[edit] Overview

[edit] Podcasting In General

[edit] To Publish & Consume

The ability to create audio/video/multimedia files and distribute them over the Internet, using either a Play Now, Download, or Subscribe model, is often referred to as podcasting. The original intention behind podcasting was to publish content, usually music, and transfer the files to an individual's iPod for mobile enterntainment. Today, the term has become more generic in meaning. Podcasting refers to uploading audio or video content to a web server and providing a web page with links to Download & Play a presentation or file. In fact, some have stated that the "Pod" in Podcasting doesn't really refer to Apple's iPods, but rather is an acronym for Play On Demand.

Another typical scenario has consumers using aggregators (sometimes referred to as podcatchers) to subscribe to podcast feeds or channels and automatically receive the content for playback or transfer to mobile devices. iTunes can be considered a podcatcher, as well as dozens of other RSS feed aggregators (RSS stands for Really Simple Syndication).

A partial list of available podcatchers has been created in the Wikipedia under the term Podcatcher and has the URL of http://en.wikipedia.org/wiki/List_of_Podcatchers . Additional information about RSS feeds and aggregators can be found at the University of Utah web page about RSS News and Event Feeds. Wikipedia also contains an article about the RSS File Format.

Podcasting is about publishing content quickly. It is also about content consumers being able to transparently and seamlessly play the audio, video, images, and text that can be included in podcast files. According to Michael Geoghegan, GigaVox Media, in his presentation at the 2006 Iowa DTV Symposium, 72% of users employ the iTunes software (both Macintosh and Windows platforms) to "podcatch" content. iTunes is not required to podcatch; 22% of users simply employ standard web browsers and associated media plug-ins to gather podcast content.

Podcasting is not necessarily about downloading files and transferring them to personal mobile devices such as an iPod. In the same presentation by Michael Geoghegan, he cited that 80% of podcast video is viewed on an end user's computer, rather than being transferred to iPods for mobile viewing.

Because publishing and catching content via "podcasting" can be accomplished in numerous ways and on various computer platforms, a selection of tutorials and documentation is listed in the RESOURCES section of this page on Podcasting. As well, links to existing iTunes U implementations at various Universities are included at the end of the RESOURCES section.

[edit] Podcasting with iTunes U

In general, the availability of a very special iteration of iTunes targeted for University audiences, is known as iTunes U. According to Apple Computer,

"iTunes U uses the iTunes Store infrastructure and is specifically designed as a service for institutions to manage a broad range of audio, video, and PDF content, and make it available quickly and easily to students, instructors, staff, alumni, and, optionally, the public."

The following overview of iTunes U includes the system requirements and components that make up an iTunes U site and the steps you must take to initially create and set up a site. This information is excerpted from iTunes U documentation as provided by Apple Computer and provides one of the most concise overviews of the iTunes U service and its features. As well, the procedures to take advantage of an iTunes U service can be generalized and are similar to most other podcasting creation and publishing methods.

[edit] Apple's Executive Summary of iTunes U

(from Apple Computer) In today’s world, students, as well as instructors and staff, expect an environment that accommodates their digital lifestyle, adapts to their individual learning and teaching needs, and encourages collaboration and teamwork. To meet these expectations, Apple introduces iTunes U.

iTunes U uses the iTunes Music Store infrastructure and is specifically designed as a service for institutions to manage a broad range of audio, video, and PDF content, and make it available quickly and easily to students, instructors, staff, alumni, and, optionally, the public.

iTunes U offers an experience similar to using the iTunes Music Store. In fact, since iTunes U pages are displayed within the iTunes application itself, just like iTunes Music Store pages, navigating within iTunes U is much like navigating within the iTunes Music Store.

Using iTunes U, users can access educational content, including lectures and interviews, 24 hours a day, 7 days a week. Users can browse content and download it to their Mac computers or PCs, regardless of their location. They can then listen to and view content on their computers or transfer the content to iPod for listening or viewing on the go. Instructors and staff can easily post and change content on their own. Using the Drop Box and Shared tabs, instructors can allow students to upload their own content for review or to share with other students in the class.

