Subject: Re: [dita-learningspec] Design of Learning Map Topicrefs: Why No Subordinate Refs?





Just noticed this is in the current draft of the 1.2 Arch Spec, under
"Chunking"/"Examples of use":

Identification of a set of topics as a unit

   A curriculum developer wants to compose a lesson for a SCORM LMS
(Learning Management System) from a set of topics without constraining reuse
of those topics. The LMS can save and restore the learner's progress through
the lesson if the lesson is identified as a referenceable unit. The
curriculum developer defines the collection of topics with a DITA map, using
the chunk attribute to identify the learning module as a unit before
generating the SCORM manifest.

So MP was way ahead of us.

Cheers,

E.
