SCRM is international standard for sharing and reusing of learning contents as unit of SCO. But when we want to reuse this learning content by modifying a portion of it in similar knowledge domain, there is a problem that modification of original content has to be made. This paper suggests I-SCO model that enables to develop inheritable contents to solve this problem. The I-SCO model increases the reusability of contents based on SCORM by means of supporting inheritance that includes overloading and overriding. In this paper, we design and implement the I-SCO model, and execute on the runtime environment which is distributed by ADL. This experimentation shows the inheritability of contents and proves the validity of I-SCO model.