[edit] System Requirements

(from Apple Computer) iTunes U fits seamlessly into your existing technologies and systems; you use your existing web-based infrastructure to provide access to your iTunes U site.

iTunes U is designed to work with any existing web authentication and authorization system your institution may be using, including LDAP, Kerberos, Shibboleth, and single sign-on systems. [iTunes U system administrators] should expect to perform some level of development and system integration work for these systems.

iTunes U requires iTunes version 6.0 or later for Mac and Windows. In order to guarantee a consistent user experience, always use the latest version of iTunes.

iTunes U works with most modern, standards-compliant browsers. Apple recommends using one of the following browsers:

Safari 2.0 or later on Mac
Firefox 1.5 or later on Mac or Windows
Internet Explorer 6.0 or later on Windows

iTunes U supports the distribution of compressed audio and video files. Apple recommends using the following formats for your iTunes U audio and video content:

Audio files (AAC, MP3) with appropriate file extensions (.m4a, .mp3)
Video files (MPEG-4, H.264) with appropriate file extensions (.mp4, .m4v, .mov). For best

results with iPod, Apple recommends using H.264.

You can also use iTunes U to distribute Portable Document Format (PDF) files.

[edit] Getting Started

(from Apple Computer) Apple creates your [institution's] initial iTunes U site using a default page design and layout, hosting all content onsite at Apple. [Customization of the initial iTunes U site is then undertaken by the site administrator, the J. Willard Marriott Library.]

[edit] Planning Your iTunes U Site

(from Apple Computer) Each iTunes U site, and its structure and content, is organized in an easy-to-use hierarchy of folders and files, or pages and objects. Your initial iTunes U site and structure is based on information [your institutuion] provided to Apple. [The site administrator] can use this structure as a starting point. However, before you start populating your iTunes U site with content, [the site administrator] should take time to further plan your site’s organization, including its structure and user access privileges.

To set up and apply authorization and access privileges properly, [the site administrator must organize] content into a structure based on the amount of content you will provide and the desired access privileges for each user. For example, you can use the following structure:

In this example, you can restrict user access to the entire site, to each Course page, or down to the individual tabs in the English Course page. Note--When you assign a user access privileges to a page or tab, the user automatically receives access privileges to the page’s or tab’s ancestors, if any exist. For example, in the diagram above, if you assign a user access privileges to the Audio tab, and its ancestors are the English Course page and the Institution Welcome page, the user automatically can access those pages, too.

To restrict user access to specific pages and tabs, [the site administrator defines] user groups and then assign[s] each group unique access privileges to the specific pages or tabs. For example, you can define the following user groups:

Site administrator

This group has the most privileges, allowing it to create new Course pages, assign ownership of Course pages to specific instructors, and manage the iTunes U site.

Instructor

This group has privileges constrained to the classes to which they are assigned, allowing it ownership for the particular class and its Course page.

Student

This group has the fewest privileges, constrained to the classes in which the students are registered, allowing the group access to the particular class and its Course page, with specific privileges defined by the instructor who owns the page.

[edit] Preparing a Course for iTunes U

(from Apple Computer) The iTunes U site is designed to provide students and instructors easy access to course content. It can also provide access to institutional information such as upcoming events, sports news, or a message from the institution president.

The instructor or course manager creates the content for the course and then uploads the content to the site on a page specific to the course. Each course has its own Course page.

A site administrator initially creates the pages for each of the courses. An instructor or course manager prepares the content (recording lectures, assignments, creating videos). Then the course manager organizes the Course page by creating tabs for the content for students to download and upload assignments and for students to share their work.

[edit] Organizing Course Content

(from Apple Computer) How a course is organized depends on the course manager’s preferences. Each Course page consists of various tabs used to organize the contents. Courses can be organized by subject matter or by media type. For example, a course covering the life and works of F. Scott Fitzgerald could have tabs by subject matter (life and works), or by type of work (novels and short stories).

Alternatively, the course could be organized by media type, for example, one tab for audio content, another tab for video content, and another tab for PDF content.

Other tabs might include a Drop Box for student assignments and a Shared tab for students to share their work with others.

[edit] Providing Links to Other Information

(from Apple Computer) In addition to tabs, course managers can add links to point students to more information. For example, the course manager could add a link to a website that discusses all the films made from F. Scott Fitzgerald’s works.

[edit] Preparing Content

(from Apple Computer) After creating the tabs, content can be uploaded into the tab. Apple recommends using an AAC format for audio or H.264 format for video for content that gets uploaded into the course tabs.

For details on file formats, see Creating Content for iPod + iTuneslocated at http://www.apple.com/support/itunes_u/ .

[edit] Podcasting Metadata in iTunes and iTunes U

(from Apple Computer) Information about information is called metadata. For example, an audio file contains audio information. The name of the person that created the file, the length of the file, title of the file, description, and so on, are examples of metadata a file might contain.

Metadata is useful for several reasons:

The iTunes and iPod user interface is built from the metadata. For example, clicking the Artist category would yield useless results if you didn’t enter information for the artist metadata.
It makes browsing and searching much more efficient and helpful to your audience. Listeners can search by the information in the Artist field, search by your groupings, or any other category.
It supports and reinforces the content. For example, in an educational context, metadata meets the needs of different learning styles.There are visual learners and those who learn better by reading text. A speech of a political leader could include the text of the speech that listeners can read as they hear the speech, and it could include a picture of the speaker so listeners can connect emotionally to the voice.

