After many years of hypertext research, the Dexter model was defined to capture the features of most existing hypertext systems in a single, formal reference model. Likewise, the AHAM model [5] (based on Dexter) describes most features that are found in adaptive hypermedia systems (ahs). In the AHA! project funded by the NLnet Foundation we are extending the simple AHA system with the condition-action rules that were introduced in AHAM. This results in a more versatile adaptation engine, with more intuitive and more powerful rules.
