   34: =head1 NAME
   35: 
   36: Apache::domainprefs.pm
   37: 
   38: =head1 SYNOPSIS
   39: 
   40: Handles configuration of a LON-CAPA domain.  
   41: 
   42: This is part of the LearningOnline Network with CAPA project
   43: described at http://www.lon-capa.org.
   44: 
   45: 
   46: =head1 OVERVIEW
   47: 
   48: Each institution using LON-CAPA will typically have a single domain designated 
   49: for use by individuals affiliated with the institution.  Accordingly, each domain
   50: may define a default set of logos and a color scheme which can be used to "brand"
   51: the LON-CAPA instance. In addition, an institution will typically have a language
   52: and timezone which are used for the majority of courses.
   53: 
   54: LON-CAPA provides a mechanism to display and modify these defaults, as well as a 
   55: host of other domain-wide settings which determine the types of functionality
   56: available to users and courses in the domain.
   57: 
   58: There is also a mechanism to configure cataloging of courses in the domain, and
   59: controls on the operation of automated processes which govern such things as
   60: roster updates, user directory updates and processing of course requests.
   61: 
   62: The domain coordination manual which is built dynamically on install/update of 
   63: LON-CAPA from the relevant help items provides more information about domain 
   64: configuration.
   65: 
   66: Most of the domain settings are stored in the configuration.db GDBM file which is
   67: housed on the primary library server for the domain in /home/httpd/lonUsers/$dom,
   68: where $dom is the domain.  The configuration.db stores settings in a number of 
   69: frozen hashes of hashes.  In a few cases, domain information must be uploaded to
   70: the domain as files (e.g., image files for logos etc., or plain text files for
   71: bubblesheet formats).  In this case the domainprefs.pm must be running in a user
   72: session hosted on the primary library server in the domain, as these files are 
   73: stored in author space belonging to a special $dom-domainconfig user.   
   74: 
   75: domainprefs.pm in combination with lonconfigsettings.pm will retrieve and display
   76: the current settings, and provides an interface to make modifications.
   77: 
   78: =head1 SUBROUTINES
   79: 
   80: =over
   81: 
   82: =item print_quotas()
   83: 
   84: Inputs: 4 
   85: 
   86: $dom,$settings,$rowtotal,$action.
   87: 
   88: $dom is the domain, $settings is a reference to a hash of current settings for
   89: the current context, $rowtotal is a reference to the scalar used to record the 
   90: number of rows displayed on the page, and $action is the context (quotas, 
   91: requestcourses or requestauthor).
   92: 
   93: The print_quotas routine was orginally created to display/store information
   94: about default quota sizes for portfolio spaces for the different types of 
   95: institutional affiliation in the domain (e.g., Faculty, Staff, Student etc.), 
   96: but is now also used to manage availability of user tools: 
   97: i.e., blogs, aboutme page, and portfolios, and the course request tool,
   98: used by course owners to request creation of a course, and to display/store
   99: default quota sizes for Authoring Spaces.
  100: 
  101: Outputs: 1
  102: 
  103: $datatable  - HTML containing form elements which allow settings to be changed. 
  104: 
  105: In the case of course requests, radio buttons are displayed for each institutional
  106: affiliate type (and also default, and _LC_adv) for each of the course types 
  107: (official, unofficial, community, and textbook).  In each case the radio buttons 
  108: allow the selection of one of four values:
  109: 
  110: 0, approval, validate, autolimit=N (where N is blank, or a positive integer).
  111: which have the following effects:
  112: 
  113: 0
  114: 
  115: =over
  116: 
  117: - course requests are not allowed for this course types/affiliation

  120: 
  121: approval 
  122: 
  123: =over 
  124: 
  125: - course requests must be approved by a Doman Coordinator in the 
  126: course's domain
  127: 
  128: =back
  129: 
  130: validate 
  131: 
  132: =over
  133: 
  134: - an institutional validation (e.g., check requestor is instructor
  135: of record) needs to be passed before the course will be created.  The required
  136: validation is in localenroll.pm on the primary library server for the course 
  137: domain.
  138: 
  139: =back
  140: 
  141: autolimit 
  142: 
  143: =over
  144:  
  145: - course requests will be processed automatically up to a limit of
  146: N requests for the course type for the particular requestor.
  147: If N is undefined, there is no limit to the number of course requests
  148: which a course owner may submit and have processed automatically.
