The 3-layers of granularity model (LAG) have been introduced in A.I. Cristea and L. Calvi (2003) as a model for the adaptive behavior within adaptive hypermedia (AH). LAG is destined for authors of AH entering this process at the different levels of difficulty and flexibility: direct adaptation rules, adaptation language and adaptation strategies. The focus is on the different levels of the implied adaptation language grammars for conceptual structure and interface. We show their design, creation and implementation in MOT, an on-line adaptive hypermedia authoring system [MOT, http://wwwis.win.tue.nl/~acristea/mot.html]. We also show how the basic adaptation language can be extended by AH designers, via the adding of adaptive procedures.
