1.1       raeburn     1: \label{Domain_Configuration_Cataloging_Courses}
                      2: LON-CAPA courses can be both self-cataloging, and also manually cataloged.
                      3: 
                      4: Self-cataloging uses the institutional course code assigned to the
                      5: course when it is first created, or when the course is modified by
                      6: a Domain Coordinator via \char`\"{}Modify a course\char`\"{}. If a
                      7: course has no institutional code it will not appear in the category:
                      8: Official courses (with institutional codes).
                      9: 
                     10: A hierarchy of categories and sub-categories can be defined which
                     11: are independent of institutional course codes. These categories might
                     12: be used to catalog courses in the domain to which the \char`\"{}official
                     13: courses\char`\"{} designation does not apply, or they might be used
                     14: to provide alternative ways of cataloging official courses.
                     15: 
                     16: Besides definition of the hierarchy of categories and sub-categories,
                     17: the \char`\"{}cataloging of courses\char`\"{} screen provides two
                     18: options to be set for the domain by a Domain Coordinator, which control:
                     19: 
                     20: \begin{itemize}
1.2       bisitz     21: \item Who may hide a course from the course/community catalog, if the course would
1.1       raeburn    22: ordinarily appear by virtue of having an institutional course code,
                     23: or having been assigned to a custom category/sub-category.
                     24: \item Who may assign a custom category/subcategory to a course
                     25: \end{itemize}
                     26: In both cases, the choice is between a Domain Coordinator and a Course
                     27: Coordinator. For the former, hiding of courses and assignment of categories
                     28: will be via \char`\"{}Modify Course\char`\"{}, while for the latter
                     29: these operations will be via \char`\"{}Modify Parameters\char`\"{}
                     30: (\char`\"{}Set Course Environment\char`\"{} option in sub-menu).
                     31: 
                     32: Definition of custom categories is by the Domain Coordinator. The
                     33: \char`\"{}Cataloging of courses\char`\"{} interface allows custom
                     34: categories and sub-categories to be defined and reordered. There is
                     35: one category listed at the top level in the hierarchy which behaves
                     36: differently to the others - the category: \char`\"{}Official courses
                     37: (with institutional codes)\char`\"{}. This is the category which is
                     38: used for self-cataloged courses: the option is to either display or
                     39: not display.
                     40: 
                     41: Although sub-categories can not be defined via this interface for
                     42: this \char`\"{}system\char`\"{} category (unlike the other \char`\"{}custom\char`\"{}
                     43: categories), customization of two routines in localenroll.pm - \&instcode\_defaults()
                     44: and \&instcode\_format() are used to automatically generate linked
1.2       bisitz     45: select boxes which will be displayed when the course/community catalog is shown
1.1       raeburn    46: to allow users to include limits to their searches for official courses.
                     47: If these routines have not been customized, the catalog for official
                     48: courses will display all courses with institutional codes, which have
                     49: not been specifically hidden.
                     50: 
                     51: When \&instcode\_format() has been customized it will populate perl
                     52: structures (hashes and arrays) which LON-CAPA will use to generate
1.2       bisitz     53: the Javascript code embedded in the course/community catalog page which is used
1.1       raeburn    54: in the functioning of the linked select boxes. The contents of the
                     55: hashes and arrays are determined from the complete list of institutional
                     56: course codes used in the domain. For example at MSU, the following
1.2       bisitz     57: linked select boxes are displayed for the official course/community catalog:
1.1       raeburn    58: Year, Semester, Department, Number.
                     59: 
1.2       bisitz     60: The course/community catalog is useful in domains where Course Coordinators
1.1       raeburn    61: have opted to allow self-enrollment in their courses. In such cases,
                     62: students can include a flag to only display courses allowing self
                     63: enrollment when they display courses from the catalog. Course Coordinators
1.2       bisitz     64: will be advised, when enabling self-enrollment, if a course is currently
                     65: unlisted in the course/community catalog (and therefore difficult for students
1.1       raeburn    66: to locate), and the action to take to rectify the reason why there
                     67: is no listing, which could be because: 
                     68: 
                     69: \begin{itemize}
                     70: \item the course is hidden 
                     71: \item the course has no institutional code 
                     72: \item the course has not been assigned to any custom categories 
1.3     ! raeburn    73: \item the course has an institutional code, but the 
        !            74: course/community catalog has been set to not display self-cataloged 
        !            75: courses.
