The implementation of a NCL presentation engine, or formatter, is a complex task. This complexity is mainly due to the semantic distance between NCL documents, high-level declarative specifications, and the API used by the formatter to present them, in most cases low-level and imperative. The greater the distance, the greater is the complexity of this mapping and, consequently, of its implementation, which is more likely to become ineficient and bug-prone. This work presents a new NCL profile, called NCL Raw, which eliminates most of the redundancies present in EDTV | the main profile of NCL 3.0 | and, in a certain way, reduces the distance between the documents and the machine. Raw profile captures only EDTV s essential concepts, which in turn can be used to simulate the whole language defined by EDTV itself. In other words, we can use the Raw profile as a simpler intermediate language to which EDTV documents can be converted before being presented. This dissertation discusses alternative architectures for NCL converters and presents the implementation of a document converter (from EDTV to Raw).
