Abstract
Nowadays, interoperability of learning management systems is still not very high. The authoring tools can help transfer e-learning content between different learning management systems. However, in this context, they should be able to produce learning content that is compliant with some industry standards. One of the most widely used standards is the SCORM 1.2 release. The research addresses the extension of the functionality of the previously developed content development tool EMMA by incorporating into it the support for the subset of SCORM 1.2 requirements. The paper describes the process of the acquisition, implementation, and validation of the defined requirements. Moreover, it presents the results of the analysis of 33 SCORM authoring tools and 16 SCORM players.
