Editec: editor gráfico de templates de composição para facilitar a autoria de aplicações NCL para TV digital interativa

Abstract

This work presents EDITEC, a graphical editor for hypermedia composite templates based on the XTemplate 3.0 language. EDITEC was designed for the creation of templates using a visual user-friendly graphical approach. It provides several options for representing iteration structures and a graphical interface for creating basic XPath expressions. The system provides a friendly environment with multiple views, giving the user a complete control of the composite template during the authoring process. Composite templates can be used in NCL programs for embedding spatio-temporal semantics into NCL contexts and making the production of interactive content easier for the Brazilian Digital TV System. The production of interactive applications is not a simple task. Authoring tools help reducing the effort required to develop those applications.
