Abstract

Authoring tools for hypermedia languages usually provide visual abstractions, which hide the source code from the author aiming to simplify and accelerate the development process. Among other drawbacks, these abstractions modify or even break the communication process between the author and the language designer, since these languages were designed to be readable and understandable by its target audience. This paper presents a textual approach to hypermedia authoring that does not have these inconveniences, but rather uses typographical accessories, such as program visualization, hypertextual navigation, and semi-automatic error correction. The proposed approach exploits concepts known to the author and does not imply in extra cognitive overload. A use case is presented, namely the NCL Eclipse authoring environment, for Nested Context Language, the Brazilian Digital TV and ITU-T standard.
