A Lightweight Protocol between Digital Libraries and Visualization Systems

A lightweight protocol, VIDI, is proposed to enhance the interoperability of digital libraries (DLs) and visualization systems (VIS). VIDI is related to the Open Digital Library project, which encourages a component-based approach to the construction of digital libraries, implemented by extending the Open Archives Initiative Protocol for Metadata Harvesting. VIDI adds in the concept of a registry of transformers to convert between common metadata and visualization formats. Design and implementation discussions of VIDI explain its feasibility, flexibility, and generality
