Second generation portals tend to be constructed by means of portlets, i.e. a multi-step, user-facing application to be delivered through a Web application. For this reason, the portal developers have to face up to the problem of choosing the best portlet among a set with the same functionality in order to construct portals with a good level of quality. This requires the existence of appropriate models to assess portlet's diverse quality characteristics. One of these quality characteristics is usability. In this paper we present deeply this portlet quality characteristic by means of a software measurement ontology. The use of the ontology avoids misunderstanding the concepts since it provides a consistent (i.e. both generally agreed, with consensus, and coherent (without conflicts and contradictions)) terminology. In such a manner, the usability model presented can be easily understood and applicable by any person because each element of the model is correctly and precisely defined.
