
80: ErrorDocument 404 /adm/notfound.html
81: ErrorDocument 406 /adm/unauthorized.html
82: ErrorDocument 500 /adm/errorhandler
83: </Location>
84:
85: =head1 DESCRIPTION
86:
87: B<lonpublisher> takes the proper steps to add resources to the LON-CAPA
1.90 matthew 88: digital library. This includes updating the metadata table in the
89: LON-CAPA database.
90:
1.94 harris41 91: B<lonpublisher> is many things to many people.
1.90 matthew 92:
93: This module publishes a file. This involves gathering metadata,
94: versioning the file, copying file from construction space to
95: publication space, and copying metadata from construction space
96: to publication space.
97:
1.94 harris41 98: =head2 SUBROUTINES
99:
100: Many of the undocumented subroutines implement various magical
101: parsing shortcuts.
