48: =head1 NAME
49:
50: lonpublisher - LON-CAPA publishing handler
51:
52: =head1 SYNOPSIS
53:
54: B<lonpublisher> is used by B<mod_perl> inside B<Apache>. This is the
55: invocation by F<loncapa_apache.conf>:
56:
57: <Location /adm/publish>
58: PerlAccessHandler Apache::lonacc
59: SetHandler perl-script
60: PerlHandler Apache::lonpublisher
61: ErrorDocument 403 /adm/login
62: ErrorDocument 404 /adm/notfound.html
63: ErrorDocument 406 /adm/unauthorized.html
64: ErrorDocument 500 /adm/errorhandler
65: </Location>
66:
67: =head1 OVERVIEW
68:
69: Authors can only write-access the C</~authorname/> space. They can
70: copy resources into the resource area through the publication step,
71: and move them back through a recover step. Authors do not have direct
72: write-access to their resource space.
73:
74: During the publication step, several events will be
75: triggered. Metadata is gathered, where a wizard manages default
76: entries on a hierarchical per-directory base: The wizard imports the
77: metadata (including access privileges and royalty information) from
78: the most recent published resource in the current directory, and if
79: that is not available, from the next directory above, etc. The Network
80: keeps all previous versions of a resource and makes them available by
81: an explicit version number, which is inserted between the file name
82: and extension, for example C<foo.2.html>, while the most recent
83: version does not carry a version number (C<foo.html>). Servers
84: subscribing to a changed resource are notified that a new version is
85: available.
86:
87: =head1 DESCRIPTION
88:
89: B<lonpublisher> takes the proper steps to add resources to the LON-CAPA
90: digital library. This includes updating the metadata table in the
91: LON-CAPA database.
92:
93: B<lonpublisher> is many things to many people.
94:
95: This module publishes a file. This involves gathering metadata,
96: versioning the file, copying file from construction space to
97: publication space, and copying metadata from construction space
98: to publication space.
99:
100: =head2 SUBROUTINES
101:
102: Many of the undocumented subroutines implement various magical
103: parsing shortcuts.
