In spatial information sharing platform, an important use of the metadata is data searching. Traditional information sharing platform mostly search data just in the central node, which is inefficient. This paper presents a method which improves the efficiency of searching by mobilizing all the nodes of information sharing platform. That is, updating metadata of all the nodes through the synchronizing mechanism of metadata catalog service, to make each node has backup of other nodespsila metadata. This synchronizing mechanism is achieved by the way of message-driven mechanism and calling remote web services.
