35: =head1 NAME
36:
37: Apache::lonmsg: supports internal messaging
38:
39: =head1 SYNOPSIS
40:
41: lonmsg provides routines for sending messages, receiving messages, and
42: a handler to allow users to read, send, and delete messages.
43:
44: =head1 OVERVIEW
45:
46: =head2 Messaging Overview
47:
48: X<messages>LON-CAPA provides an internal messaging system similar to
49: email, but customized for LON-CAPA's usage. LON-CAPA implements its
50: own messaging system, rather then building on top of email, because of
51: the features LON-CAPA messages can offer that conventional e-mail can
52: not:
53:
54: =over 4
55:
56: =item * B<Critical messages>: A message the recipient B<must>
57: acknowlegde receipt of before they are allowed to continue using the
58: system, preventing a user from claiming they never got a message
59:
60: =item * B<Receipts>: LON-CAPA can reliably send reciepts informing the
61: sender that it has been read; again, useful for preventing students
62: from claiming they did not see a message. (While conventional e-mail
63: has some reciept support, it's sporadic, e-mail client-specific, and
64: generally the receiver can opt to not send one, making it useless in
65: this case.)
66:
67: =item * B<Context>: LON-CAPA knows about the sender, such as where
68: they are in a course. When a student mails an instructor asking for
69: help on the problem, the instructor receives not just the student's
70: question, but all submissions the student has made up to that point,
71: the user's rendering of the problem, and the complete view the student
72: saw of the resource, including discussion up to that point. Finally,
73: the instructor is reading all of this inside of LON-CAPA, not their
74: email program, so they have full access to LON-CAPA's grading
75: interface, or other features they may wish to use in response to the
76: student's query.
77:
78: =item * B<Blocking>: LON-CAPA can block display of e-mails that are
79: sent to a student during an online exam. A course coordinator or
80: instructor can set an open and close date/time for scheduled online
81: exams in a course. If a user uses the LON-CAPA internal messaging
82: system to display e-mails during the scheduled blocking event,
83: display of all e-mail sent during the blocking period will be
84: suppressed, and a message of explanation, including details of the
85: currently active blocking periods will be displayed instead. A user
86: who has a course coordinator or instructor role in a course will be
87: unaffected by any blocking periods for the course, unless the user
88: also has a student role in the course, AND has selected the student role.
89:
90: =back
91:
92: Users can ask LON-CAPA to forward messages to conventional e-mail
93: addresses on their B<PREF> screen, but generally, LON-CAPA messages
94: are much more useful than traditional email can be made to be, even
95: with HTML support.
96:
97: Right now, this document will cover just how to send a message, since
98: it is likely you will not need to programmatically read messages,
99: since lonmsg already implements that functionality.
100:
101: The routines used to package messages and unpackage messages are not
102: only used by lonmsg when creating/extracting messages for LON-CAPA's
103: internal messaging system, but also by lonnotify.pm which is available
104: for use by Domain Coordinators to broadcast standard e-mail to specified
105: users in their domain. The XML packaging used in the two cases is very
106: similar. The differences are the use of <recuser>$uname</recuser> and
107: <recdomain>$udom</recdomain> in stored internal messages, compared
108: with <recipient username="$uname:$udom">$email</recipient> in stored
109: Domain Coordinator e-mail for the storage of information about
110: recipients of the message/e-mail.
