Distributed learning systems are now beginning to explore the edges of their currently constrained world. Recent efforts have begun to investigate how inter-operating distributed e-learning applications can include formats previously excluded by their proprietary development and delivery environments and by the limitations of their architecture. ADL, focused first on an effort to overcome the limitation of proprietary formats, resulting in the introduction of SCORM and (soon) CORDRA. However, SCORM conformance seemed like a stifling limitation to instructional developers accustomed to using more powerful instructional designs than SCORM 1.2 supports. However, given the new structures available within the SCORM 2004 specification as well as new architectures combining SCORM with other platforms, new instructional possibilities are wide open. IAI has been exploring these capabilities, especially with respect to combining instruction conforming to SCORM with simulation conforming to the HLA (High Level Architecture) standard for simulation. Some details of this work can be found in Haynes, Marshall, Manikonda and Maloor (2004).
