A Semantic Approach for Implementing Metadata on the World Wide Web.

Several current proposals about metadata maintain they make use of a true ‘semantic’ approach in the description of the essential characteristics of the original documents. In reality, they are largely based on the use of some ‘external’, ‘physical’ features, and address only the ‘external identification framework’ of these documents, and not their real ‘meaning’. In this paper, we describe some of the main data structures proper to NKRL (Narrative Knowledge Representation Language), a language expressly designed for representing, in a standardised way (metadata), the semantic content (the ‘meaning’) of complex multimedia documents.
