<description>Learning Objects are being packaged for interoperability using internationally agreed
standards such as the Sharable Content Object Reference Model (SCORM). A coursedesigner
aggregating heterogeneously created Sharable Learning Objects (SLOs) from a
repository when challenged with coarse SLOs would find a standards-based editor to be a
useful tool for re-authoring if the interoperability of an edited coarse SLO could remain intact
after the edits. Further, since many authoring applications are beginning to use XML to
define SLOs (XSLOs) it is inevitable that a repository will contain (solely) heterogeneously
authored XSLOs and as a result, we focused our research on maintaining the interoperability
of re-authored coarse XSLOs.
This paper presents research conducted to determine if a coarse XSLO could be edited in a
standards-based editor without affecting its interoperability. Initially a model for the XSLO
was developed and titled SIM. We found that if the SIM is applied during the authoring
process, it will afford protection to the interoperability of the XSLO when the XSLO is
subsequently edited in a corresponding SIM-aware DOM editor.
We describe how a DOM editor (based on the Document Object Model) can be transformed
into a SIM-aware DOM editor such that it is still standards-based. In addition, we present the
application eLearnPro, which was developed to test the interoperability of XSLOs that were
authored using the SIM, then re-authored by a SIM-aware DOM editor.</description>
