Abstract:

Meta-information provides an additional layer of abstraction on web documents that can be used for sophisticated applications relying on the precise semantic characterization of their content. Two leading standards, RDF and Topic Maps, compete as the model through which expressing metadata. These two models are sufficiently different as to make back and forth conversion a difficult and imprecise task. In this paper, we introduce META, a set of integrated tools helping in editing, navigating and converting metadata expressed in either language.
