Data about metadata: beating the Metamap into shape

Abstract

The MetaMap presents information about metadata standards, sets, and initiatives (MSSIs) in the form of a subway map. The MSSIs are represented as stations on lines having themes. Users can learn about MSSIs of interest to them by navigating around the map and clicking on points of interest to get more information about them. The map is constructed using Scalable Vector Graphics (SVG), a recommendation of the World Wide Web Consortium. Versions in number of languages are available, and more are being built; however, since funding has run out, the mapâ s future is uncertain. This paper discusses the classification of metadata and design issues surrounding representation of this in the form of a subway map. Finally, paths for development of the MetaMap are indicated.
