   33: =head1 NAME
   34: 
   35: Apache::domainprefs.pm
   36: 
   37: =head1 SYNOPSIS
   38: 
   39: Handles configuration of a LON-CAPA domain.  
   40: 
   41: This is part of the LearningOnline Network with CAPA project
   42: described at http://www.lon-capa.org.
   43: 
   44: 
   45: =head1 OVERVIEW
   46: 
   47: Each institution using LON-CAPA will typically have a single domain designated 
   48: for use by individuals affliated with the institution.  Accordingly, each domain
   49: may define a default set of logos and a color scheme which can be used to "brand"
   50: the LON-CAPA instance. In addition, an institution will typically have a language
   51: and timezone which are used for the majority of courses.
   52: 
   53: LON-CAPA provides a mechanism to display and modify these defaults, as well as a 
   54: host of other domain-wide settings which determine the types of functionality
   55: available to users and courses in the domain.
   56: 
   57: There is also a mechanism to configure cataloging of courses in the domain, and
   58: controls on the operation of automated processes which govern such things as
   59: roster updates, user directory updates and processing of course requests.
   60: 
   61: The domain coordination manual which is built dynamically on install/update of 
   62: LON-CAPA from the relevant help items provides more information about domain 
   63: configuration.
   64: 
   65: Most of the domain settings are stored in the configuration.db GDBM file which is
   66: housed on the primary library server for the domain in /home/httpd/lonUsers/$dom,
   67: where $dom is the domain.  The configuration.db stores settings in a number of 
   68: frozen hashes of hashes.  In a few cases, domain information must be uploaded to
   69: the domain as files (e.g., image files for logos etc., or plain text files for
   70: bubblesheet formats).  In this case the domainprefs.pm must be running in a user
   71: session hosted on the primary library server in the domain, as these files are 
   72: stored in author space belonging to a special $dom-domainconfig user.   
   73: 
   74: domainprefs.pm in combination with lonconfigsettings.pm will retrieve and display
   75: the current settings, and provides an interface to make modifications.
   76: 
   77: =head1 SUBROUTINES
   78: 
   79: =over
   80: 
   81: =item print_quotas()
   82: 
   83: Inputs: 4 
   84: 
   85: $dom,$settings,$rowtotal,$action.
   86: 
   87: $dom is the domain, $settings is a reference to a hash of current settings for
   88: the current context, $rowtotal is a reference to the scalar used to record the 
   89: number of rows displayed on the page, and $action is the context (either quotas 
   90: or requestcourses).
   91: 
   92: The print_quotas routine was orginally created to display/store information
   93: about default quota sizes for portfolio spaces for the different types of 
   94: institutional affiliation in the domain (e.g., Faculty, Staff, Student etc.), 
   95: but is now also used to manage availability of user tools: 
   96: i.e., blogs, aboutme page, and portfolios, and the course request tool,
   97: used by course owners to request creation of a course.
   98: 
   99: Outputs: 1
  100: 
  101: $datatable  - HTML containing form elements which allow settings to be changed. 
  102: 
  103: In the case of course requests, radio buttons are displayed for each institutional
  104: affiliate type (and also default, and _LC_adv) for each of the course types 
  105: (official, unofficial and community).  In each case the radio buttons allow the 
  106: selection of one of four values:
  107: 
  108: 0, approval, validate, autolimit=N (where N is blank, or a positive integer).
  109: which have the following effects:
  110: 
  111: 0
  112: 
  113: =over
  114: 
  115: - course requests are not allowed for this course types/affiliation
  116: 
  117: =back
  118: 
  119: approval 
  120: 
  121: =over 
  122: 
  123: - course requests must be approved by a Doman Coordinator in the 
  124: course's domain
  125: 
  126: =back
  127: 
  128: validate 
  129: 
  130: =over
  131: 
  132: - an institutional validation (e.g., check requestor is instructor
  133: of record) needs to be passed before the course will be created.  The required
  134: validation is in localenroll.pm on the primary library server for the course 
  135: domain.
  136: 
  137: =back
  138: 
  139: autolimit 
  140: 
  141: =over
  142:  
  143: - course requests will be processed autoatically up to a limit of
  144: N requests for the course type for the particular requestor.
  145: If N is undefined, there is no limit to the number of course requests
  146: which a course owner may submit and have processed automatically.
