instructional media + magic What is Aggregated Layout? The experience constructed for the end user by the implementers/administrators of the portal combined with the end user's customized content A system for constructing, managing, and administering grouped content, such that the presence and level of visibility of this content is guaranteed to appear in a users layout A system to allow users to self select grouped content to appear in their layout

instructional media + magic Aggregation of content (Pushed) A users layout being constructed from pre-defined fragments

instructional media + magic Subscribable Groupings (Pulled) Health & Legal Services Column Tab by Faculty and course Departmental Calendar and Events Column User adding content that has been grouped by content administrators

instructional media + magic Some terms… Pushed Content The prearranged incorporation and updating of content in a user's uPortal Layout Pulled Content Self selected incorporation of content (including content fragments) into a users personal layout Propagate Spread or extend to users of the system

instructional media + magic Why Aggregated Layouts? To allow the construction of groupings of content (Layout Fragments) To allow modification to Layout Fragments that can be either propagated to the subscribed users of that content, or pushed to a specified set of users To allow the control of Layout Fragments Where do the fragments appear in the layout What restrictions are placed on the manipulation of the content by the user, etc… To provide access control Who can manage fragments, who can author them, who can subscribe to them

instructional media + magic Some more terms… User Layout An XML document representing the abstract structure of the content to be presented to a user Layout Fragment An XML fragment representing a grouping of content Fragment attachment point The node in the User Layout where a Layout Fragment is attached Restriction (examples) Depth greater than one (in a tab/column layout this would ensure that the node would not be a tab) Parent priority > 12 (sets the level of visibility)

instructional media + magic Some more terms… CFA's Content Fragment Administrators - Groups assigned permission to create content fragments CFA Modifications Modifications made to the fragment that is propagated to all of the users who have that fragment Personal Modifications Modifications made by the end user that only affect their own personal layout

instructional media + magic Process Overview Permissions assignment Über Administrator creates Content Fragment Administrators (CFA's) by assigning this right to a group Über Administrator assigns Priority Domains to CFA's Fragment Construction CFA's construct fragments and assign priority ranges to the content on each fragment CFA's decide which groups to push content to, and which groups will be allowed to pull content into their layout Layout Assembly Business rules are applied to assemble layouts for each end user Layout Management Users manage layouts according to assigned restrictions

instructional media + magic Process Illustration… Assume: The portal has been implemented at the top level by the University of Santa Maria Sally Smith is the Über Administrator Sally creates the following groups: Chancellors Office, Department, Faculty, Teachers Assistant, All Users Sally assigns rights to each of the groups, except "All Users", to become Content Fragment Administrators Sally assigns a priority domain for each group Bob is the end user

instructional media + magic The Path to the User… Bob University of Santa Maria Chemistry DepartmentBiology Department Jill Jones CHEM 113 Jon Deats BIO 180 Jan Tanner BIO 211 Sam Kandu BIO 224 Sally Smith

instructional media + magic Permissions Assignment Sally must decide on: The groups to create to be given Content Fragment Administrator rights The priority domains to apply to each group A permission scheme/control level High: Only Content Fragment Administrators are allowed to modify fragments. Users cannot modify content of fragments. Medium: CFA's and users are allowed to modify content, but users may only make modifications within the scope of the fragment. Low: CFA's and users are allowed to make unlimited changes within the scope of the restrictions placed on individual elements of content.

instructional media + magic Fragment Construction Jan Tanner now has her Content Fragment Administrator privileges and she wants to start constructing fragments.

instructional media + magic Fragment Construction After selecting a fragment type, she adds content and sets restrictions

instructional media + magic Fragment Construction Priority range determines the mobility of the content, and priority value (a number calculated by Aggregated Layouts) is used to determine the position of content in the layout Layout Fragment User Layout 5320 Priority range= 0-4 Priority value= 3

instructional media + magic Some more terms… Unremovable A restriction placed on an element of content (such as a channel or column or tab) such that the content cannot be deleted from the layout. This restriction does not limit movement of content. Immutable A restriction placed on an element of content (such as a channel or column or tab) such that the content cannot be moved within the layout. Hidden A restriction placed on an element of content (such as a channel or column or tab) such that the content is not visible within the layout.

instructional media + magic Fragment Construction Controls

instructional media + magic Fragment Subscription If a user is a member of a group allowed to subscribe to a fragment, then that fragment will appear during user preferences - subscription

instructional media + magic Technical Approach Define a system of restrictions on the layout nodes Implement node operations (Move, Add, Delete, Update) Implement layout assembly operations A very complex recursive process Integrate user preferences as a mode of the Structure and Theme transformations New workflow – users choose content then place it based on restrictions Users not allowed to violate restrictions based on new workflow

instructional media + magic Node Operations Move node Check restrictions on old parent node Immutable Check restrictions on new parent node Immutable Child related restrictions Check restrictions on the node being moved Depth Parent related restrictions Priority (for sibling ordering) Check depth restrictions on the descendants of the node being moved (if there are any) Move the node

instructional media + magic Node Operations Delete node Check restrictions on parent node Immutable Check restrictions on the node being deleted Unremovable Delete the node

instructional media + magic Node Operations Update node Check restrictions on current node Immutable is false Check restrictions on the parent Child related restrictions Check restrictions on the parent Parent related restrictions Check restrictions on the siblings Reorder based on the priority Update the node

instructional media + magic Layout Assembly Determine which fragments should be pushed to the user Perform node operations (add,move) for layout assembly Use “Add” operation to insert all fragments into the layout Use “Move” operation to restore local modifications of the fragments Resolve conflicts arising from restriction checks Example CFA reduced allowed priority range of the “library tab” and user’s tabs can no longer be moved in front of it

instructional media + magic Current Channel Subscribe Process 1. Choose the placement for a new channel. 2. Browse content by category 3. Browse content by name. 4. Add the new channel.

instructional media + magic The New Content Manager Opposite of the current method, adding new content starts with "what the user wants to add" instead of "where it will be positioned".

instructional media + magic The New Content Manager Metadata about the content helps the user to find channels or fragments to which they want to subscribe. Subscription parameters can be presented to the user (Language, Zip Code, etc)

instructional media + magic The New Content Manager Fragments are just content with multiple items, so they are treated the same as a channel by the content manager.

Possibilities for Enhancement

instructional media + magic Issues, Dilemmas, Ambiguities What happens when a user moves content into a fragment that is subsequently deleted? What happens when a user rearranges content on a fragment in their personal layout, then the fragment owner subsequently adds, deletes, or rearranges content? What happens when a user moves content out of a fragment into their personal content area, then that fragment is subsequently deleted?