While some metadata may be entered when you publish your files to the server, it is also important to include some embedded metadata in the file itself. iTunes and many other applications can display and use this metadata for cataloging as well as search and retrieval functions. If you add metadata to file formats that support metadata in iTunes, the metadata stays with the content even if it is moved.

In iTunes, metadata appears when you select a file and choose File > Get Info. There are six panes--Summary, Info, Video, Options, Lyrics, and Artwork.

The following information includes examples of iTunes metadata categories and some ideas on how the standard set of iTunes metadata elements can be re-purposed for nonmusical and academic content.

Name: Name of an article, lecture, podcast, episode, and so on.
Artist: Author, lecturer, or source of content
Year: Year the content was published or created
Album: Name of the podcast series, lecture series, course name, or chapter name/number
Grouping: Organize content by theme (such as all lectures on Italian comedic operas as opposed to the Italian romantic operas). It might be hellpful for your media consumers to sort by grouping.
Comments: Add a brief description of your content, add a website reference, or your email address. Make notes about the content that your listener might need to know. For example: “Lecture recorded on April 15, 2006,” or, “This recording contains lectures 1 and 2.”
Genre: Broad category, for example, by subject (such as architecture), by publisher, by organization (such as a university name), or by type (such as podcast) Note: Some iTunes users create smart playlists using the Genre category to transfer content automatically to iPod.

The information under the Video tab provides the opportunity to further refine the hierarchical and episodic nature of a course or forum series.

The information under the Options tab is less about metadata and more about presentation and display preferences.

For podcasts and other content, you could include a transcript to support hearing disabled learners, a summary, a list of support resources,text for a speech, text of a poem, or other information. Note: Lyrics pane is not available for video.

Include an image for the "cover" art for your content. The image is displayed in iTunes in the Album art window when the content is selected. The image is also shown on an iPod that can display photos while the audio is being played. The poster image that is used can be harvested from anywhere within a video program.

[edit] About Metadata Substitution and Download Rules

(from Apple Computer) iTunes U allows the site administrator to control the metadata of all content distributed through your institution’s iTunes U site. By controlling the metadata, the site administrator can ensure that the metadata is used consistently for all the content. The site administrator can also specify the location where tracks are downloaded.

For example, the site administrator could specify that the Album field always contains the course title and that the Genre field always contains the institution name. The site administrator can also set up iTunes U so that all content from your institution’s iTunes U site appears in an institution playlist.

If the site administrator does specify the metadata, that metadata overwrites any information you put in the fields for the content.The site administrator can overwrite the Album, Artist, Genre, Artwork, and Comments metadata fields. To see if your site administrator has specified the metadata, upload a file to iTunes U and then download that same file. In iTunes, locate the file and see if the information in the fields has changed. If a site administrator has created a rule to download content to a specific playlist, that playlist appears in the Source view of iTunes when you download content from iTunes U.

Note--If the site administrator specifies metadata for the Comments field, instructors cannot use the Comments field to communicate with their students. Any comments the instructor or student might write about content they have uploaded will be lost.

[edit] Adding a Course Image to the Course Page

(from Apple Computer) The Course page includes an image that represents the course.The site administrator might have added a default image. You can change the default image to an image specific for the course. The image acts as an icon for the course on the Course page. A smaller version of the image appears on pages used to navigate to the course.

Note--Each track can have its own artwork metadata. The artwork is displayed in iTunes in the Now Playing window when the track is selected, or on the iPod during playback. If the site administrator specifies a rule to overwrite the Artwork metadata, the course image replaces the artwork for the track.

Use an image that is 300 x 300 pixels square and in one of the following formats

JPEG, PNG, GIF, or TIFF.

The file must have the appropriate file extension

.jpg, .jpeg, .png, .gif, .tif, or .tiff.

[edit] Podcasting

(from Apple Computer) Podcasting provides a convenient, subscription-based model for distributing course content. Podcasting makes your course content mobile, and supports anywhere, anytime learning. Students can subscribe to the course and have the content automatically downloaded as soon as it is made available by you.

Your site administrator controls whether or not podcasting is a feature available to Course pages at your institution. Since distributing content via podcasting might be a security concern at your institution, it might not be available. If podcasting is available, you can decide if you want to make the course content available via podcasting. While editing a Course page, select the Enable Podcasting checkbox. After turning podcasting on, you and the students will see a Subscribe button on the Course page. Clicking Subscribe allows them to subscribe to the selected podcast and use the podcasting features of iTunes.

