70: =item fetch_enrollment()
71:
72: connects to the institutional classlist data source,
73: reads classlist data and stores in an XML file
74: in /home/httpd/perl/tmp/
75:
76: classlist files are named as follows:
77:
78: DOMAIN_COURSE_INSTITUTIONALCODE_classlist.xml
79:
80: e.g., msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
81: where DOMAIN = msu COURSE = 43551dedcd43febmsul1
82: INSTITUTIONALCODE = fs03nop590001
83: (MSU's course naming scheme - fs03 = Fall semester 2003, nop =
84: department name, 590 = course number, 001 = section number.)
85:
86: fetch_enrollment requires three arguments -
87: $dom - DOMAIN e.g., msu
88: $affiliatesref - a reference to a hash of arrays that contains LON-CAPA
89: courses that are to be updated as keys, and institutional coursecodes
90: contributing enrollment to that LON-CAPA course as elements in each array.
91: $replyref - a reference to a hash that contains LON-CAPA courses
92: that are to be updated as keys, and the total enrollment count in all
93: affiliated sections, as determined from institutional data as hash elements.
94:
95: As an example, if fetch_enrollment is called to retrieve institutional
96: classlists for a single LON-CAPA course - 43551dedcd43febmsul1 which
97: corresponds to fs03nop590, sections 001, 601 and 602 , and the course
98: also accommodates enrollment from a crosslisted course in the ost
99: department - fs03ost580002:
100:
101: the affiliatesref would be a reference to %affiliates which would be:
102:
103: @{$affiliates{'43551dedcd43febmsul1'}} =
104: ("fs03nop590001","fs03nop590601","fs03nop590602","fs03ost580002");
105:
106: fetch_enrollment would create four files in /home/httpd/perl/tmp/.
107: msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
108: msu_43551dedcd43febmsul1_fs03nop590601_classlist.xml

110: msu_43551dedcd43febmsul1_fs03ost580002_classlist.xml
111:
112: In each file, student data would be stored in the following format

140: The <startdate> and the <enddate> are the activation date and expiration date
141: for this student's role. If they are absent, then the default access start and
142: default access end dates are used. The default access dates can be set when
143: the course is created, and can be modified using the Automated Enrollment
144: Manager, or via the 'Upload a class list','Enroll a single student' or
145: 'Modify student data' utilities in the Enrollment Manager, by checking the
146: 'make these dates the default for future enrollment' checkbox. If no default
147: dates have been set, then the tudent role will be active immediately, and will
148: remain active until the role is explicitly expired using ENRL -> Drop students.
149: If dates are to included in the XML file, they should be in the format
150: YYYY:MM:DD:HH:MM:SS (: separators required).
151:
1.44 raeburn 152: The <credits> tag need only be used if the credits earned by the students will
153: be different from the default for the course. The course default is set when the
154: course is created and can be modifed by a Domain Coordinator via "View or
1.50 raeburn 155: modify a course or community" on the DC's Main Menu screen.

159: section in the domain config screen for:
160: "Default authentication/language/timezone/portal/types"
161:
162: If no status types are defined for the domain this tag can be omitted.

170: The purpose of the %reply hash is to detect cases where the institutional

172: In such a case, the LON-CAPA course roster is left unchanged (i.e., no
173: students are expired, even if automated drops is enabled.
174:

176: could be established to the institutional data source.
177: 0 is returned if no connection could be made.

179:
180: A return of 1 is required for the calling modules to perform LON-CAPA

348:
349: Course requests will trigger this check if the process type has been set

1.46 raeburn 377: The following can be returned: process, rejected, pending, approval or

1.38 raeburn 385: (c) pending - the requestor is not the recorded instructor, but could
386: become so after administrative action at the institution. Put the
1.46 raeburn 387: request in a queue and, if an official course, check

409: menu for Course Requests. Ultimately it is called by domainprefs.pm (via:
410: lonnet -> lond -> localenroll.pm) The domain configuration menu includes
411: a table where columns are course type (official, unofficial or community)
412: and rows are institutional affiliations (e.g., Faculty, Staff, Student etc.).
413:
1.42 raeburn 414: crsreq_checks() takes three arguments: $dom, $reqtypes, $validations.
1.38 raeburn 415: $dom - the domain for which validation options are needed.

417: $validations - ref to a hash of a hash which will determine whether "validate"
418: will be one of the possible choices for each course type (outer hash key),
419: and institutional type (inner hash key).
420:
421: For example to allow validate to be a choice for official classes for Faculty,
422: req_checks would include:
423:
424: $validations{'official'}{'Faculty'} = 1;
425:
426: This routine is closely tied to validate_crsreq(). "Validate" should not be
427: a possible choice in the domain configuration menu for a particular course
428: type/institutional affiliation, unless a corresponding validation code has
429: been implemented in validate_crsreq().
430:
431: For example at MSU, official courses requested by Faculty will be validated

563: 1 means password created. In this case the calling module - Enrollment.pm

567: course coordinator (if the new user was created using the 'update roster

569: (c) a flag to indicate that the authentication method is correct - 'ok'.
570: If $authchk is not set to 'ok' then account creation and enrollment of the
571: new user will not occur.
572: (d) if a password was created it can be sent along. This is the password
573: which will be included in the e-mail sent to the new user, or made available
574: to the course owner/course coordinator if no e-mail address is provided. If
