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

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
155: modify a course or community" on the DC's Main Menu screen.
156:
157: A value for <inststatus> should be the institutional status used for students,
158: and should be one of the types defined in inst_usertypes(). If no status
159: types are defined for the domain this tag can be omitted. If Autoupdate.pl
160: is enabled in your domain, updates to the institutional status set here
161: will be updated by Autoupdate.pl, should changes occur.

169: In such a case, the LON-CAPA course roster is left unchanged (i.e., no
170: students are expired, even if automated drops is enabled.
171:
172: fetch_enrollment should return a 0 or 1, depending on whether a connection
173: could be established to the institutional data source.
174: 0 is returned if no connection could be made.
175: 1 is returned if connection was successful
176:
177: A return of 1 is required for the calling modules to perform LON-CAPA

179: msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml

342: This is used to check whether a course request should be processed

344: the institution.
345:
346: Course requests will trigger this check if the process type has been set
347: to 'validate' for the course type (official, unofficial or community) and
348: the requestor's affiliation. Whether "validate" is an available option
349: in the Domain Configuration menu is controlled by auto_courserequest_checks().
350: One scenario is where the request is for an official course, in which case
351: a check could be made that the requestor is listed as instructor of
352: record for the course in the institution's course schedule/database.
353:
354: Other scenarios are possible, and the routine can be customized according
355: to whatever rules a domain wishes to implement to run validations against
356: given the data passed in to the routine.
357:
358: validate_crsreq takes six arguments -
359: (a) the LON-CAPA domain that will contain the course.
360: (b) the username:domain for the course owner.
361: (c) the course type (official, unofficial or community)

1.40 raeburn 373: (b) rejected - the requestor should never be requesting this course, reject the
1.38 raeburn 374: request permanently
375: (c) pending - the requestor is not the recorded instructor, but could
376: become so after administrative action at the institution. Put the
377: request in a queue and check localenroll:validate_instcode()
378: periodically until the status changes to "valid".

393:
394: This is used to determine whether the "validate" option should appear in the
395: possible choices for course request processing in the Domain Configuration
396: menu for Course Requests. Ultimately it is called by domainprefs.pm (via:
397: lonnet -> lond -> localenroll.pm) The domain configuration menu includes
398: a table where columns are course type (official, unofficial or community)
399: and rows are institutional affiliations (e.g., Faculty, Staff, Student etc.).
400:
1.42 raeburn 401: crsreq_checks() takes three arguments: $dom, $reqtypes, $validations.
1.38 raeburn 402: $dom - the domain for which validation options are needed.
403: $reqtypes - ref to an ARRAY of course types (i.e., official, unofficial and community.
404: $validations - ref to a hash of a hash which will determine whether "validate"
405: will be one of the possible choices for each course type (outer hash key),
406: and institutional type (inner hash key).
407:
408: For example to allow validate to be a choice for official classes for Faculty,
409: req_checks would include:
410:
411: $validations{'official'}{'Faculty'} = 1;
412:
413: This routine is closely tied to validate_crsreq(). "Validate" should not be
414: a possible choice in the domain configuration menu for a particular course
415: type/institutional affiliation, unless a corresponding validation code has
416: been implemented in validate_crsreq().
417:
418: For example at MSU, official courses requested by Faculty will be validated
419: against the official schedule of classes to check that the requestor is one
420: of the instructors of record for the course. In this case validate_crsreq()
421: includes a call to validate_instcode().
