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
109: msu_43551dedcd43febmsul1_fs03nop590602_classlist.xml
110: msu_43551dedcd43febmsul1_fs03ost580002_classlist.xml
111:

139:
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
1.60 ! raeburn 147: dates have been set, then the student role will be active immediately, and will
1.32 jms 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.
1.44 raeburn 156:
157: A value for <inststatus> should be the institutional status used for students,
1.50 raeburn 158: and should be one of the types defined in the "Institutional user types"
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.

169:
170: The purpose of the %reply hash is to detect cases where the institutional
171: enrollment is 0 (most likely due to a problem with the data source).
172: In such a case, the LON-CAPA course roster is left unchanged (i.e., no

174:
175: fetch_enrollment should return a 0 or 1, depending on whether a connection
176: could be established to the institutional data source.
177: 0 is returned if no connection could be made.
178: 1 is returned if connection was successful
179:
180: A return of 1 is required for the calling modules to perform LON-CAPA

182: msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
