LON-CAPA implements its 49: own messaging system, rather then building on top of email, because of 50: the features LON-CAPA messages can offer that conventional e-mail can 51: not: 52: 53: =over 4 54: 55: =item * B<Critical messages>: A message the recipient B<must> 56: acknowlegde receipt of before they are allowed to continue using the 57: system, preventing a user from claiming they never got a message 58: 59: =item * B<Receipts>: LON-CAPA can reliably send reciepts informing the 60: sender that it has been read; again, useful for preventing students 61: from claiming they did not see a message. (While conventional e-mail 62: has some reciept support, it's sporadic, e-mail client-specific, and 63: generally the receiver can opt to not send one, making it useless in 64: this case.) 65: 66: =item * B<Context>: LON-CAPA knows about the sender, such as where 67: they are in a course. When a student mails an instructor asking for 68: help on the problem, the instructor receives not just the student's 69: question, but all submissions the student has made up to that point, 70: the user's rendering of the problem, and the complete view the student 71: saw of the resource, including discussion up to that point. Finally, 72: the instructor is reading all of this inside of LON-CAPA, not their 73: email program, so they have full access to LON-CAPA's grading 74: interface, or other features they may wish to use in response to the 75: student's query. 76: 77: =item * B<Blocking>: LON-CAPA can block selected communication 78: features for students during an online exam. A course coordinator or 79: instructor can set an open and close date/time for scheduled online 80: exams in a course. If a user uses the LON-CAPA internal messaging 81: system to display e-mails during the scheduled blocking event, 82: display of all e-mail sent during the blocking period will be 83: suppressed, and a message of explanation, including details of the 84: currently active blocking periods will be displayed instead. A user 85: who has a course coordinator or instructor role in a course will be 86: unaffected by any blocking periods for the course, unless the user 87: also has a student role in the course, AND has selected the student role. 88: 89: =back 90: 91: Users can ask LON-CAPA to forward messages to conventional e-mail 92: addresses on their B<PREF> screen, but generally, LON-CAPA messages 93: are much more useful than traditional email can be made to be, even 94: with HTML support. 95: 96: Right now, this document will cover just how to send a message, since 97: it is likely you will not need to programmatically read messages, 98: since lonmsg already implements that functionality. 99: 100: The routines used to package messages and unpackage messages are not 101: only used by lonmsg when creating/extracting messages for LON-CAPA's 102: internal messaging system, but also by lonnotify.pm which is available 103: for use by Domain Coordinators to broadcast standard e-mail to specified 104: users in their domain. The XML packaging used in the two cases is very 105: similar. The differences are the use of <recuser>$uname</recuser> and 106: <recdomain>$udom</recdomain> in stored internal messages, compared 107: with <recipient username="$uname:$udom">$email</recipient> in stored 108: Domain Coordinator e-mail for the storage of information about 109: recipients of the message/e-mail. 110: 111: =head1 FUNCTIONS 112: 113: =over 4 114: 115: =cut 116: 117: use strict;
