Structured graph format: XML metadata for describing Web site structure

To improve searching, filtering and processing of information on the Web, a common effort is made in the direction of Metadata, defined as “machine understandable information about Web resources or other things”. In particular, the eXtensible Markup Language (XML) aims at providing a common syntax to emerging Metadata formats. With this idea, we propose the Structured Graph Format (SGF), an XML compliant markup language based on structured graphs, for capturing Web sites' structure. We also present SGMapper, a client-side tool, which aims to facilitate navigation in large Web sites by generating highly interactive site maps using SGF Metadata.
