Mobile Patrons: Better Services on the Go (For Novice)

  1. 1. Mobile Patrons: Better Services on the Go Vincci Kwong and Gary Browning Indiana University South Bend 10th Brick & Click Libraries November 5, 2010
  2. 2. Mobile Internet Usage
  3. 3. Mobile Data Applications Usage
  4. 4. Statistics for Library Website
  5. 5. Mobile Website or Mobile App? • Target audience • User experience • Technical skills • Costs
  6. 6. First Version of Library Mobile Site
  7. 7. Popular Items on Mobile Website • Library catalog • Floor map • Events • Hours • Social media info
  8. 8. IU Mobile Initiative https://m.iu.edu/miu-prd/about/index.shtml
  9. 9. Graphic Icon for Mobile
  10. 10. Schurz Library Mobile Interface http://m.library.iusb.edu
  11. 11. Statistics for Library Mobile Website
  12. 12. Mobile Site Generator • Hidden Peanuts • Molly • iPhone Application - DCPL
  13. 13. Mobile Friendly Authentication Internet Built-in Authentication Remote access to subscription databases is done through OCLC’s EZproxy Authentication and Access software.
  14. 14. Mobile Friendly Authentication Internet Built-in Authentication EZproxy does not have built-in support for mobile devices. X
  15. 15. How to make EZproxy Mobile Friendly Incorporate a mobile device detection library? http://detectmobilebrowsers.mobi/
  16. 16. EZproxy Ticket Authentication http://ezproxy.yourlib.org:2048/login? user=rdoe&ticket=a6911a5d0219f428b33e190a80818625%24c20 041222220203&url=http://www.somedb.com/ “Ticket authentication allows remote systems to short-lived URLs that EZproxy will automatically recognize as being authorized to login and permit access to a resource with no need for EZproxy to check back with the program that creates the URL.” – OCLC website
  17. 17. Sample PHP code <?php require("ezproxyticket.php"); $ezproxy = new EZproxyTicket("http://ezprox y.yourlib.org:2048", "shhhh", "someuser"); ?> <a href="<?php echo($ezproxy- >url("http://www.somedb.co m")) ?>">Some Database</a><br /> EZproxy user.txt ::Ticket TimeValid 90 MD5 shhhh Expired; Deny expired.htm /Ticket
  18. 18. EZproxy Ticket Authentication Internet Valid ticket? Generate Ticket Web Server with PHP Server with ezProxy
  19. 19. External Authentication Internet Valid ticket? authenticated? Generate ticket authentication validation service Server with ezProxyWeb Server with PHP
  20. 20. Central Authentication System (CAS) Central Authentication Service (CAS) is a login service that allows you to access multiple password-protected web systems after logging in once on a central authentication server; this is often referred to as single sign-on. http://www.jasig.org/cas
  21. 21. CAS vs IU CAS Standard CAS response – XML <cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'> <cas:authenticationSuccess> <cas:user>username</cas:user> <cas:proxyGrantingTicket>PGTIOU-84678-8a9d... </cas:proxyGrantingTicket> </cas:authenticationSuccess> </cas:serviceResponse> IU CAS response – If validation is successful, CAS sends back a two-line response with 'yes' on the first and 'username' on the second.
  22. 22. Connecting Ezproxy with IU CAS 1. Detect mobile or desktop • http://detectmobilebrowsers.mobi/ 2. Set CASSVC (service) • If detect mobile, set service to mobile 3. Check with CAS to see if already authenticated 4. If authenticated, display database; otherwise present a login screen
  23. 23. Sample Code – login.php <?php include('mobile_device_detect.php'); if(mobile_device_detect(true,true,true,true,true,true,false,false)){ header("Location: https://cas.iu.edu/cas/login? cassvc=MOBIU&casurl=https://www.domain.edu/~site/cas/casauth.php"); }else{ header("Location: https://cas.iu.edu/cas/login? cassvc=IU&casurl=https://www.domain.edu/~site/cas/casauth.php"); } ?>
  24. 24. Sample Code – casauth.php <?php session_start(); //start session if( isset($_GET['casticket']) ){ //check to see if a ticket has been passed $ticket = $_GET['casticket']; } else { $ticket = ""; }
  25. 25. Sample Code – casauth.php cont. /* * check CAS ticket authenticity and get the user's uid back * the variable $contents will have the string * "ticket '<ticket value>' not recognized" if a bad ticket * has been provided. */ $casXML = fopen("https://cas.iu.edu/cas/validate? cassvc=IU&casticket=$ticket&service=https://www.domain.edu/~site/cas/c asauth.php","r"); $contents = fread($casXML, 1024); fclose($casXML);
  26. 26. Sample Code – casauth.php cont. list($yesno, $netid) = split("n", $contents, 2); $authok = trim($yesno); $iuid = trim($netid); if ($authok == "no") { header("Location: https://www.domain.edu/~site/cas/login.php"); } else { $_SESSION['auth'] = $iuid; header("Location: https://www.domain.edu/~site/cas/success.php"); } ?>
  27. 27. A Better Idea – Can IU Mobile do it? IU Mobile is already connected to IU CAS Need ability to • Check if authenticated • Display alternative information if not • Restrict to campus level
  28. 28. Yes, IU Mobile Can do it! <authenticated> <list-item> <link type="xml" xml="http://it.iusb.edu/demo2.php" title="Subscription Databases" /> </list-item> </authenticated> <not-authenticated> <list-item> <link type="xml" xml="http://library.iusb.edu/miuxml/oopsSubscribed.xml" title="Subscription Databases" /> </list-item> </not-authenticated>
  29. 29. Authenticated vs. Not-Authenticated
  30. 30. Sample Restriction to South Bend <list-item> <authenticated> <if permission="southbend"> <link type="external" url="<?php echo($ezproxy- >url("http://vnweb.hwwilsonweb.com/mobile/jumpstart.jhtml")) ?>" title="HW Wilson" /> </if> </authenticated> </list-item>

  32. 32. Computer Availability Mobile Webpage http://m.iusb.edu
  33. 33. System Requirements Computer Availability • Web Server such as Apache or IIS • PHP • Database such as MySQL • Ability to run login and logout scripts
  34. 34. How It Works Internet Workstations Web Server with PHP MySQL Server Active Directory Server www.iusb.edu/~labseats
  35. 35. For Mobile, Output Data as XML <seats> <?php foreach ($regions as $region) { $region_id = $region['region_id']; $region_display_name = $region['display_name']; $region_location = $region['location']; $region_mac_status_counts = get_status_counts_for_region($region_id, 'Mac'); $region_pc_status_counts = get_status_counts_for_region($region_id, 'PC'); $total_idle_mac_computers = $region_mac_status_counts['idle']; $total_busy_mac_computers = $region_mac_status_counts['busy']; $total_idle_pc_computers = $region_pc_status_counts['idle']; $total_busy_pc_computers = $region_pc_status_counts['busy']; $total_idle_computers = $total_idle_mac_computers + $total_idle_pc_computers; $total_online_computers = $total_idle_computers + $total_busy_computers; print "<seat lab="$region_building $region_location" building="$region_display_name" availability="$total_idle_computers/ $total_online_computers" campus=" SB" /> n”; } ?> </seats>
  36. 36. Mobile Output Internet Web Server with PHP MySQL Server IU Mobile Server
