This paper introduces a framework for the evaluation of geographic information (GI), divided into representational and communicative aspects. The representational component is concerned with how ‘real-world’ phenomena situated in space and time come to be represented or modelled in GI, considered at ontological, modelling and system levels. The communicative component of GI is concerned with how representations of GI are understood by the users of the information, considered at relevance, commodification, exploration and management levels. This paper attempts to bring together the previous work in all these areas into an evaluative framework so that creators and users can assess the validity and success of the representational and communicative process overall. This paper also outlines the architecture of a client-server geolibrary designed for information sharing. This kind of architecture provides a distributed and open platform for the development of GI networks, upon which more productive use of GI can be built in future.
