Abstract

This paper presents the XTemplate 3.0 language as a solution for defining composite templates to NCL 3.0 documents. Hypermedia composite templates define nodes and links structures that can be reused in different NCL 3.0 document contexts, facilitating the authoring of hypermedia documents used in the Brazilian digital TV system interactive content creation. The XTemplate 3.0 language specification was made using a modular approach in XML Schema according to the W3C standard. With this modular approach, the specification becomes simpler to maintain and more flexible to implement, besides the possibility to create XTemplate 3.0 profiles. XTemplate 3.0 extends the previous XTemplate versions, incorporating new features to the language.
