A method to generate a role-based user interface to be presented to a user includes processing a security-relevant portion of user interface code associated with an application, determining a permission by processing application role information pertaining to the user and security policy information, wherein the security policy information is distinct from the user interface code, and associated with the security-relevant portion of the user interface code and with permissions relating to the application, and generating the role-based user interface associated with the application to selectively include a user interface element based upon the determined permission.

Method and system for authorizing user interfaces

An embodiment includes a method that includes receiving, into a cache server, from a client, a request for content from a content server. The request for content includes one or more fields. The method also includes mapping the request for content into a new request for content that is without the one or more fields. The method includes performing a lookup into a cache list of the cache server based on the new request for content.

Mapping of a content request for a cache server

A learning system, method, and data structure provides collaborative activities between learners. The system includes an interface to receive a learning strategy selected by a learner. A content management system stores content and one or more collaboration elements associated with a course. A learning management system determines the learning content and the one or more collaboration elements to present to the learner based on the selected learning strategy. The learner participates using the collaboration element at a time of the learner's choosing while taking the course. The collaboration activity may be based on one or more collaboration scenarios including a brainstorming activity, a cooperative text processing activity, an explanation discourse activity, an answer-to-tutor activity, and a pro-contra dispute. The collaboration element may be provided as an intentional point of collaboration.

Instructional architecture for collaborative e-learning

A course editor includes an input to accept author commands. An interface processes and displays the author commands to facilitate the creation of a course. The interface may include a workspace to display and assemble the structural elements into the course. The workspace may include a menu of structural elements that may be added to the course. The workspace is configured to display a structural element in response to an author command selecting the structural element from the menu. The structural elements may be a sub-course, a learning unit, and/or a knowledge item.

E-learning course editor

An e-learning course may include a number of structural elements that are aggregated into one or more levels. Each higher level may refer to any instance of a lower level. The structural elements include a course, a sub-course, a learning unit, or a knowledge item. The structural elements may include metadata. The structural elements also may include relations between structural elements. The course and its structural elements do not enforce any sequence of structural elements that the learner may use to traverse the course. In addition, the structural elements may be reused and reassembled to form different courses. A content repository is configured to store course data and its structural elements. A content player is configured to access the stored course data and assemble the structural elements.

E-learning course structure

A learning system, method, and data structure provides collaborative activities between learners. The system includes an interface to receive a learning strategy selected by a learner. A content management system stores one or more structural elements associated with a course. A learning management system determines the learning content and the one or more structural elements to present to the learner based on the selected learning strategy.

Structural elements for a collaborative e-learning system

A learning system, method, and software generate a navigation path through a course based on a learning strategy. The course may be navigated by receiving graphs corresponding to the course, applying the learning strategy to the graphs, and generating a navigation path through the course for the learner based on the applied strategy. The navigation path may be used to suggest content from the course for presentation to a learner.
