43. Non-transitory machine readable media that stores executable instructions, which, when executed by the one or more processing devices, are configured to cause the one or more processing devices to perform operations comprising: providing for display on a terminal a learning content input user interface configured to receive learning content; receiving learning content via the learning content input user interface and storing the received learning content in machine readable memory; providing for display on the terminal a framework user interface configured to receive a framework definition, wherein the framework definition defines an order of presentation to a learner with respect to learning content; receiving, independently of the received learning content, a framework definition via the framework user interface and storing the received framework definition in machine readable memory, wherein the framework definition specifies a presentation flow; receiving from the user a publishing instruction via a publishing user interface; at least partly in response to the received publishing instruction, accessing from machine readable memory the received learning content, the received framework definition, a received style set definition, and a received protocol selection, wherein the received style set definition is received via a style set user interface that enables the user to select from a plurality of protocols, including at least a version of HTML and a non-HTML protocol, which protocol is to be used in packaging rendered merged learning content and framework definition; merging the received learning content and the received framework definition; rendering the merged the received learning content and the received framework definition in accordance with the received style set definition; and packaging the rendered merged learning content and framework definition in accordance with the selected protocol to provide a published learning document.
