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

85: =head1 OVERVIEW
86:
87: Authors can only write-access the C</~authorname/> space. They can
88: copy resources into the resource area through the publication step,
89: and move them back through a recover step. Authors do not have direct
90: write-access to their resource space.
91:
92: During the publication step, several events will be
93: triggered. Metadata is gathered, where a wizard manages default
94: entries on a hierarchical per-directory base: The wizard imports the
95: metadata (including access privileges and royalty information) from
96: the most recent published resource in the current directory, and if
97: that is not available, from the next directory above, etc. The Network
98: keeps all previous versions of a resource and makes them available by
99: an explicit version number, which is inserted between the file name
100: and extension, for example C<foo.2.html>, while the most recent
101: version does not carry a version number (C<foo.html>). Servers
102: subscribing to a changed resource are notified that a new version is
103: available.
1.94 harris41 104:
105: =head1 DESCRIPTION
106:
107: B<lonpublisher> takes the proper steps to add resources to the LON-CAPA
1.90 matthew 108: digital library. This includes updating the metadata table in the
109: LON-CAPA database.
110:
1.94 harris41 111: B<lonpublisher> is many things to many people.
1.90 matthew 112:
113: This module publishes a file. This involves gathering metadata,
114: versioning the file, copying file from construction space to
115: publication space, and copying metadata from construction space
116: to publication space.
117:
1.94 harris41 118: =head2 SUBROUTINES
119:
120: Many of the undocumented subroutines implement various magical
121: parsing shortcuts.
