IEEE 1484.11.1 2004 Edition, September 23, 2004 Learning Technology—Data Model for Content Object Communication
More info
Description / Abstract:
This Standard describes a data model to support the interchange
of agreed upon data elements and their values between a
learning-related content object and a runtime service (RTS) used to
support learning management. This Standard does not specify the
means of communication between a content object and an RTS nor how
any component of a learning environment shall behave in response to
receiving data in the form specified. This Standard is based on a
related data model defined in "Computer Managed Instruction (CMI)
Guidelines For Interoperability," version 3.5 [B1], by the Aviation
Industry CBT Committee (AICC).1 To balance the need to
support existing implementations with the need to make technical
corrections and support emerging practice, this Standard
selectively includes those data elements from the CMI specification
that are commonly implemented, renames some data elements taken
from the CMI specification to clarify their intended meaning,
modifies the data types of data elements taken from the CMI
specification to reflect ISO standard data types and
internationalization requirements, removes some organizational
structures used in the CMI specification to group data elements
that are specific to the AICC community of practice and not
generally applicable, and introduces some data elements not present
in the CMI specification to correct known technical deficiencies in
data elements taken from that specification.
Purpose
There is widespread acknowledgement that the data model for content object communication defined in the AICC "Computer Managed Instruction (CMI) Guidelines for Interoperability," version 3.5 [B1], has broad applicability to systems used for learning management. The purpose of this Standard is to build consensus around, resolve ambiguities in, and correct defects in the AICC data model for the data exchanged between learning-related content objects and an RTS used to support learning management.
