Media in MyUCDavis are associated with questions only, i.e., do not belong to answers or feedback fields. This relationship is illustrated in the database schema shown below.
Quiz Builder Media Usage
Faculty use single or multiple images associated with a question for identification of objects or concepts. For example, an instructor in Veterinary Medicine might use multiple radiograph images along with a downloadable PDF file with those images imbedded to test student diagnostic abilities. A music instructor might use images to ask students to identify musicians, musical scores or notations. Chemistry instructors use images to display chemical formulas and biota for students to identify. An instructor might also ask a student to download a .doc, a .pdf or some other type of non-media file as part of a quiz.

Adding images and files to Samigo requires more steps is more complex than in Quiz Builder, but allows more flexibility in layout.
Images are generally stored in Resources of the course or related project worksite. A reference link is generated in a question by clicking on the file to generate a new window, using Copy Shortcut or getting the URL from Revise Properties. selecting the image icon and adding in the image url. If multiple images will be added to the a quiz, it is easy to open Resources in a new window to access to link information and quizzes at the same time.
Add a .gif, .jpg, .jpeg, or .bmp image by typing text into the HTML Editor text area and then select the location in the text where the image will appear.
Select the image icon from the text editor and a new Insert Image window will pop open.
Images can be placed before, within or after text which , allowing more display control than in Quiz Builder. Multiple images can be added by repeating these actions. Images can be placed in any text area field, including answers and feedback.
| Note |

The image source reference with this method requires that the file reside in Resources. Once an image URL is generated in Resources, the URL can be used in multiple questions or quizzes. Changing the graphic in Resources, even if the new file has a different name, will replace the image in all URL references and the new image will be renamed with the original file's name. |
When a quiz with images referenced to Resources is exported and then imported to another course or site, the path reference is retained and the images are accessible from the new course. Because only the path, but not the actual image is imported, those files associated with quizzes in Quiz Builder would need to be moved separately into Resources, and then referenced within the quiz by their new URL. Other types of files can also be linked to quizzes as links. Documents, PDF files, and other types of course materials can be referenced in the following manner: type text in any HTML Editor text area, highlight the text, and then select the link icon. Paste in the URL reference and optional title and target.
Images and documents outside of Sakai can be linked in this manneralso, as long as the URL is properly formed and the outside location is publicly accessible. For most non-media files, it is best to set the target to "_blank" to open it in a new window. The student will need to either open or save the file. Audio and other media files can be accessed successfully through this method.
Samigo v2.3 adds the ability to add an attachment to a question.

Jira Story Card Description
- for faculty to download multiple media files associated with a quiz, question pool or collection.
- Provide identification information specifying which media file(s) are associated with each question that is being exported.
- Include question title, media file name and question text in the identification information.
- Rename image files from their AFS storage name to their original file name as recorded in the myucdavis database, if possible.
- If image files are renamed, deal with name collisions in an intuitive, documented manner.
GUI Review
Media export is tied into the Quiz Builder export of quiz, collection or question pool, so the information and download are located on the export screen. The text associated with the export function is shown below.
If the user is exporting media as part of a quiz, the information lists the section and question number with which it is related. If the question exists in a pool or collection, there is no associated question number (or there will not be after import into Samigo) so the files are simply listed in the order that they are pulled from the database.
For graphic files, such as .gif, .jpg, or .bmp, the user can click to view and/or save the graphic individually. The user is provided with a download button which displays the filename as "media_quiz#.zip" where # is the id of the quiz or "media_for_kname.zip" where kname is the user's Kerberos name for collection or question pool media.
A ReadMe.txt file is included in each media download indicating the filename, question name, original (user's) filename, and question text. Because the media file is renamed for storage on upload to Quiz Builder, the information is here to assist the user in identifying their content and/or to allow them to rename their files back to the original, descriptive name. The question name will not be imported into Samigo.
Code Functionality
Currently, the MyUCDavis cms runs on ColdFusion MX 6 with an Oracle database. New code for exporting question media in a zip file will use the existing environment and will include ColdFusion code, CF components, and JavaScript. The export file generated via download will be Samigo-compliant XML.
Code modifications to 2 existing files and 1 new file in the directory 'login/CourseManagement/quiz/' are required.
The addition of the component zip.cfc in the root directory level 'login' is also required.
File Name | Proposed Addition/Modification |
|---|---|
qz_quiz_exportfiles.cfm | Calls function to pull information associated with the media files for a quiz, aan entire question pool, or a collection. Calls function to generate a ReadMe.txt message. Calls zip function to generate a zip folder and populates it with the media and ReadMe files. Generates a downloadable zip file screen. |
login/zip.cfc | This imported component is setup in the main cms directory so that it can be access globally. It's Java-based and contains the functions which generate the zip folder and copied files into it. |
qz_quiz_exportxml.cfm | Includes the download link for the user to generate their media files into a zip file. |
qz_quiz_exportxml.cfc | Includes query calls which pull the requested media files and provide user information about those files. |
Code Review
Brian Donnelly, or another qualified member of the MyUCDavis team, will perform code review on these files.

Jira Story Card Description
MyUCDavis Quiz Builder users have associated various media, including graphics, .doc and .pdf files with their questions.
These media are displayed with the question, but they are not built into the question text. Once faculty have uploaded media, they can be deleted from the question, but the files remain on the server and cannot be accessed by faculty.
It is desirable that faculty have a method of retrieving these files for review and/or import into Resources as the first step in adding the media to assessments or question pool questions in Tests & Quizzes.In addition to just accessing the files there should be a way to identify
Successful outcome will be measured by these criteria:
1) Faculty are given a method of retrieving Quiz Builder media files on a per quiz, question pool and collection basis.
2) Identification information specifying which media file(s) are associated with each question that is being exported. If there is a way to bundle the media files together with an export of the questions that would also be desirable. A text file could be included in the zip file of the media that could document this relationship possibly including a
3) Identification includes question title, media file names and even question text all together.
If the image files could be 4) Image files renamed before zipping to their original names (as recorded in the myucdavis database) this would be highly desireable. This would not obviate the need for the text file because there could be name collisions and the text file could document how a filenname is overridden in this case.An expansion of this idea would be to implement a process that would do a MyUCDavis export and take a user to an assessment import and/or question pool import page on SmartSite. This would presumably build on something like Respondus's ability to use content information to relate media to questions. A down-the-road issue that we need to keep track of, if possible.
5) If image files are renamed, deal with name collisions in an intuitive, documented manner.
