  As Grids are emerging as the next generation service-oriented computing
platforms, they need to support Grid economy that helps in the management of
supply and demand for resources and offers an economic incentive for Grid
resource providers. To enable this Grid economy, a market-like Grid environment
including an infrastructure that supports the publication of services and their
discovery is needed. As part of the Gridbus project, we proposed and have
developed a Grid Market Directory (GMD) that serves as a registry for
high-level service publication and discovery in Virtual Organisations.
