NCM 3.1: A conceptual model for hyperknowledge document engineering
Most of multimedia documents available today are agnostic to data semantics and their specification language offer little to ease authoring and mechanisms to their players so they can retrieve and present meaningful content to improve user experience. In this paper, we present the main entities of the version 3.1 of the Nested Context Model (NCM), which concentrate efforts at integrating support for enriched knowledge description to the model. This extension enables the specification of relationships between knowledge descriptions in the traditional hypermedia way, composing what we call hyperknowledge in this paper. NCM previous version (NCM 3.0) is a conceptual model for hypermedia document engineering. NCL (Nested Context Language), which is part of international standards and ITU recommendations, is an XML application language that was engineered according to NCM 3.0 definitions. The extensions discussed in this paper contribute not only for advances in the NCL specifications, but mainly as a conceptual model for hyperknowledge document engineering.
