Abstract
Spatial Data Infrastructures (SDIs) have been developing in some countries for over 10 years but still suffer from having a relatively small installed base. Most SDIs will soon converge around a service-oriented-architecture (SOA) using IT standards promulgated primarily by the Open Geospatial Consortium (OGC) and ISO Technical Committee 211. There are very few examples of these types of architected SDIs in action, and as a result little detailed information exists on suitable governance models. This paper discusses the governance issues that are posed by SOA-based SDIs, particularly those issues surrounding standards and services management, with reference to an Australian marine case study and the general literature. A generalised governance framework is then postulated using an idealised use case model which is applicable for "bottom-up," community-based initiatives. This model incorporates guiding principles and motivational and self-regulation instruments that are characteristically found in successful open source development activities. It is argued that harnessing an open development model, using a voluntary workforce, could rapidly increase the size of the SDI installed base and importantly defray infrastructure build costs.
