CanCore and SCORM Compared: DRAFT (Last updated: July 3, 2001)

The relationship between CanCore and the Sharable Content Object Reference Model (SCORM) is not one that can be captured through a simple one-to-one comparison. SCORM, in its own words, "is a reference model that references a set of interrelated technical specifications and guidelines designed to meet the [Department of Defence's] high level requirements for Web-based learning content" (SCORM Version 1.1). CanCore, on the other hand, references only one standard --the Learning Object Metadata standard-- to meet the needs of educators and educational technologists in Canada and elsewhere. (The additional technical specifications referenced by SCORM include the IMS Content Packaging Specification, and the AICC [Aviation Industry CBT Committee] CMI Data Model and the AICC CM1001 Interoperability Guidelines.) Cancore and SCORM are related and thus can be compared only in terms of their use of the Learning Object Metadata standard. This relationship of SCORM and CanCore can be schematized in the Venn diagram, below.

Diagram 1: CanCore shares with SCORM only one of the many areas that the latter attempts to address. The small part of CanCore that lies outside of SCORM would be represented, for example, by the refinements to the educational elements and vocabularies that CanCore is undertaking.

SCORM provides three listings of LOM elements seen as core --or rather, as "mandatory" versus "optional". Each of the three listings is provided for a particular level of content aggregation identified by SCORM: "Raw Media", "Content" and "Course". Only the "Raw Media" level is used as the basis of comparison in this document. SCORM defines "Raw Media" content as "Assets such as illustrations, documents, or media streams". It further defines "assets" as "electronic representations of media, text, images, web pages, assessment objects or other pieces of data that can be delivered by a Web client." It is precisely with such objects that projects affiliated with CanCore have been concerned.

On these terms, SCORM and CanCore are fully compatible. All 11 elements that SCORM identifies as mandatory for Raw Media are also identified as "core" in the CanCore Application Profile.

The individual CanCore elements and their status for the "Raw Media" level in SCORM are listed below.
