Current paper presents a research in the area of e-learning interoperability, and more
concrete in assessment area. As first there is reviewed state-of-the-art in
specifications, managed by IMS consortium. Next there are discussed relations
between these specifications and rationale behind assessment specifications evolution.
Next is presented Assessment Interoperability Bus (AIB), as a skeleton for further
facilitation of presentation in assessments interoperability. As result there are present
one attempt for describing objects participating in assessment authoring and
sequencing interactions among them and assessment author. Some words of
conclusion and further works are prescribed for developing a tool based on such
defined concepts
