摘要

In order to provide a basis for quantitative and qualitative assessment of SDI-performance, a clear definition and a theoretical framework for SDI are needed.From the various definitions and frameworks of SDI available in the literature, theproductional and the geographic information process perspective were selected,combined and extended. From the productional perspective, SDI-development is adynamic process in which suppliers and users of spatial data interact to add value tothe data by using them in applications and processes. The geographic informationprocess perspective incorporates the "information acquisition — delivery — usage"chain. The extension proposed in this article leads to a network perspective on SDI.The nature of this perspective is described for the Flemish SDI. Its applicability tocharacterise and underpin the assessment of SDI is tested using a Social NetworkAnalysis (SNA) focusing on the network structure parameters "density", "distance"and "centrality". The SNA confirms the applicability, usability and extensibility of the network perspective to characterize the SDI, to describe the data flows betweenstakeholders and to analyse the behaviour of the different (types) of stakeholderswithin the network. We conclude that SNA should likely be complemented by animpact analysis of different SDI setups on business processes which will provide agood basis for a holistic SDI-performance assessment.