[edit] iTunes U Documentation and Information

Full documentation is provided by Apple to the Site Administrator/Manager for the University's iTunes U installation. A gateway informational page is in development and will be posted mid-summer, 2007 with further information. Look to this MODwiki page for URL links.

[edit] Guidelines

[edit] iTunes U Service Agreement with the University of Utah

As of May 23, 2007, the University of Utah and Apple, Inc. co-signed the service agreement to establish an instance of iTunes U on our campus. Administrative functions, including the iTunes U branding, structure and user access privileges, are centrally managed by the J. Willard Marriott Library. Both public media items and rights-protected content can be posted. Content linked to specific University courses will need to be authenticated through a single sign-on using the University's LDAP; that implementation was readied for Fall Semester 2007.

There you will find information about the service, how it can be used, and where to get assistance.

Administrative functions, including the iTunes U branding, structure and user access privileges, are centrally managed by the J. Willard Marriott Library.

Principle contact: Caroljean Hanson; J. Willard Marriott Library; caroljean.hanson@utah.edu; 801-581-6575

Technical contact: Richard Glaser; J. Willard Marriott Library; richard@scl.utah.edu; 801-585-8016

With the establishment of an iTunes U Service Agreement between Apple and the University of Utah, the University's various departments, groups, institutes, and centers are able to post their own content with access governed by the UofU iTunes U branded interface. Individual entities throughout the University can request their own "sandbox" for media postings, still branded under the University of Utah, but identified as belonging to a particular group on campus.

iTunes UofU must be centrally managed as far as the administrative functions for site organization, including its structure and user access privileges. Content linked to specific courses will need to be authenticated through a single sign-on using the University's LDAP.

Convener, Host & Aggregator...not a Gatekeeper: The iTunes UofU manager is not judged as a gatekeeper who determines and selects the content that is posted. The manager tends to the integrity of the original service agreement with Apple and informs potential content contributors of the University's various policies and procedures that must be followed. The iTunes UofU manager is a convener, host, and aggregator, encouraging participation and establishing a trusted space in which content contributors and content consumers are directly connected to each other in a free exchange of ideas and information. The manager promotes individual department choices in what content should be posted and when. These philosophies parallel the Office of Information Technology’s strategy to embrace centralized coordination with distributed control.

In order to establish the trusted space of iTunes UofU, legal and ethical considerations must be known and communicated to all University parties and content contributors. Actual policies & procedures are being identified and drafted. The following bulleted list serves as an overview of upcoming guidelines...

[edit] Copyright Ownership and Content Distribution & Re-use

As in any other media creation and publishing effort, it is critical that, within the context of the environment a media item is to be used, all necessary permissions and re-use rights have been obtained for the content that is not the original work of the author or creator of the podcast.

Podcasting Legal Guide: An excellent guide has been created by the folks behind the Creative Commons licensing initiative (http://www.creativecommons.org). This guide is published as a wiki, is known as the Podcasting Legal Guide, and can be found at http://wiki.creativecommons.org/Podcasting_Legal_Guide. In the guide is a comprehensive review of the legal issues you may face in creating and distributing a podcast.

[edit] University Trademarks & Licensing

The University of Utah maintains an active and aggressive Trademarks & Licensing Program. Its mission "...is to protect, promote, and profit from the correct use of the University of Utah’s name and symbols. The department strives daily to ensure the public can identify with and trust the quality of any product or service bearing an official University of Utah mark."

A website for the Trademarks & Licensing Program articulates the mission, scope, procedures, and policies associated with managing the University's trademarks.

http://www.trademarks.utah.edu/

Within this site is a concise statement of the University of Utah's Policy on Trademark and Licensing:

http://www.trademarks.utah.edu/program/policies.html

The iTunes UofU policies and procedures will need to determine how these policies are best communicated in the iTunes UofU interface and the content that is posted.

[edit] University of Utah Disclaimer

The University maintains a single, consistent statement of disclaimer regarding "Content," "Health-Related Content," "Web Links," and the identification of the University's Copyright Agent. By its policies and procedures, this disclaimer must be added as a link for all web-based pages and sites that are published through the University of Utah. The iTunes UofU policies and procedures will need to determine how this disclaimer is best communicated in the iTunes UofU interface and the content that is posted.

http://www.utah.edu/disclaimer

[edit] University of Utah Privacy Statement

The University of Utah maintains a single, consistent statement regarding its privacy policies. Quoting from its web page, "The University of Utah has created this statement to demonstrate our firm commitment to your privacy. This document explains how we gather, use, and protect your information." Specific areas of interest regarding privacy are itemized, including...

