One of the most challenging problems in grid environments concerns the matchmaking between resource requests and offers. As it happens in the physical economy, grid economy must be supported by services that locate resources based not only on their characteristics, but also on market-related properties, offerspsila and requestspsila properties and constraints, as well as on declarative specifications of peerspsila (providers and consumers) features. Resource retrieval in the context of a grid economy extends the notion of resource matchmaking to the process of discovering those markets that trade resources through market orders. This paper describes an ontology that represents resource orders (offers and requests) in a market-oriented resource retrieval process, showing preliminary results of its utilization for the retrieval of traded resources.