We Don't Sell Your Contact Information
Statistical Logs Kept
Cookies Used to Preserve Settings
Security Programs Running
Security Precautions You Should Take
Alternate Ways to Submit Information
Other Sites Have Different Policies
Protecting Children's Privacy
Changing Your Information
Related Policies
Health Information Privacy

From the University's standpoint, under the advice of its General Counsel, no personal or sensitive data for faculty, staff, students, alumni and related communities can be posted through any content available via the iTunes U, University of Utah, service. Private data includes such things as grades, salaries, and Social Security numbers.

The iTunes UofU policies and procedures will need to determine how this privacy statement is best communicated in the iTunes UofU interface and the content that is posted.

http://www.utah.edu/privacy

[edit] Appropriate Content

Given the breadth and depth of the academic, philosophical, research, and political discourse that takes place on a University campus and through its programs and events, what is deemed appropriate or inappropriate content for posting and publication is subject to broad interpretation.

According to the University's Disclaimer...

"The University of Utah web site may contain information that is created and maintained by a variety of sources both internal and external to the University. These sites are unmoderated forums containing the personal opinions and other expressions of the persons who post the entries. The University of Utah does not control, monitor or guarantee the information contained in these sites or information contained in links to other external web sites, and does not endorse any views expressed or products or services offered therein. In no event shall the University of Utah be responsible or liable, directly or indirectly, for any damage or loss caused or alleged to be caused by or in connection with the use of or reliance on any such content, goods, or services available on or through any such site or resource."

Because Apple hosts the content posted through iTunes U, they have some general guidelines in place to govern the appropriateness of content. These are expressed through its iTunes Terms of Service.

"Objectionable Material. You understand that by using the Service, you may encounter content that may be deemed offensive, indecent, or objectionable, which content may or may not be identified as having explicit language. Nevertheless, you agree to use the Service at your sole risk and that Apple shall have no liability to you for content that may be found to be offensive, indecent, or objectionable. Content types (including genres, sub-genres and Podcast categories and sub-categories and the like) and descriptions are provided for convenience, and you acknowledge and agree that Apple does not guarantee their accuracy."

http://www.apple.com/legal/itunes/us/service.html

The iTunes UofU policies and procedures will need to determine in what manner to define the appropriateness of content that is posted.

[edit] Content Turnover & Timeliness

It is critical to understand that an iTunes U implementation is not an institutional repository or permanent archive of intellectual content, documents, and media. iTunes U is a content distribution solution that facilitates ease of publishing and simplicity in catching or consuming that content.

Because of the ceiling on server space provided by Apple Computer for an iTunes U institution (set at 500 Gigabytes--2006), the media items provided through the interface are intended to be retained on a temporary or semi-permanent basis. For example, materials related to a specific academic course would be posted for the duration of a specific semester, removed, and perhaps re-posted when the course is taught again within one or two years. Of course, on-going courses would have no reason to post, delete, and re-post content that is under continuing use. Semi-permanent media items, such as Hinckley Institute of Politics forum presentations or current galleries of art works from the Utah Museum of Fine Arts are encouraged to retain their presence through their iTunes U space. However, content that is of a more archival nature is best stored and distributed through other means available in repositories, library collections and digital asset and content management systems already in place at the University of Utah.

Nothing in this discussion precludes a department from building an interface to harvest content from their permanent collections (managed through an existing asset management system) and publishing these items to their iTunes U space for an appropriate period of time or use. The items would be deleted from iTunes U when their distribution cycle has concluded. The items can be reintroduced as time and circumstance dictate.

Interestingly, none of the existing iTunes U implementations at other higher education institutions has exceeded their space allocation at Apple Computer. During 2006, Apple doubled the allocation space per institution. Given the ever-diminishing costs of storage, it is not illogical to assume that the allocation would increase again in the near future.

[edit] Other iTunes UofU Policies & Procedures

There are likely other policies and procedures to be identified and interpreted with regard to iTunes UofU. Look to the iTunes U administrators at the J. Willard Marriott Library to research and identify these issues, providing a standard set of guidelines for those wishing to contribute content to iTunes UofU.

[edit] Universities Using iTunes U

Many higher education institutions have embraced the concept of podcasting, and have taken advantage of Apple's iTunes U opportunities. Stanford, Berkeley, Duke University, University of Michigan, and the University of Wisconsin-Madison are current iTunes U institutions. Below are listed links to these institutions' iTunes U implementations. Note that in some cases, access is restricted to student and faculty authorization; Stanford and Berkeley are examples of an institution with both private and public-facing content.
